Hi Craig, Yes, when I was implementing Call Pickup I had few problem with Cisco phone.
May be you can try to implement Call Pickup using Register and Refer message. Thanks Sandeep Sahai -----Original Message----- From: Craig Carr [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 17, 2002 5:44 PM To: Craig Carr Cc: [EMAIL PROTECTED] Subject: [Sip-implementors] Call pickup with replaces Hi. I am trying to implement call-pickup via replacing an early dialog at the originator with Cisco 7960 phones. The problem is that post receiving the INVITE with the replaces header the phone sends 100 then 180 responses instead of the 200 response in the rfc replaces draft. Here is the original ringing message SIP/2.0 180 Ringing Via:SIP/2.0/UDP 10.4.0.6:5060 From:"KEVS 1"<sip:[EMAIL PROTECTED]>;tag=003094c35afe028343b7d94a-690f4901 To:<sip:[EMAIL PROTECTED];user=phone>;tag=594EC95-C79 Call-ID:[EMAIL PROTECTED] CSeq:101 INVITE Content-Length:0 Date: 02 Mar 1993 02:00:45 GMT Server:Cisco-SIPGateway/IOS-12.x Here is the INVITE with replaces INVITE sip:[EMAIL PROTECTED] SIP/2.0 via:Sip/2.0/UDP 10.4.54.1:5060 Via:SIP/2.0/UDP 10.4.54.32:5060 From:"Hugh Grant"<sip:[EMAIL PROTECTED]>;tag=003094c35e27001d4bd97a0f-1d8d81d8 To:<sip:*[EMAIL PROTECTED]> Contact:sip:[EMAIL PROTECTED]:5060 Call-ID:[EMAIL PROTECTED] CSeq:101 INVITE Record-Route:<sip:[EMAIL PROTECTED]:5060;maddr=10.4.54.1> Content-Type:application/sdp Content-Length:242 Date: 17 Dec 2002 22:05:23 GMT Expires:180 Replaces:[EMAIL PROTECTED];to-tag=594EC95-C79;fro m-tag=003094c35afe028343b7d94a-690f4901 User-Agent:CSCO/4 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, NOTIFY Supported: replaces etc.... Do the Cisco phones not implement this feature properly?, am I doing something wrong?. Many thanks.
