[Asterisk-Users] GXP-2000 phones stop registering

[Gareth Blades]

I have about 30 GXP-2000 phones running 1.0.1.9 which have all been
configured using the provisioning feature so the configuration is all
identical.

The problem I am having is that they randomly seem to stop registering
with asterisk. When they stop registering they can still make calls but
oviously asterisk cannot ring the phone so all incoming calls go to
voicemail.

Has anyone else had similar problems?

example sip.conf entry:-

6015]
type=friend
secret=xxxxx
username=6015
callerid="users name" <6015>
host=dynamic
nat=no
canreinvite=yes
disallow=all
allow=ulaw
allow=alaw
deny=0.0.0.0/0.0.0.0
permit=10.0.0.0/255.0.0.0
context=voipuk
mailbox=6015

The phone config is fairly standard. the registration expiry is set to
60 minutes
