[Freeswitch-users] SIP 482 "Request Merged" on parallel forking

[Carlos Eduardo]

Hey Carlos,

When I had this issue, I solved creating more sofia profiles with diferent
ports. In my case, the problem was with serial forking.

> the branch parameters, but FS interprets these requests as the same and
> merges them running the forking impossible.

> - And the only reported solution, change the T4 SIP timer to less than 4
> seconds and put a sleep() on Kamailio for each branch. I personally don't
> consider this a solution as it plays with the timers.
