I don't think you have understood my question. I understand the difference between using 3PCC and REFER. My question if I have already used 3PCC to setup a call between two parties. Is it NOW possible to drop out of the signalling after an arbitrary amount of time? I am hoping that I can use Refer with replaces for this. However, I have noticed that most UA's reject REFER if 1) It is out of dialog 2) We don't HOLD the INVITE dialog within which the REFER is sent. In this situation it is obvious that I cannot hold any of the parties.

That should be in the path of SIP signaling for billing purpose. If your application requires 3PCC to be out of the signaling path, you could use REFER to achieve this provided both endpoints support it. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Darshan Bildikar Sent: Monday, April 23, 2007 1:19 AM To: [email protected] Subject: Re: [Sip-implementors] Question related to 3PCC Apologies for the retransmit. Would appreciate any pointers. I am stuck with this.

After completion of the call, I now want to drop out of the signalling path (either immediately or after an arbitrary amount of time). Is this legal? Can I send a refer with a replaces to A or B to achieve this? Another related question I've noticed that most endpoints accept a REFER (inside INVITE dialog) only if we hold the INVITE dialog first. Is this because it is inside dialog? Can I expect different behaviour if I send the request outside of a dialog?
