To make sure it wasn't a phone compatibility issue, I brought a Snom 320 (That works at the office on the same subnet and uses the same gateway) to my home office and I can dial number just fine, just no audio what so ever, either way.
I attached a log file of trying to dial *97 from the phone.
If it helps, the other problem we are having is that call parking does not work. I put a call on hold and dial *85"send" and it says call parking has failed.
Thank you,
