[OpenSIPS-Users] several SIP phones with same SIP account

[Vlad Paiu]

Hi,

The lookup() function adds all the needed branches, it's up to you as 
the script writer on how you use those branches, by doing serial or 
parallel forking.
To do serial forking, after doing lookup(), call the serialize_branches 
core function, to order the branches based on the q value.
After that, before relaying the INVITE, arm a failure_route in case the 
first destination fails.
Inside the failure_route, call next_branches() to have OpenSIPS try the 
next branch and arm again the failure_route to repeat the same process 
in case the subsequent branches fail as well.
