This attribute indicates how this SwitchedVoiceService negotiates with V.17 fax machines, as determined by negotiation with the remote end across the subnet. The parameter used for negotiating with the remote end is provisioned in Vncs Vp v17EncodedAsG711G726.

If negotiatedV17AsG711G726 is no, V.17 fax machines are instructed to use V.29, and V.29 fax traffic sent by fax machines is demodulated and encoded using fax relay.

If negotiatedV17AsG711G726 is yes, V.17 fax machines are permitted to use V.17 and V.17 fax traffic sent by fax machines is encoded using G.711 or G.726, at the rates given in negotiatedRates.
