<pre>Hello,
I have two opensip servers, exactly same configuration, but one is acting
different. This is the call flow.
Origination -- Invite------------> Opensips
Origination < 100 Trying ------ Opensips
---------------------------------------Opensips ----invite --> End user
(freeswitch)
----------------------------------------Opensips <--- 100 trying --
Freeswitch
----------------------------------------Opensips <-- 183 Ringing --
Freeswitch
Keeps waiting and never forward 183 back to Origination.
While 2nd opensips works just fine/
MTU is 1500 on both.
Working Server versions
Centos 5.2, Openisps 11-2
Not working, version (Different OS, same version of Opensips)
Cent OS 5.4, Opensips 11-2
Below is the full trace. Any hint to fix this will big help. I am
suspecting fragmented packet size in 183 Session Progress, but not sure how
to fix it. If the packet is not fragmented all works fine.
Did some more testing, if I route the call to another IP, that works fine. So something very specific to this IP only.
This is original trace, ALL IPs has been modified for security.
