Can someone offer suggestions as to what I can check to stop the following happening.
I have Asterisk setup and the SIP trunk registered with BT, everything appears OK I can make and receive calls. Then at random it seems callers get a destination equipment is turned off or unavailable announcement.
When I look in the logs I can’t see anything that suggests a problem though they are full of the following
chan_sip.c: Registration for 'XXXXXXXXXX@btsip.bt.com’ timed out, trying again
rebooting the server corrects the problem but eventually it re occurs.
Thanks in advanced
