I’m using 3CX Session Border Controller (SBC) 15.0.56341 to connect to a 3CX v15 SP4 server running on Server 2012 R2 in the cloud. Usually it works fine. A couple days ago, though, even after re-starting the SBC, I was getting the error "Invalid signature received: 0x10317".More...

TL;DR If your 3CXPhone app and/or your desktop phone are not able to connect to a remote 3CX server, test connectivity to the server on 3CX tunnel port 5090. If there’s no connection, on the server, check if anything is listening on that port. If not, restart the 3CX SIP/RTP Tunneling Service.More...

I’m doing a test upgrade on a local Windows 2008 R2 server from 3CX 14 to 3CX 15. A few notes and gotchas for future reference. Read these before uninstalling 3CX 14! There are several bits of information, including the 3CX 14 configuration backup, that will be lost if you follow 3CX’s instructions. Perhaps these notes will help 3CX improve the documentation and the install experience.More...

A Windows Server 2012R2 Essentials machine was returning strange results when I did a DNS query from PowerShell. I traced it back to modifications that 3CX version 14 had made to the Windows hosts file.More...

I am running 3CX 14 stand-alone on a cloud-based server with a fixed IP.
At my location, I have installed the Session Border Controller (SBC), also v14, on a local server.
When I dial out from a local phone, sometimes I just get a busy signal, even if I am dialing ext. 99 for voicemail. Running a trace on the phone, I see it is receiving a 403 Forbidden error.More...

If you want to provision unsupported phones to use with 3CX, you may come across this article on the 3CX web site: Provisioning unsupported IP phones. It looks quite helpful but it’s out of date in an important area: the location of the templates.More...

MCB Systems is pleased to announced that its CRM telephony integration product, MCB GoldLink to 3CX, is now compatible with the latest 3CX version 14.
3CX 14 uses a new version of 3CXPhone for Windows as both a softphone and to provide presence information, call logs, and other feature formerly provided by 3CX MyPhone.
MCB Systems has developed a 3CXPhone add-on called the 3CX Command Line API Plugin that allows 3CXPhone to “talk” to GoldLink. The plugin is included with GoldLink version 4 and is automatically installed and configured when you install GoldLink.
For complete information about MCB GoldLink to 3CX, visit the product page, where you can download a fully-functional 30-day trial. Existing customers can upgrade to GoldLink 4 at a discounted price.More...

Today I installed 3CX version 11 with SP4 on a new, virtualized Windows Server 2008 R2 x64. The installer downloaded and installed the Visual C++ 2010 SP1 x64 redistributable. The 3CX services started fine.
I applied Build 30295 to fix the Heartbleed vulnerability, and most 3CX services would no longer start:More...

A client running 3CX version 10 mentioned that no one was seeing voicemail indicators or getting voicemail notifications via email. I recalled that these are “paid” version features. Sure enough, his license was no longer activated. After re-activating the license, voicemail notification started working again. But why did the license become unregistered?More...
