Can I fax over SIP?
Yes, most SIP providers support G.711 or T.38 faxing protocols. We’ve been told that faxing over SIP trunks is about 95% reliable. For this reason, we generally recommend that our customers keep faxing off SIP trunks and on analog lines (which is great for a back-up line anyway). This may change as we feel more comfortable with it.
