HI Anca-Maria, I have a question about this call-flow from a while back. I think there is a problem with the initial subscribe sent from openser. Specifically with the TO: header.

As you can see the phone registers with From "phone1" or we can say "Bob" as in the draft example.

I'm assuming this call flow is taken from section 6.1.2 of the draft. "Bob Registration and Subscription Flow" If you look at packet F9, note the FROM and TO headers. It looks to me that the from header is right ( from Alice:) , but the the TO: header should be To: sip:[EMAIL PROTECTED] ( to BOB) Regards, Andy . > NOTIFY sip:[EMAIL PROTECTED] SIP/2.0. > Via: SIP/2.0/UDP 192.168.2.8;branch=z9hG4bK8cee88d6657A1843. > From: <sip:[EMAIL PROTECTED]>;tag=42CCFC4-B67A55C1. > To: <sip:[EMAIL PROTECTED]>;tag=616c04edf3c5befd4558c7fc378ac996-514f. > CSeq: 1 NOTIFY. > Call-ID: [EMAIL PROTECTED] > Contact: <sip:[EMAIL PROTECTED]>. > Event: dialog;sla. > User-Agent: PolycomSoundPointIP-SPIP_430-UA/2.0.3.0127. > Subscription-State: active;expires=109. > Max-Forwards: 70. > Content-Type: application/dialog-info+xml. > Content-Length: 152. > . > <?xml version="1.0"?>. > <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="0" > state="full" entity="sip:[EMAIL PROTECTED]">. > </dialog-info> > > > U 2007/05/10 19:42:46.751643 192.168.2.8:5060 -> 192.168.2.132:5060 > SUBSCRIBE sip:[EMAIL PROTECTED] SIP/2.0. > Via: SIP/2.0/UDP 192.168.2.8;branch=z9hG4bK346f7948417AB725. > From: "phone1" <sip:[EMAIL PROTECTED]>;tag=43D63209-6292CADE. > To: <sip:[EMAIL PROTECTED]>. > CSeq: 1 SUBSCRIBE. > Call-ID: [EMAIL PROTECTED] > Contact: <sip:[EMAIL PROTECTED]>. > Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, INFO, MESSAGE, SUBSCRIBE, > NOTIFY, PRACK, UPDATE, REFER. > Event: dialog;sla. > User-Agent: PolycomSoundPointIP-SPIP_430-UA/2.0.3.0127. > Accept: application/dialog-info+xml. > Max-Forwards: 70. > Expires: 110. > Content-Length: 0. > > U 2007/05/10 19:43:36.753299 192.168.2.8:5060 -> 192.168.2.132:5060 > SUBSCRIBE sip:192.168.2.132:5060 SIP/2.0. > Via: SIP/2.0/UDP 192.168.2.8;branch=z9hG4bKbb45512f3A7A56D4. > From: "phone1" <sip:[EMAIL PROTECTED]>;tag=43D63209-6292CADE. > To: <sip:[EMAIL PROTECTED]>;tag=10.14816.1178815366.2. > CSeq: 2 SUBSCRIBE. > Call-ID: [EMAIL PROTECTED] > Contact: <sip:[EMAIL PROTECTED]>. > Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, INFO, MESSAGE, SUBSCRIBE, > NOTIFY, PRACK, UPDATE, REFER. > Event: dialog;sla. > User-Agent: PolycomSoundPointIP-SPIP_430-UA/2.0.3.0127. > Accept: application/dialog-info+xml. > Max-Forwards: 70. > Expires: 110. > Content-Length: 0. > >
