Hi,
I've attatched the dump you requested.
However from a little different setup (I am not at my testlab right now)
Xlite eyebeam calling an GXP-2000.
What I see from my openser log is:
ERROR: forward_reply: no 2nd via found in reply
I hope this is not a script error...
I will try tomorrow to replicate the exact test that I did earlier.
Mvh,br

Hello,
could you make a complete network trace and send it? As I can see in the
200OK sent by OpenSER to the CANCEL, there is a Via header pointing to
caller's address. Since the CANCEL was generated by OpenSER (at timeout)
there should be only one Via header with OpenSER's address.
You can use ngrep on the same system as openser:
ngrep -qt port 5060
Cheers,
Daniel

Hi,
I've got both xlite (linux-version), Grandstream Bt-102, GXP-2000 and
cisco 7960 (7.5)
The problem is for all phones, except when I call the Cisco 7960......
