I have discovered something that seems to be backwards. When pressing flash to end a three way call Between me, "Party A" and "Party B", Asterisk will drop "Party A" instead of "Party B". My Telcos version of three calling will drop "Party B" when ending the three way call. In my testing, "Party A" is a sip client and "Party B" is a call out through the PSTN. "Party A" is the first extension i dialed. "Party B" is the second extension i dialed after press flash to start the three way call. Any ideas ? Thank you, Steve Maroney
