Hello,

 

$ru=$ru; instead of add & strip solved the issue.

 

I suppose we have to “write” the Request URI to load or execute the routing branch.

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 ??

• Call OK

 

 

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

Any suggestions ?
