[OpenSIPS-Users] Arbitrary contact added in 302 generated responses

[Bogdan-Andrei Iancu]

Hi Francisco,

First of all, maybe it will be a good idea to upgrade to OpenSIPS 1.5.1 
- along the versions many bugs were fixed and 1.2 is a really old one.

Have you tried to place an xlog and print the fwdbusy avp just before 
the avp_pushto() ?

Regards,
Bogdan
