sundance-communications.com/forum Forums TDM Business Telephone Systems Avaya - Lucent Telephones & Systems SIP and IP Office? IP Office and softphones?

I have a few questions for anyone who can help.

All of this I have googled heavily for, but am unable to find definite info.

1. Does Avaya's IP Office 403 support SIP?
2. How do you go about setting up a Softphone on IP Office?
3. Using a SIP ATA (Analog Telephone Adapter) can you run a fax machine via a VOIP system?

I've been tearing hair out on this for a few days because I cant find any hard info, and for some reason I just cannot get a softphone to work on my IP Office 403 installation.

Any help or howtos someone can point me to would be most apprecaited.

Thanks in advance

Well, i posted too soon. I have found that IP Office vers 3.0 and earlier (all that are out now) do not support SIP. And that over a Cisco ATA 186 you can fax as long as the network is good. So, two of my questions are done, and a new one is added.

Does anyone know if there is anything special needed to configure a Cisco ATA 186 (running h.323) on an IP Office 403? :-)

Thanks
