3CX Q & A

Please view our list of frequently asked questions and associated answers regarding 3CX, ACC, and VoIP services.  Please contact ACC Telecom with any additional questions or concerns.
 

3CX Hosting & SIP:

Does 3CX host a private cloud?

3CX is a software package, and while 3CX does provide a hosting service, this is not a requirement, and 3CX can be installed on ACC’s AWS Cloud environment, your own hosting account, or on an on-premise device.

Can 3CX be hosted behind a NAT?

Yes, 3CX can be hosted behind a NAT.

How does 3CX Cloud PBX differ from other Cloud-based/Hosted PBX providers?

There are 3 major differences between 3CX and Hosted PBX systems.

  • Flexibility & Control:  3CX is a software-based PBX, so YOU get to decide where to run that software-- either on a server at your business' premise, in a virtual server environment, or in the cloud with ACC Telecom.  ACC uses Amazon AWS for our Cloud servers.
  • Price:  3CX does not charge per-user extension fees, application fees, or licensing fees.  Pay annually or purchase for a one-time cost.  3CX Pricing starts at $0 for the Standard 4 SIM Call License.
  • Applications:  With 3CX, every user has access to every application available for no additional cost.
What are the AWS cloud server size recommendations for a 100-user 3CX company?

Our recommendations for a 100-user company housing the 3CX on an AWS server are as follows:

  • CPU (amount/cores, and type/speed)—Intel Core i7-3770 Processor (8M Cache, up to 3.9 Ghz)
  • Ram—8-10 GB
  • Type of HDD (HDD vs. SSD)—SATA 100 GB
  • HDD space requirements—Minimum of 100 GB.  If using call recording, then you will need more space.
  • Bandwidth-- this is difficult to answer as bandwidth on AWS is determined by your company's usage.
Are your SIP Trunks certified for use with 3CX?

Yes, our SIP Trunks are 3CX certified. This means that our SIP Trunks have gone through a rigorous testing and approval process by 3CX.  As a 3CX certified sip provider, we receive priority support and each new version of software updates are tested against our SIP technology before release.

Can we reuse our existing phones?

Depending on the models, yes. Please contact us with your make/model of IP phone to verify compatibility. Some older phones are not supported.

Can we order a 3CX license and setup the system ourselves?

Yes, 3CX licenses are available to order without having to order other services from ACC Telecom-- such as Cloud Hosting, SIP/VoIP, or Programming/Installation Service.  If you feel comfortable with programming and installing your own 3CX system, then go for it.  We are here to help if you need it. 🙂

Note:  For online 3CX License purchases, please allow up to 3 hours to receive your 3CX license key via email.

3CX Features:

When hosting a 3CX Video Conference, does it require a client-side software to be downloaded?

No, 3CX WebMeeting & Video Conferencing application is using Google’s WebRTC platform so there are no downloads or plug-ins needed.  The client will simply click a URL link to access the video & web conference.

Can you disable individual features per user?

There are certain features that can be limited or disabled per extension/user.  A few examples include call recording, having the ability to schedule a 3CX Video-Web Meeting, screen sharing, and accessing their web client account offsite.  Please contact ACC Telecom with specific feature removal requests.

Does 3CX offer faxing via email?

3CX supports inbound faxing to emails.  Outgoing faxes will need the use of an FXS gateway and an analog fax machine to be sent.

Is the failover between primary & backup 3CX automatic?

Yes, the failover is automatic. It is based on DNS. Basically, the phone, PC software, and DNS will be looking to the server via a hosted name and when the primary goes down that DNS record will be updated to point to the IP of the backup server. The phone will reset and register to the backup one almost instantly.

3CX Integrations:

What type of CRM integration do you get with 3CX?

3CX integration with various CRM systems will produce very useful, efficient call handling and will become a very integral part of your daily business interactions with clients.  With the integration, when a call comes in, it will create a ticket in the CRM. Once the ticket generation process starts, the options are endless.

Examples include (but are not limited to):

  • Call can create a new contact.
  • Calls that have a matching phone number to a customer in the CRM will auto-populate the new ticket with that requester's information, and user data, such as email, phone numbers, etc.
  • If call queues are set up, you can set triggers to automatically set aspects of the ticket, such as tags, categories, subcategories, Assignee’s, etc. depending on the queue the call came in from.
  • You can trigger calls directly from the CRM utilizing the click2call feature in 3cx or integrated CRM dialer.
  • Voicemail ticket creation- when a voicemail is left, it can create a ticket with the voicemail for follow up via CRM.
  • Ticket creation when an outbound call is placed to external numbers.

These are some of the primary use cases with 3CX/CRM integration. Keeping record of all interactions with customers is key and this does exactly that.

Does 3CX allow for API Integrations?

Yes, API integrations are welcome and encouraged!  We want your 3CX business communications system to be the most efficient, effective tool for your unique organization!

Do you integrate with any DLP systems?

3CX relies on 3rd party DLPs (Firewalls, IDS, etc.) at the network level to prevent access to the PBX.  3CX also has a built in anti-hacking tool, which maintains certain thresholds, where if exceeded, will place offending IPs into a blacklist. We also maintain a global blacklist which is distributed amongst 3CX systems to help prevent malicious attacks across the world.

Do you have any integration with GMail/Gcalendar/GSuite?

Google integration will be available for SSO in Version 18 (Admin and extension login). Google Calendar is used as one of the calendaring methods used for scheduling conferences.

Do you have any integration with Google Meet?

No, 3CX offers its own video platform that is highly secure, encrypted, and HIPAA compliant (assuming you choose to store all meeting data locally so it is completely confidential).

What is the difference between Ring Groups vs Call Queues?

Ring Groups vs. Call Queues:

Ring Groups- Ring groups can be either 'ring all' or 'prioritized ring' based on order in the group. With ring groups, the call rings the proper personnel assigned to that group then routes to a terminating destination, usually a voicemail box based on programming.

Extensions in a ring group can only receive one call at a time from that ring group, so if a user is already on a call the next call from that ring group will not ring that user, it will ring only the available users.  If all users in the ring group are busy or are in Do Not Disturb (DND) the call will immediately route to the terminating destination.

Call Queues- Call queues are a call center feature.  Agents are added to the queue, and any calls to that queue are held until someone is available to take the call.  The queue has various routing routines to choose from: ring all, prioritized hunt, round robin, longest waiting, least talk, (just to name a few), as well as skilled based routing such as skilled based ring all, skilled based hunt random start, skill based round robin and skilled based fewest answered.

Various other options come into play with queues such as announce position in line, offer a call back, play an intro prompt before the call is sent to users, set a queue as priority over others, etc.  There is also an option to set a queue time out or max callers in queue.

What type of CRM integration do you get with 3CX?

3CX integration with various CRM systems will produce very useful, efficient call handling and will become a very integral part of your daily business interactions with clients.  With the integration, when a call comes in, it will create a ticket in the CRM. Once the ticket generation process starts, the options are endless.

Examples include (but are not limited to):

  • Call can create a new contact.
  • Calls that have a matching phone number to a customer in the CRM will auto-populate the new ticket with that requester's information, and user data, such as email, phone numbers, etc.
  • If call queues are set up, you can set triggers to automatically set aspects of the ticket, such as tags, categories, subcategories, Assignee’s, etc. depending on the queue the call came in from.
  • You can trigger calls directly from the CRM utilizing the click2call feature in 3cx or integrated CRM dialer.
  • Voicemail ticket creation- when a voicemail is left, it can create a ticket with the voicemail for follow up via CRM.
  • Ticket creation when an outbound call is placed to external numbers.

These are some of the primary use cases with 3CX/CRM integration. Keeping record of all interactions with customers is key and this does exactly that.

Does 3CX offer A.I. Technology Integrations?

Yes, with API integrations A.I. Technology is possible to integrate into your Contact Center; however, we would need more information on exactly how you would like to use it to determine if it can be supported.

3CX Security:

Are retention policies for data stored on your network configurable?

Yes, 3CX offers auto-cleaning options that can be adjusted via the management portal. Examples include automatic deletion of voicemails and call recordings after X amount of days, and/or the ability to export data to an offsite location for additional storage (FTP, SMB, SFTO-SSH, Google Bucket, etc).

How can we ensure that we are talking to your service?

All communications to and from the PBX are secured via SSL communications.  3CX utilizes Let's Encrypt SSL certificates, issued free of charge and renewed as long as the license is valid.

Do you support mutual authentication between server and client?

All communications are authenticated according to the SIP protocol (RFC 3261).

Do you support SRTP over DTLS?

Yes. Audio communications between 3CX and its applications (mobile) as well as the SBC, and the Web Client are secured via DTLS.

Do you support SSO authentication with Azure AD?

Yes, this is supported in V18.

Is 3CX HIPAA Compliant?

HIPAA compliance does not apply to software vendors directly but to the organizations that may store, process,  and transmit electronically PHI data.  As such, ACC Telecom's SIP Trunk Service and Amazon AWS Cloud Servers are certified as HIPAA compliant.  Although 3CX software itself is not audited for HIPAA compliance specifically, both  the 3CX Business Communication System and the 3CX Web-Video Conferencing software are secure by design.

Since HIPAA requires physical, administrative, and technical safeguards, customers would need a certified auditor to check their network infrastructure, endpoints, and company policies to remain fully compliant.

What Encryption is used in General?
There are various encryption features used in 3CX:
  • ​HTTPS is used for any web communications from outside LAN, including the Web Client, Web Chat, SMS, online management console access, provisioning of phones, client presence statuses/unified communications information, and communications with the 3CX Cloud Services.
  • TLS 1.2 and strong ciphers are enforced by default (option is under Settings --> Security).
    You can run a scan of your HTTPS port (commonly 5001 or 443) with standard tools like Qualys SSL Labs for more details.  It ranks as A+ by default.
  • 3CX mobile apps use the 3CX Tunnel to place calls.  The tunnel uses a custom authentication protocol and transmits SIP over TLS, and audio over SRTP, and applies for the 3CX Session Border Controller to connect remote headphones.
  • 3CX uses HTTPS for Web Clients and WebMeeting static content, Websocket Secure for notification channels, and WebRTC with DTLS/SRTP for the actual calling with the strongest match of transport (TLS 1.2 by default) as well as cyphers supported by the server and browser.
  • IP Phones use standard SIP/RTP without encryption other than for SIP authentication digests by default, but can be configured to send signaling in Secure SIP / SIP TLS, and media in SRTP.
  • TLS 1.2 and strong cyphers are enforced as default (option under Settings --> Security). Some of those cyphers are using 128 bit or 256 bit encryption; ranking A by Nmap.
  • Secure RTP implementation is standard as per RFC3711. This standard defines 3 possibilities: AES-CTR, AES in f8-mode, or NULL = no encryption. We are using the AES-CTR method which allows AES_CM_128_HMAC_SHA1_80 and AES_CM_128_HMAC_SHA1_32 cyphers.
  • Push notifications to the mobile app clients are encrypted through Apple APN (TLS over HTTP/2) and Google FCM (HTTPS) standard protocols.
  • Email notifications are sent through the 3CX SMTP by default using TLS 1.2 for data-in-transit.
  • Backups are password protected and encrypted using AES CBC 128 bit.
  • Live web chat and SMS are encrypted via the SSL certificate which is used to install and access the PBX. Communication to/from the PBX is therefore encrypted given that it is over HTTPS.
  • In addition to all of the above, there are no default credentials hardcoded; all are random and unique to each entity and complex.
