We have 2 T1's coming into a voice gw. One is connected to telco via a pri for outbound calls. The other is connected to a IVR system via a T1 Cas e&m. The IVR is setup of to send faxes out and a dialpeer is setup to send these faxes to the PRI. Non Fax calls work fine for transfer..but Fax calls fail. I have noticed that on a transfer call the codec is negotiated @ g711 but the faxes have a codec of None. Is there something I am missing...these calls are non voip and a dsp is not used for the call...please advise.
