Its fixed now but why wouldn't you just drop all PIC codes instead of generate an error?

It is hard to say, but likely they didn't account for 10-10 codes in the dialing plan. My Yealink phone used to send 11 when I tried to dial any extension that started with 11 (ie.. ext 112). The dial plan didn't account for anything starting with 11.
