Hi, I've got trouble with calling from IP extension on one ELU 32 to another ELU 32 (MD110 BC12.8). Tverything is fine (I mean ringing), but if B-party pick up the line, there is absolutely quiet on both sides. If one of them hung up, the call is normally canceled. Does anybody know, what's the wrong? If the call is through one ELU 32, there is no problem... Thanks
