[OpenSIPS-Users] Hung dialogs

[duane.larson at gmail.com]

Have you looked at the following
http://www.opensips.org/html/docs/modules/devel/dialog.html#id293895

OpenSIPS will send OPTIONS pings to whoever you want to and if they don't  
answer back because they don't recognize the Dialog then opensips will send  
a BYE to both caller and callee and kill the dialog.

Does that help any?
