Hi Nicolas,

What is the version of Kamailio you are using ? Could you show us a piece of code to understand what are you doing ?

Kind regards. -- Ludovic Gasc Lemaire (GMLudo)

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 ??

• 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 ?

Hello Nicolas,

Why dont you use carrier route module to strip and add smth. you can choose your own routing logic depends on response code.

Best regards.

Hi Ludovic,

Version of Kamailio is 5.1.7

Maybe with these few lines it can help ?

route[Out] {

## If first time in this route, go to first destination.

$ru=$ru;

route(RELAY);

}

failure_route[MANAGE_FAILURE] {

if (t_branch_timeout () ){

# Failure with that ID -> ID+1;

route(Out);

}

}

branch_route[MANAGE_BRANCH] {

###Get the IP-Address based on the ID of the next-hop and send the SIP message

$ru = "sip:" + $rU + "@" + $var(IpAddress) + ":5060";

}
