[OpenSIPS-Users] Problem with Opensips routing Reinvite ACK

[Kennard_White at logitech.com]

HI Nauman,

Just a guess, but does the ACK have a different R-URI than the reINVITE (as
sent by the client)? I ask because the 200 OK to the reINVITE carries a
contact address which is used to update the peer address of the dialog
state, which shows up as the R-URI of the ACK.

Regards,
Kennard

Hi Nauman,

Do you get any errors in log regarding TLS connection or others?

Also, after loose_route() print via xlog the $ru and $du to see where
opensips tries to route the ACK.

Bogdan

Reinvite due to (Hold) from UA the Sip provider gets the invite and sends
200K to which the UA responds with an ACK , however Opensips does not seem

initally started this has the same route set, yet that reaches the
provider.
