Does call-waiting work for anyone that recieves 2 pstn calls on a X100P using a Sipura? I have modified the dialplan in the Sipura such that the *0 is definately getting sent to the Asterisk server now. When the phone beeps and I flash hook I get tone, then dial *0# and the sip debug shows that *0 was acknowledged but I get a rapid busy back from Asterisk.
