Hi to all.
I have in my office ipLDK100 pbx connected with 3CX as VOIP provider. All works fine, but approximately one time in day I need to restart 3CX services. The problem with incoming calls from LDK, opponents are not hear each other (outgoing to LDK still OK). Once services were restarted all works fine. Logs of calls after and before restart are equal. Firewall not drops packets.
Please, help me to solve this problem.

Do I understand correctly, you are using the a Bridge trunk, in 3CX as the Master to connect to another VoIP PBX?

Has this problem always been there? If not, what happened (changed) just before this issue began?

It would seem that the voice packets are not finding their way through to 3CX, so... (without seeing your entire network set-up) my first guess would be some sort of firewall, or perhaps a router problem. For testing purposes, you may want to disable any firewalls temporarily and eliminate anything (in the 3CX server PC) that may cause this blockage.

When you restart 3CX, are you re-booting the PC/Server, or just stopping and restarting the 3CX programme?

Generic VoIP provider.

The problem begun appear after I had moved the 3CX to another server (virtual machine), at the same time the VP530 was connected as external client (TLS+SRTP). And one more detail is that external client doesn't work too when the problem arises.
3CX server connected with LDK over LAN.

Firewall settings on server:
3CXPhoneSystem.exe ALLOW
UDP 9000-9049 ALLOW

Just restarting 3CX services.

Just restarting 3CX services.
In log - both calls are processed in "by pass" mode. Both, provider and phone are in the same network. Provider configuration is not "Generic VoIP provider". Template was "Generic VoIP provider" but configuration was modified.
"by pass" means that devices are talking directly. PBX does not participate in this process.
 
I understand what you talking about, but I just say facts. Seem the problem is gone after restart server (Windows).
What ever it was, 3CX participates in this process, maybe codec negotiation or something else - I don't know. If problem with symptoms that I described not first experience, then I can send you logs.
