[OpenSIPS-Users] local_route not being called

Thu Jul 25 20:29:31 CEST 2013

There are many circumstances, for example,

1. You are using loadbalancer / dispatcher module, which send SIP keep
alive requests (e.g. OPTIONS or INFO message) to destination to determine
that are still available.
2. You are using media proxy / rtpproxy with media timeouts enabled, so if
media proxy / rtpproxy does not receives rtp and timeout occurs, it
triggers a BYE requests to end the call. Which you many want to track in
local_route to do accounting etc.
3. You are using dialog module with "B" flag enabled in create_dialog
method, which will result in BYE request to end points when dialog timeouts
(same way as above).
4. You are using B2BUA or topo-hiding  setup, which will result in all SIP
request duplicated but with somewhat different headers / parameters to send
to destination. All those messages will appear in local route where you can
do their accounting etc.

OpenSIPS does not generates any reply on its own, unless in special
circumstances, e.g.

1. It sends 100 Trying when you do t_relay, However, you can force opensips
NOT to send this reply automatically by specifying it a parameter to this
method.
2. It sends 408 upon T2 timer timeout for destination. You can track it in
reply_route to do whatever you want in that situation.

You can generate your own replies overriding the reply that is actually
received from destination in reply_route, or even from route block if you
do not want to (or you can not send to) an incoming request to a
destination at all.

Have a look at tutorials for more information,

Thank you.
