[OpenSIPS-Users] ACK problem when using opensips for a TLS call

[Eran Cohanim]

Hi,

 

I have the following topology in my lab:

 

              [tls]

 [UA1] ------+

                       |+  [sip peer]-------------------------[opensips]

[UA2] ------+                                           [tls]

              [tls]

 

Scenario:  UA1 calls UA2 (via opensips proxy. Meaning invite from SIP
peer is sent to the opensips and proxied back to the same SIP peer)

 

Failure:

ACK Request after "200OK" from UA1 is sent to SIP peer and then to the
opensips proxy but swallowed by the opensips proxy!

The following error appear in log:

 

Note: Using opensips 1.6.2 with TLS support (attached opensips config
file)
