[Asterisk-Users] forward_msg: no 2nd via found in reply

[Cyprien Simons]

Hi everybody,

I'm trying to use Asterisk as SUA with SER. But Asterisk doesn't 
succeed to register the Asterisk user to SER... the standard error output of 
SER tell me:
"ERROR: forward_msg: no 2nd via found in reply"

the SIP message looks like:

I'm using ser 0.8.12, SuSE 9.1, Asterisk 0.9.1

I am quite new on Asterisk and SER, and I am trying to pursue the work of 
another person, 
so if something in it seems stupid, don't hesitate to tell me so...

And sorry if it seems more a SER problem, but I already post it on the SER 
mailinglist and it didn't help...
