[OpenSIPS-Users] UDP to TCP issue with Re-INVITE

[Mickael Hubert]

Hi all,
I make a lot of others tests.
I have a new opensips with very simple conf.

Asterisk (tcp:192.168.10.204:8060) --> OpenSIPS (tcp:192.168.10.203:8060)
--> Public SBC

With the scenario, All calls work like a charm (Re-invite from public SBC
is forwarded to asterisk correctly).
OpenSIPS add Record-route headers and Via

INVITE from OpenSIPS to Public SBC:

INVITE sip:192.168.10.203:8060 SIP/2.0
Record-Route: <sip:192.168.10.203;transport=tcp;r2=on;lr;did=e0c.7aea7b33>
Record-Route: <sip:192.168.10.203:8060
;transport=tcp;r2=on;lr;did=e0c.7aea7b33>

When I activate topology hiding on this OpenSIPS, It don't add record-route
header and via

Asterisk (tcp:192.168.10.204:8060) --> OpenSIPS (tcp:192.168.10.203:8060
with Topology Hinding) --> Public SBC

INVITE from OpenSIPS to Public SBC:

INVITE sip:192.168.10.203:8060 SIP/2.0
Via: SIP/2.0/TCP 192.168.10.203:5060

And with topology hiding activate, the Re-Invite from UAS (public SBC)
isn't forwarded to asterisk !
Idem, with topology hiding, a BYE from UAS (public SBC) isn't forwarded
too. But the BYE from UAC is forwarded correctly

Is there a bug or misconfiguration for topology hiding module ?

thanks in advance
