18.0 Update 9 (Build 20) Calling Older Version of 3CX Issue

[stavros.christodoulou]

When calling from Version 18.0 Update 9 (Build 20) older version of 3CX, immediately after the call is answered the call is terminated.

I have the same this issue with two different systems.

I am not sure if the issue is on our system or remote systems.

Thanks,
Stavros

Regarding your issue, how are calls made between these systems? Are they 3cx systems bridged together or using supported sip trunks making and taking calls?

 

[stavros.christodoulou]

There is no bridge between the systems, just a normal SIP call.

The SIP trunk is not supported, but it worked just fine before the last update.

Unfortunately, we don't have many options to choose from in Cyprus.

Hi Stavros,

Can you enable verbose logging under Dashboard --> Activity log --> Settings and make a few tests? Also run a pcap while making the calls and gather all data so our support can review them.

Please let me know where to send the captured data.

Thanks,
