Hi all,
We recently got a requirement from a client that needs a door phone that will work with the SIP PBX that we recently installed. I came across the product below for a SIP door phone from Valcom, but I can't find any documentation on Valcom's site.

Does anyone have good experiences with a door phone that works well with SIP PBX's, preferably with some decent documentation on the web and native SIP vs. using an FXS or FXO and connecting to an analog door phone.
We have had great results with conventional Viking POTS door phones connected to an FXS port on an Adtran TA9xx or an ATA. Only one pair needed, no problems with long PoE ethernet loops to a pedestal at the end of the driveway, etc. Substantially less money than the SIP products especially if you have an analog port available. This may change as they are made in greater quantities down the road. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
