Hello! I'm facing a problem concerning MWI. The problem is:
The phone switches off the MWI exactly at the moment the second NOTIFY package for one voice mail arrives. The phone switches off MWI independently if the voice mail has been acknowledged or not before. The behavior in detail: - Once each hour, phone sends SUBSCRIBE - Asterisk receives incoming voice mail for Device 200. - some time later: Phone executes a REGISTER - Directly after succeeded REGISTER, asterisk sends Notify - Notify is acked by phone The content of the packages ---------------------------------------------------------------------- SUBSCRIBE Contact: <sip:1234@192.168.16.73:7594> User-Agent: C610 IP/42.231.00.000.000 Event: message-summary Expires: 3600 Allow: NOTIFY Accept: application/simple-message-summary Content-Length: 0 SIP/2.0 200 OK Expires: 3600 Contact: <sip:192.168.16.70:5060> Allow: OPTIONS, SUBSCRIBE, NOTIFY, PUBLISH, INVITE, ACK, BYE, CANCEL, UPDATE, PRACK, REGISTER, REFER, MESSAGE Supported: 100rel, timer, replaces, norefersub Server: FPBX-13.0.195.19(13.24.0) Content-Length: 0 ---------------------------------------------------------------------- After REGISTER: ---------------------------------------------------------------------- NOTIFY Contact: <sip:1234@192.168.16.70:5060> Call-ID: 7a5ee160-47a1-4efa-b190-66843d644243 CSeq: 9921 NOTIFY Subscription-State: terminated Event: message-summary Allow-Events: message-summary, presence, dialog, refer Max-Forwards: 70 User-Agent: FPBX-13.0.195.19(13.24.0) Content-Type: application/simple-message-summary Content-Length: 49 Messages-Waiting: yes Voice-Message: 1/1 (0/0 SIP/2.0 200 OK Call-ID: 7a5ee160-47a1-4efa-b190-66843d644243 CSeq: 9921 NOTIFY User-Agent: C610 IP/42.231.00.000.000 Content-Length: 0 ----------------------------------------------------------------------- => MWI on! -> That was expected! Now happens next REGISTER and after this, the next NOTIFY (the same as shown above) is sent to the phone => MWI is switched off! If there coincidentally is a NOTIFY sequence in between ending with Messages-Waiting: no Voice-Message: 0/0 (0/0) ------------------------ Messages-Waiting: yes Voice-Message: 1/1 (0/0 the MWI will be active again (this may be achieved if mwi aggregation is turned off and the order is exactly as shown above - but that's chance). I'm wondering now: what's the generally expected behavior? Should the phone handle repeatedly sent NOTIFY packages for same voice mail as if they had been sent once or should asterisk signal the same voice mail only once and not repeatedly? Configuration: pjsip.aor.conf: [1234] mailboxes=1234@default pjsip.endpoint.conf [1234] aggregate_mwi=yes or no Thanks, kind regards, Michael -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
