Faxing over VoIP (Tech Note)

Faxing over VoIP (Tech Note)
Symptoms: Failed fax transmissions


Resolution (Permanent):

AltiGen does not currently support or recommend the use of FAX machines over VoIP connections (FoIP, T38). Because of the possible delay of packets, the initial fax machine setup and handshake will fail. If you would like to test faxing over VoIP in your environment, make sure you're using G.711 and latency between servers is as low as possible (<5ms).
