[SIPForum-discussion] 3pcc implementation with sip provider

Mon Oct 1 17:03:01 UTC 2007

Hi,

My question might be very simple since I am new to SIP.

The problem is that I have implemented a third part call controller following flow IV in rfc3725. I tested it using P2P module, it works fine. But when I applied it to sip server, sip.voipstunt.com, which kept sending me the 4XX message (bad request or unsupported media type) on response to my INVITE(no SDP).

I don't know what could cause the failure.

I was wondering if it is because the sip server doesn't support 3pcc messages. should both sip server and gateway support 3pcc in this situation? 

Thanks very much.

Best Regards,
