Hi Andreas:
can you try
the attached patch? Just add the line as shown in the
patch. It should allow "PRACK" messages and make the stack reply to
them correctly.
Thank you for this - the signalling should now work correctly, as the
call connects immediately once the internal extension 221 (against which
osmo-cc-sip-endpoint registers) is called. There is one issue remaining
- once connected, no audio is transmitted. I don't believe this is
related to this patch, though, as my Sipgate account continues working
normally with the patch applied. As I am testing this in an openSUSE VM,
I suspect it will be more of a firewall issue - or perhaps yet another
Auerswald issue. I will be looking into this in more detail a little
later today. I'm also attaching a SNGREP capture just in case this were
helpful. Thank you and
I've also created an Auerswald trace. The relevant IP addresses are
10.1.2.1 for the PBX and 10.1.1.14 for the VM. I'm noticing a few ICMP
failures (destination host unreachable) which could be indicative of a
firewall problem in the VM, but I'm not really sure this actually causes
no audio to be transmitted. I'm glad for any indication as to what this
could be caused by, and I'll continue investigating the firewall issue also.
Best regards,
Markus
