[SR-Users] Branches Routes

[Nicolas Breuer]

Hello,

We have a main route where we try multiple destinations (SIP Providers) one by one in case of failure.
We modify the $ru in branch routes.

I have to manipulate the $rU in the main route (adding 000 and strip 000) to create the second branch.

Otherwise I have an error in Kamailio , is it expected ??

  *   Adding 000 in main route
Feb 16 10:29:13 proxy2 /usr/sbin/kamailio[3837]: NOTICE: RU => 3280033800 (Branch 0)

  *   Strip "000" in main route
  *   Timeout of first provider (going to main route again with an other branch)

Feb 16 10:29:15 proxy2 /usr/sbin/kamailio[3840]: NOTICE: RU => 3280033800 (Branch 1)


  *   Call OK


I will now remove the prefix & strip command in main route

Any suggestions ?
