[OpenSIPS-Users] destroy dialog on transaction timeout and load balancer

[Bobby Smith]

Howdy Bogdan,

We've currently been using option 2 to reasonable success (a shell script /
cron), so we'll probably stick with that in the future.  I think playing
around with the new rtpproxy session timeout settings might also help keep
the problem in check.

Thanks, and thanks for the recent release!
