Hello,
my guess is, you have a problem with udp/ip fragmentation. You reinvite is much larger
then the initial invite (~1200 vs 1600 Bytes). Talk to your provider so he can fix his
firewall or other settings. Alternative ask for a switch to TCP.
As a last resort, you can try to reduce the size of the reinvite somehow. Like removing
not neccessary SIP header or codecs from the SDP.

Hello,
I am trying to understand a problem we have with reinvites. When there is a
reinvite on the call our provider refuses to receive the reinvite and the
call is dropped.
The setup is the bellow:
UA-> Kamailio1 -> Kamailio2 -> Provider
On Kamailio2 we have Topos enabled.
Looking on the trace I can see that on the second invite, Kamailio does
send out the original contact and not the one that was originally send out
to the provider. Is this correct? Is this breaking the call?
Bellow the trace and the flow from Kamailio2 until the second reinvite. All
reinvites are the same as per the last
Thank you for your help!
