Hi All, I was trying to test to send a fax to an international number. Here's the setup: FAX --> HT486 --> SIP PROXY --> GATEWAY --> PSTN --> FAX Unfortunately I haven't been able to do it, I read somewhere that fax uses G711 only, is this true? because our gateway provider uses only G729. does this mean I can't send fax via that gateway, because of the codec? So can i do this then, FAX --> HT486 --> SIP PROXY --> HT486 --> FAX i'll use G711 on both HT486. Hope anyone can help me. Thanks in advanced. Regards, Ron
