Hi, I have the following interesting situation with SipX 3.10.2. There is a JAIN-SIP application subscribed to MWI notifications. Before the scenario presented below, there was a successful subscription and it is expiring, therefore the application sends a new subscribe. The subscription progresses nicely, the first SUBSCRIBE is challenged and now the application sends the SUBSCRIBE with the credentials.
17:55:29,661: SUBSCRIBE sip:[email protected] SIP/2.0 Call-ID: [email protected] CSeq: 2 SUBSCRIBE From: <sip:[email protected]>;tag=tag3218735 To: <sip:[email protected]> Max-Forwards: 70 Contact: <sip:[email protected]:5560> Expires: 1800 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, NOTIFY, MESSAGE, SUBSCRIBE, INFO, UPDATE Event: message-summary Authorization: Digest username="8186",realm="onrelay.local",nonce="b77e1431144dee71a8a0bc87bf4 97da94999a891",uri="sip:[email protected]",algorithm=MD5,respon se="0d188e8e591cfd58a36e71196a3210d3" Via: SIP/2.0/UDP 10.1.3.11:5560;branch=z9hG4bKd8de6d7cf6cb5e86dcb366a003d69f38 Content-Length: 0 After this message, however, 202 Accepted does not arrive but SipX immediately returns a NOTIFY. 17:55:29,694: NOTIFY sip:[email protected]:5560 SIP/2.0 Content-Type: application/simple-message-summary Event: message-summary Subscription-State: active;expires=867 From: <sip:[email protected]>;tag=b447fa6a To: <sip:[email protected]>;tag=tag3218735 Call-ID: [email protected] CSeq: 2 NOTIFY Contact: <sip:[email protected]> User-Agent: sipXecs/3.10.2 sipXecs/publisher (Linux) Date: Mon, 16 Feb 2009 17:55:29 GMT Max-Forwards: 19 Accept-Language: en Supported: sip-cc-01,timer Via: SIP/2.0/UDP 10.1.3.11:5060;branch=z9hG4bK-sipXecs-00f6464514d97a97596ee08359c3a2a423 02,SIP/2.0/UDP 10.1.3.11:5110;branch=z9hG4bK-sipXecs-b31f347bf4a3f0867d610a0925cb3884fc 75 Content-Length: 51 This confuses the JAIN-SIP stack, as there is no SUBSCRIBE dialog established, the NOTIFY goes into the void and cannot be responded to. Eventually the 202 arrives. 17:55:29,701: SIP/2.0 202 Accepted From: <sip:[email protected]>;tag=tag3218735 To: <sip:[email protected]>;tag=b447fa6a Call-ID: [email protected] CSeq: 2 SUBSCRIBE Via: SIP/2.0/UDP 10.1.3.11:5560;branch=z9hG4bKd8de6d7cf6cb5e86dcb366a003d69f38 Expires: 867 Contact: <sip:[email protected]> User-Agent: sipXecs/3.10.2 sipXecs/publisher (Linux) Date: Mon, 16 Feb 2009 17:55:29 GMT Allow: INVITE,ACK,CANCEL,BYE,REFER,OPTIONS,NOTIFY,SUBSCRIBE Accept-Language: en Supported: sip-cc-01,timer Content-Length: 0 Shouldn't 202 Accepted arrive first? The application and the server are located on the same machine, I can't imagine that this is caused by network delay.
