This article helps you recover from Backup and Restore Errors including some tips to make this operation quick and seamless. When a new major version is released, it is recommended to install the latest version.  Here is a procedure to do this. The option “Voice prompts and music on hold” should be enabled in the 3CX backup interface.  This will ensure that all your custom and system prompts together with voicemail intro-prompts are fully backed up and eventually restored.  As a 3CX Administrator, it would be good practice to delete any prompts that you are not using in your 3CX configuration, maybe customized prompt-sets which were downloaded but never used, some old IVR’s in the system etc

Introduction to the 3CX Media Server The 3CX Phone System’s main job is to connect 2 (or more) entities together for transmission of audio between them. However, there are 3 different mechanisms which can be utilized for the delivery of audio streams between 2 endpoints: Bypass Mode (Direct) Proxy Mode (Pass-Through) Transcoding Mode (Bound to Media Server) Audio streams are delivered by the 3CX Media Server. The inbuilt 3CX Media Server can recognize whether the call is an internal call an external call by making a calculation based on the comparison of the 3CX Phone System Local IP address and Subnet mask, it’s interfaces and those of the settings set on the phone or party. This is one of the 3CX Main core services. By Pass – Direct Mode In this mode, media server does not take any part in the RTP stream delivery between two sip entities. Both entities will negotiate with the PBX to send the RTP stream directly to each other.

You can do simple debugging (for ISDN, for example) on a Patton gateway by using a series of simple commands. After connecting to the gateway via telnet, type the following: login: {your username here} password: {password here} enable configure debug ccisdn signaling debug isdn event {slot} {port} all Replace {slot} and {port} with the slot and port you want to debug, for example: debug isdn event 0 0 all For the first slot and port. (To turn off debugging, type no debug all at the prompt.) The first debug command prints all ISDN layer 3 signalling messages, and call control related activity of the ISDN interface. This is a good monitor to start with when debugging ISDN. The second command logs in detail the operation on the ISDN port (protocol stack layers 2 to 3). Now attempt an ISDN call

If you are using a VOIP provider, you will need to have a firewall that supports and is configured to use static port mapping. Static port mapping is required for RTP, the protocol that carries audio, to be able to function correctly. RTP and Symmetric NAT VOIP applications use the RTP protocol to send and receive audio and video streams, tend to have problems behind a firewall or a router since RTP uses random ports to send and receive audio or video streams. Incorrect firewall configuration will cause calls made via a VOIP providers or to remote extensions to have no audio or one way audio only. When using Symmetric NAT, the firewall/router will change the port on which the audio is received, on the fly.
