Rollback to v15.5 SP3

[Moatasem Taha]

I've updated to v15.5 SP4 and that killed my outgoing calls.
We are using an Enterprise SIP Trunk which require a custom entry in the Outbound, P-Preferred Identity : Host Part
In SP3 that worked fine and we could make calls, after the upgrade to SP4 the outgoing calls stopped.

We did a Wireshark packet capture and found the header in the SIP invite doesn’t include this part ;otg=xxxxxxxx

Anything from the “;” is dropped.

Now we can receive calls but can’t make any.

I need to rollback to SP3 ASAP.. but I can't find the Linux version anywhere to download.

the way on how to install a specific version of 3CX in linux is

apt-cache policy 3cxpbx
Determine the version you are looking for (SP3 would be: 15.5.8801) and if it is still available
apt-get install 3cxpbx=15.5.8801

that might buy you the time to address the case with the provider as ; uri params should be created outside a dialog. To be always save, use a supported provider we test.

just to be clear, this in not intended to run inline to an existing installation on the host!
