[SIPForum-discussion] Call Transfer through a SIP Trunk

[Manoj Priyankara [TG]]

Dear all,

Please consider the following scenario.

Assume that there is a standard Soft Switch; and an IP PBX is connected
to the SS using a SIP trunk. 

IP PBX has a user (Say A)

An incoming call comes from an external party through the SS to user A.
User A transfers that call to an external party. (Say B). This call leg
also goes through the SS


Incoming call to A

		SIP Trunk
C-----> |SS|-------->|IP-PBX|------> A


Transfer to B

A---->|IP PBX|------->|SS|-------> B  

In this scenario, can the media be bridged from the SS and release all
the resources in the IP PBX once the call is transferred?

Thanks
BR,
Manoj
