Extension Problem

When I try to dail someones extension the operater comes on and say “the person at this extension is on the phone please leave a voicemail after the tone.” Nobody can dail anyones extension because this keeps happening, any suggestions.

Sorry to hear you are having the same problem. Look at http://forums.digium.com/viewtopic.php?t=1382 and you will see you are not alone.

First question I have for you is what is the specs of your hardware? Are you using SMP server? What OS are you using? What other software do you have installed alongside Asterisk (AMP?).
