Here's an option that some might consider, especially in light of the ongoing problems with virtually all small FXO interfaces....the Zultys 4x5 SIP phone. This SIP phone includes an onboard 4 port router wit QoS and an FXO interface. At point of introduction early in 2004 the FXO i/f was only used as a lifeline. The firmware setup allowed the suer to pass local calls to the FXO while passing all other calls to * via SIP. Alternatively, the phone could try SIP calling outboard before falling back to the FXO. However, about two weeks ago Zultys released firmware that makes the FXO available as a SIP reource to *. Calling coming in on the FXO can be routed to * for transfer or VM purposes. It's a little strange since we're accustomed to having the FXO/FXO i/fs on the server. However, you could bring the POTS lines to the desktops and into the 4x5 phones. Then have the call pass to * when required. BTW, the router functions such as DHCP etc can be defeated if desired. Also, the 4x5, unlike some phones, requires only one registration to support multiple call appearances. From on registration the 4x5 support 4 active SIP calls and one on the FXO, at the same time. Michael P.S. - I'm buying one of these from a friend who doesn't need his anymore. I had it on loan for a month back in the summer. It worked well with* but the FXO > * firmware was not yet available. -- Michael Graves [EMAIL PROTECTED] Sr. Product Specialist www.pixelpower.com Pixel Power Inc.
