This may be far too out, but I'd like to make the PRI channel states 
dependent from SIP channel states. So that the SIP PING monitoring 
thread could trigger PRI state changes. That would make it possible to 
signal SIP connectivity issues to the PRI service provider, which in 
turn could route incoming calls to a redundant PRI/asterisk gw (PRI 
roll-over).
