I have an Avaya 4602 IP phone that was previously working with Asterisk. It
was being used elsewhere for several months, and I recently set it up again
to work with Asterisk. Everything works fine for several minutes -- I am
able to receive and make calls as expected. However, after a few minutes,
and every few minutes thereafter, I get the following message on the
console:
-- Got SIP response 481 "Call Does Not Exist" back from 192.168.1.98
After this message, the phone no longer works properly -- if at all. When
attempting to dial, the phone seems to ignore my dial plan, accepting no
more than five digits (I get the tone burst indicating that it is done
accepting digits), and it does not transmit anything to Asterisk.
Attempting to call the phone's extension results in a busy condition (SIP
response 486). Soft resetting the phone restores it to working order for
several minutes.
I have searched Google and the Wiki for answers to this problem, and see
that Brian Elton has experienced this exact situation. However, I saw no
resolution posted to the list, and do not have Brian's contact information.
I suspect this may be related to the MWI indicator and the "mailbox="
statement in my sip.conf file, as the last time I was using this phone with
*, it was not set up to use voicemail.
Any ideas or assistance will be greatly appreciated.
Sincerely,
Trevor Hammonds
