Authentication verification phone call no audio

Jason Beckett 6 Reputation points

I have users that are trying to use the phone verification method. Their VOIP desk phone rings but then there is no audio. Seems odd to me that the call works to their cell phone but dead error on their desk phones. Is there some incompatibility with doing the verification call to voip lines?
