[Asterisk-Users] X100P random hangups - Please help with suggestions

[Vassilis Konstantinou]

Just to answer my own question so that this loop is closed and hopefully 
others who suffer from the same problem may find this useful.

The problem in the end had nothing to do with Asterisk of the X100P or at 
least not directly. After pulling my hair for months and checking various 
bits of code, drivers and hardware, I realised that the problem was cause 
by a stupid desktop digital satellite box (UK SKY)connected in parallel 
(well ...same line other socket) with the X100Ps. The box has a modem and 
has to phone 'the mother ship' every so often for billing purposes  mainly. 
God knows what it does to the line in between but my suspicion is that the 
combination of impedance of the two was the main cause of the random 
hangups.  As soon as I removed it from the socket, the problem disappeared! 
So if you get random hangups with X100Ps and you have other devices 
connected directly on the main line, check those as well.

Many thanks to all the people who contributed ideas.
