I have captured the SIP packets for my VTech VSP 735. After the subscribe succeeds, I get a NOTIFY from FreeSwitch to the Phone that includes " Messages-Waiting: no". Can anyone tell me why? Or better still tell me how to enable MWI for this terminal. I went to the docs the parameter suggested. Below is a partial sip dump and the Directory entry for the phone. Any help would really be greatly appreciated. ------------------------------------------------------------------------ recv 476 bytes from udp/[71.121.214.88]:1026 at 16:33:39.074823: ------------------------------------------------------------------------ SUBSCRIBE sip:223@66.241.102.41:5060;transport=udp SIP/2.0 Via: SIP/2.0/UDP 71.121.214.88:1026;rport;branch=z9hG4bK673363934 From: <sip:223@66.241.102.41<sip:223@fs_bfis.bizfocused.com>>;tag=1645429613 To: <sip:223@66.241.102.41<sip:223@fs_bfis.bizfocused.com>>;tag=N3se6oVe4v7B Call-ID: 153343976 CSeq: 25 SUBSCRIBE Contact: <sip:223@71.121.214.88:1026> Accept: application/simple-message-summary Max-Forwards: 70 User-Agent: Vtech Vesa VSP735 1.0.3-0 Expires: 600 Event: message-summary Content-Length: 0 ------------------------------------------------------------------------ send 727 bytes to udp/[71.121.214.88]:1026 at 16:33:39.076436: ------------------------------------------------------------------------ SIP/2.0 202 Accepted Via: SIP/2.0/UDP 71.121.214.88:1026;rport=1026;branch=z9hG4bK673363934 From: <sip:223@66.241.102.41<sip:223@fs_bfis.bizfocused.com>>;tag=1645429613 To: <sip:223@66.241.102.41<sip:223@fs_bfis.bizfocused.com>>;tag=N3se6oVe4v7B Call-ID: 153343976 CSeq: 25 SUBSCRIBE Contact: <sip:223@66.241.102.41:5060> Expires: 600 User-Agent: FreeSWITCH-mod_sofia/1.2.22+git~20140309T212137Z~65fed130e5~64bit Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: path, replaces Allow-Events: talk, hold, conference, presence, dialog, line-seize, call-info, sla, include-session-description, presence.winfo, message-summary, refer Subscription-State: active;expires=600 Content-Length: 0 ------------------------------------------------------------------------ send 913 bytes to udp/[71.121.214.88]:1026 at 16:33:39.103860: ------------------------------------------------------------------------ NOTIFY sip:223@71.121.214.88:1026 SIP/2.0 Via: SIP/2.0/UDP 66.241.102.41;rport;branch=z9hG4bKB1H0peQSN33gH Max-Forwards: 70 From: <sip:223@66.241.102.41<sip:223@fs_bfis.bizfocused.com>>;tag=N3se6oVe4v7B To: <sip:223@66.241.102.41<sip:223@fs_bfis.bizfocused.com>>;tag=1645429613 Call-ID: 153343976 CSeq: 2027115047 NOTIFY Contact: <sip:223@66.241.102.41:5060;transport=udp> User-Agent: FreeSWITCH-mod_sofia/1.2.22+git~20140309T212137Z~65fed130e5~64bit Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY, PUBLISH, SUBSCRIBE Supported: path, replaces Event: message-summary Allow-Events: talk, hold, conference, presence, dialog, line-seize, call-info, sla, include-session-description, presence.winfo, message-summary, refer Subscription-State: active;expires=600 Content-Type: application/simple-message-summary Content-Length: 73 Messages-Waiting: no Message-Account: sip:223@66.241.102.41<sip:223@fs_bfis.bizfocused.com> Directory Entry: <user id="223"> <!-- Seans Test Phone --> <variables> <variable name="outbound_caller_id_name" value="Sean"/> <variable name="outbound_caller_id_number" value="4439219427"/> <variable name="internal_caller_id_name" value="Sean"/> <variable name="internal_caller_id_number" value="223"/> <variable name="user_context" value="from-internal-BFIS"/> <variable name="user_originated" value="true"/> <variable name="toll_allow" value="domestic"/> <variable name="accountcode" value="BFIS"/> <variable name="mwi-account" value="223@voicemail_BFIS"/> <variable name="callgroup" value="1"/> </variables> <params> <param name="password" value="KEPTSECRET"/> <param name="manage-presence" value="true"/> <param name="manage-shared-appearance" value-="true" /> <param name="mwi-account" value="223@voicemail_BFIS"/> </params> </user>
