[Asterisk-Users] PSTN Incoming call on real line disrupts VoIP call over DSL circuit - EXPLAINED

[Andres]

Forget about the static IP from BS.  They only provide that to business 
accounts.  But now that you know the problem it will be easy to explain 
it to BS and have them take a look at it.

There could be something wrong with the wiring in the house.  Maybe a 
short which causes a signal spike when the call is answered and 
interrupts the PPPoE session.
