Our 3CX server sometimes starts reporting errors when trying to connect an outgoing or incoming call. We are using VoiceFlex and this problem occurs intermittently. Sometimes it fixes itself, sometimes I have to restart 3CX.

Is the problem with 3CX or VoiceFlex? VoiceFlex haven't been able to find any problems at their end.

This is an example of the log

Re: 3CX sometime fails to connect - 488 Not acceptable here

1. Please specify version of 3cx and license type
2. Log of successful call (from console) AND 3CXMediaserver.trace.log (or just wireshark capture of the call)
3. Log of unsuccessful call (from console) AND 3CXMediaserver.trace.log (or wireshark capture of the call)

Thanks
 
VoiceFlex. sometime fails to connect - 488 Not acceptable he

The version that I have is the latest available on your web site - 8.0.10824.716. We are currently using the Free licence. We will consider purchasing a licence once we are confident that this system will work reliably. I have another outstand message thread regarding the daily 3CX crashes that we are getting.

Here are the logs:

Successfull call:

VoiceFlex sometime fails to connect - 488 Not acceptable her

I think you need to ask VoIP provider for help to troubleshoot this issue.
488 response means that the SDP which was offered by PBX is not acceptable by remote party(VoIP provider)

But both offers are the same.

Thanks for information
