Andreas, Thanks for your reply. I understand that part. Is that a best-practice to not relay a packet to yourself? I was trying to implement serial forking based on the example for voice-systems and I'm running into some issues when doing a simple t_relay() and that is when I started looking for a better way to do this.
I'm still not clear about the use of t_on_branch. In this case, when is it really called? -- Zahid -----Original Message----- From: Andreas Granig [mailto:[EMAIL PROTECTED] Sent: Thursday, July 26, 2007 1:37 PM To: Zahid Mehmood Cc: users@openser.org Subject: Re: [OpenSER-Users] t_on_branch -- using drop() question? Hi, The config is designed to never relay a request to itself, but instead do recursive route processing. So if you do a CFC to a local user, the config will take care to do a lookup before a relay, which will change the request uri to the IP of the CF target.
