BLF Subscriptions sometimes don't send an initial Notify
Hello, I have setup presence and in most cases it is working as expected. i.e. Subscription is sent to FS, FS returns Accepted then immediately FS sends the notify to the phone, thereafter all the Notify events for ringing, pickup and hangup. Great. However in some cases a subscribe to an extension does subscribe,FS sends the accepted response but a Notify is not sent out at that point. However if I call the extension the Notify works perfectly. Any ideas of what could cause the initial Notify not to be sent after the Acceptance 202? Any help would be appreciated. Regards, Steve. p.s I sent this to the list a few days ago but it didn't seem to come through on the list. Some detail info below: FS is configured as Multi-Tennant <param name="presence-proto-lookup" value="false"/> <param name="send-presence-on-register" value="true"/> <param name="manage-presence" value="true"/> <param name="presence-probe-on-register" value="true"/> <param name="manage-shared-appearance" value="true"/> <param name="dbname" value="freeswitch"/> <param name="presence-hosts" value="_DISABLE_"/> # Multi-Tennant <param name="presence-privacy" value="false"/> SIP Trace for Subscription FS Receives this from the phone: SUBSCRIBE sip:203 at xxx.mydomain.com <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users>:5060 SIP/2.0 Via: SIP/2.0/UDP 192.168.1.24:25060;branch=z9hG4bK991003231;rport From: <sip:201 at xxx.mydomain.com <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users>>;tag=946578510 To: <sip:203 at xxx.mydomain.com <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users>>;tag=nvqzSrr57RZg Call-ID: 968288340-25060-7 at BJC.BGI.B.CE <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users> CSeq: 20050 SUBSCRIBE Contact: <sip:201 at 192.168.1.24 <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users>:25060> X-Grandstream-PBX: true Max-Forwards: 70 User-Agent: Grandstream GXP2140 1.0.5.29 Expires: 480 Supported: replaces, path, timer, eventlist Event: dialog Accept: application/dialog-info+xml,multipart/related,application/rlmi+xml Allow: INVITE, ACK, OPTIONS, CANCEL, BYE, SUBSCRIBE, NOTIFY, INFO, REFER, UPDATE, MESSAGE Content-Length: 0 FS Sends this back to the phone: SIP/2.0 202 Accepted Via: SIP/2.0/UDP 192.168.1.24:25060 ;branch=z9hG4bK991003231;rport=59364;received=x.x.x.x From: <sip:201 at xxx.mydomain.com <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users>>;tag=946578510 To: <sip:203 at xxx.mydomain.com <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users>>;tag=nvqzSrr57RZg Call-ID: 968288340-25060-7 at BJC.BGI.B.CE <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users> CSeq: 20050 SUBSCRIBE Contact: <sip:203 at y.y.y.y <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users>:5060> Expires: 480 User-Agent: Callstera VOIP PBX v1.20 Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: timer, precondition, path, replaces Allow-Events: talk, hold, conference, presence, as-feature-event, dialog, line-seize, call-info, sla, include-session-description, presence.winfo, message-summary, refer Subscription-State: active;expires=480 Content-Length: 0
