[OpenSIPS-Users] Drouting use next gateway adding too many vias

[Richard Robson]

Hi,


I'm testing out new carrier which has 3 different endpoits for us to 
connect to. I've setup the 3 addresses in the DR_Rules table and the 
first call or calls to a different address directly work. however, when 
a call fails ad I select the next gateway the originating asteris box 
failed to respond to the 200 OK.

I've traced this to Asterisk compalining about too many vias in the sip 
response


this is one of the packets and you can seee the two vias.

Is there anyway to stop this, is this expected behavoir or am I doing 
something wrong?

its Opensips 2.2.2


Regards,


Richard
