I have a SPA2102 connected to my PIAF box, but it seems to go into a funny state at least once a day. When it gets in this state, calls from my inbound trunk is not routed to this device. Callers receive the message that the number is not valid.
It appears that the call is arriving since FreePBX will show an active channel when the incoming call is made. Also, if I call the SPA2102 device using another phone on the LAN the call goes through. It is only after resetting the SPA2102 are calls routed properly from the inbound trunk.
My inbound trunk is Callcentric and the SPA2102 configuration details are (from sip_additional.conf):
If anyone has any ideas what the problem might be, please tell me. Currently, I have to reset the SPA2102 every morning to make sure I get calls during the day.
