[SR-Users] Double attempt to record-route, RR param not added

Sat Jan 3 21:13:32 CET 2015

Thanks Daniel.

I am now using record_route_advertised_address() to set the alternate
address rather than record_route_preset() followed by record_route().  Also,
I am able to add the tag using add_rr_param().  The documentation for the
record_route_preset function isn't clear that it actually adds the header,
so I understood that I needed to call the record_route function as well.

record_route(), record_route(string)

The function adds a new Record-Route header field.

record_route_advertised_address(address)

The function adds a new Record-Route header field using the address given.

record_route_preset(string [,string2])

This function will put the string into Record-Route

Thanks again for your help,

Ron

Hello,

you call record_route_preset() in the switch and record_route() before
t_relay(), therefore you attempt to add two times the record-route header.

I am not sure the add_rr_param() works on the header added by
record_route_preset(), to that function you can include the URI parameter
directly in the function parameter.

Cheers,
Daniel

One additional bit of information.  Here is a message flow diagram of the
call scenario.  The circled message is where the Record-Route header is
added.

I have been away from Kamailio for a while and starting working on a project
where it would be a good fit.

I am having a problem when I try to add a Record-Route header with a tag.  I
see a message in the log indicating that a Double attempt to record-route
was made, and the tag that I specified (;rtpproxy=yes), does not get
included.

I have checked-over the scripts defined in the kamailio.cfg, and I am very
sure that record_route() does not get called more than once.  Also, the log
only shows record_route being execute a single time.

Can anyone suggest how I can troubleshoot this problem further?
