Just as an after thought... do I have to apply any specific settings within the PBX administrator with regard to the call forwarding params (eg. "type of call forwarding" / "pattern setting" etc) before the appropriate diversion header info might be provided?

I have removed $istalking -- no success I'm afraid -- still no diversion info.

I am looking for the diversion info to be provided in the INVITE packet sent from the brekeke sip server to the external client application.

Thanks for the prompt response james. I am very new to brekeke, hence am familiarising myself with areas such as dialplans. I created a new dial plan, and have entered exactly as you have typed, replacing the Deploy pattern "To:xxx" with the uri of my external application server... however, still no ...

Brekeke SIP Server 2.1.6.6
Java version: Ver 6 Upd 5
OS version: Win XP SP2

Is there any way to configure Brekeke to provide DIVERSION information in the packet header (when an endpoint is diverted/forwarded on busy/no answer)?
