I know how to fox this with an asterisk install but cant seem to find what i need in the sip conf files on freepbx.
Basically Avaya phones unregister from asterisk occasionally , it is due to Avaya using a non standard MWI i believe :
Looks like this
[2014-02-07 10:32:41] VERBOSE config.c: == Parsing ‘/etc/asterisk/rtp_custom.conf’: Found
[2014-02-07 10:32:41] VERBOSE res_rtp_asterisk.c: == RTP Allocating from port range 10000 -> 20000
[2014-02-07 10:32:44] NOTICE chan_sip.c: Peer ‘7002’ is now UNREACHABLE! Last qualify: 96
[2014-02-07 10:32:45] NOTICE chan_sip.c: Peer ‘7001’ is now UNREACHABLE! Last qualify: 48
Anyway fix on asterisk is to remove the mailbox=xxxx@device line from sip.conf.
I cannot find where i would do this on freepbx as the sip.conf just links to other conf files that dont seem to have that line!
Any help appreciated!
