[SR-Users] Issue with Double Record Route

[Daniel-Constantin Mierla]

Hello,

my remark was related to the fact that you may have another
record_route*() function executed in the configuration file for the same
SIP request.

It may be simpler also from routing/security point of view to use
different ports for internal and external communications. E.g., port
5060 for communication with internal and port 5080 for external. The you
can do advertising on the listen with external port:

listen=udp:localip:5060
listen=udp:localip:5080 advertise externip:5080

Then you just need to force the socket to be used before sending out to
use the right port and record_route() will do the rest.

Cheers,
Daniel
