Answer

Have a look at the SIP NOTIFY Asterisk is sending to the phone, delivering the voicemail status. In that NOTIFY message Asterisk is adding a SIP URI which is used by the phone for retrieving the message (calling the mailbox). Most probably in your case the SIP URI is not correct. Do you have already set up the following in your Asterisk?

Example

  • sip.conf:
mailbox=100
  • extensions.conf:
exten => asterisk,1,VoiceMailMain(s${CALLERID(num)})
  • voicemail.conf:
100 => AM100


The NOTIFY sent from Asterisk informs the phone about how many messages are waiting and the voice mail extension to call:


NOTIFY
...
CSeq: 1 NOTIFY
...
Subscription-State: terminated;reason=noresource
Content-Type: application/simple-message-summary
Content-Length: 90

Messages-Waiting: yes
Message-Account: sip:mailboxextension@your_asterisk_domain
Voice-Message: 2/0 (0/0)

The phone recognize this message:

SIP/2.0 200 Ok
...
CSeq: 1 NOTIFY
Content-Length: 0
