Hi Sebastian,

thanks for reporting back the results. On a second thought I updated the 
patch a bit to use a local variable for backup in order to allow nested 
execution of event_route[tm:local-request] which can be triggered by 
sending local generated requests. The commit was:

http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=08798a6d06b628fa5888ded867c5d18416b9f013

I will backport to 3.1 soon.

Cheers.
Daniel
