Hi Bill, what I can tell you is that the content length describes the length of the body of the NOTIFY message. And because this NOTIFY doesn't have a body the content length is 0. When I look at the RFC 3842 the information Message-Waiting, Message-Account,.. has to be as text in the body of the NOTIFY message and not as headers in the message (http://tools.ietf.org/html/rfc3842#section-3.5). There are also sample messages (http://tools.ietf.org/html/rfc3842#section-4). Regards, Matthias Jamieson, William W schrieb: > I have it working somewhat now but I notice on the wire that the content-length is zero. It's supposed to be the size of all the custom headers from what I can tell from the RFC. Is there a standard way of setting this? Also, I'm not getting the notification from ClientSession::OnIncomingSIPMessage when the server sends back it's status 100 "Trying" packet (see capture below). > > Here's what went on the wire. It shows an Internal Server Error but I'm not sure it is from the content length being zero. In the last version of the MWI service, I wrote my own SIP commands to do this, I found that I had to use Invite to get it to work even though Dialogic Support was telling me that they accept Notify and they reminded me that Invite may go away since it is not the standard. I just assumed that it was because I had written my own SIP commands to do it. I'll keep at this and maybe try it against our Cisco CM to see how it behaves. > > > > No. Time Source Destination Protocol Info > 488 09:02:49.359600 130.97.35.171 130.97.10.5 SIP Request: NOTIFY sip:3768720@130.97.10.5:5060 > > Frame 488 (586 bytes on wire, 586 bytes captured) > Ethernet II, Src: Dell_4e:64:f8 (00:21:9b:4e:64:f8), Dst: Cisco_f3:26:45 (00:18:ba:f3:26:45) > Internet Protocol, Src: 130.97.35.171 (130.97.35.171), Dst: 130.97.10.5 (130.97.10.5) > User Datagram Protocol, Src Port: vtsas (5070), Dst Port: sip (5060) > Source port: vtsas (5070) > Destination port: sip (5060) > Length: 552 > Checksum: 0xeb12 [correct] > Session Initiation Protocol > Request-Line: NOTIFY sip:3768720@130.97.10.5:5060 SIP/2.0 > Message Header > From: <sip:tes...@op...>;tag=5385369e3efe18109d428376cc92421d > To: sip:3768720@130.97.10.5:5060 > Via: SIP/2.0/UDP 130.97.35.171:5070;iid=417;branch=z9hG4bK5385369e3efe18109d438376cc92421d;uas-addr=130.97.10.5 > CSeq: 1 NOTIFY > Call-ID: 5385369e-3efe-1810-9603-8376cc92421d > Contact: <sip:130.97.35.171:5070> > Event: message-summary > User-Agent: Sample UA > Max-Forwards: 70 > Messages-Waiting: yes > Message-Account: sip:test_account@localhost > Voice-Message: 1/1 > Content-Length: 0 > > No. Time Source Destination Protocol Info > 489 09:02:49.374563 130.97.10.5 130.97.35.171 SIP Status: 100 Trying > > Frame 489 (399 bytes on wire, 399 bytes captured) > Ethernet II, Src: Cisco_f3:26:45 (00:18:ba:f3:26:45), Dst: Dell_4e:64:f8 (00:21:9b:4e:64:f8) > Internet Protocol, Src: 130.97.10.5 (130.97.10.5), Dst: 130.97.35.171 (130.97.35.171) > User Datagram Protocol, Src Port: ibm-pps (1376), Dst Port: vtsas (5070) > Source port: ibm-pps (1376) > Destination port: vtsas (5070) > Length: 365 > Checksum: 0x2aa2 [correct] > Session Initiation Protocol > Status-Line: SIP/2.0 100 Trying > Message Header > From:<sip:tes...@op...>;tag=5385369e3efe18109d428376cc92421d > To:sip:3768720@130.97.10.5:5060 > Call-ID:5385369e-3efe-1810-9603-8376cc92421d > CSeq:1 NOTIFY > Server:PBX-IP Media Gateway/2.1 > Via:SIP/2.0/UDP 130.97.35.171:5070;iid=417;branch=z9hG4bK5385369e3efe18109d438376cc92421d;uas-addr=130.97.10.5 > Content-Length:0 > > No. Time Source Destination Protocol Info > 490 09:02:49.375037 130.97.10.5 130.97.35.171 SIP Status: 500 Internal Server Error > > Frame 490 (443 bytes on wire, 443 bytes captured) > Ethernet II, Src: Cisco_f3:26:45 (00:18:ba:f3:26:45), Dst: Dell_4e:64:f8 (00:21:9b:4e:64:f8) > Internet Protocol, Src: 130.97.10.5 (130.97.10.5), Dst: 130.97.35.171 (130.97.35.171) > User Datagram Protocol, Src Port: ibm-pps (1376), Dst Port: vtsas (5070) > Source port: ibm-pps (1376) > Destination port: vtsas (5070) > Length: 409 > Checksum: 0x8abc [correct] > Session Initiation Protocol > Status-Line: SIP/2.0 500 Internal Server Error > Message Header > From:<sip:tes...@op...>;tag=5385369e3efe18109d428376cc92421d > To:sip:3768720@130.97.10.5:5060;tag=27313246313536410067E556 > Call-ID:5385369e-3efe-1810-9603-8376cc92421d > CSeq:1 NOTIFY > Server:PBX-IP Media Gateway/2.1 > Via:SIP/2.0/UDP 130.97.35.171:5070;iid=417;branch=z9hG4bK5385369e3efe18109d438376cc92421d;uas-addr=130.97.10.5 > Content-Length:0 > > -----Original Message----- > From: Joegen Baclor [mailto:joe...@gm...] > Sent: Thursday, April 16, 2009 11:11 PM > To: ope...@li... > Subject: Re: [OpenSIPStack] MWI Notify > > Hi Bill, > > Download the latest OpenSIPStack from CVS.
