cat3 will do 10bt, YMMV based on the install job and length of the runs, but for qaulifying the lines there is a simple one word answer, pentascanner. I've got one, if the job is in the sf bay area you can rent me for a day.

I'm staring at an RFP--this company wants to replace a 2000 position PBX (at eight locations) with a new system. Their mindset is Nortel/Avaya because they talk about 28-button digital sets. The do specify a few IP phones for just one location, so they are aware of VoIP.

I'm going to bid on this--there's nothing to lose except the time it takes to write the proposal. I'll bid an off site Asterisk system with SIP telephones. Using the metric of 100 SIP phones/box, I'll bid twenty Asterisk boxes with ten boxes at each of two hosting locations. Each phone will have registrations to both sites.

The big unknown is wiring. I'm going to assume the worst, that the existing LAN is overloaded. I would a) have to make LAN wiring out of existing Cat3 wiring, or b) install a new voice-only LAN.

Does anyone know how to qualify existing Cat3 wiring for use as a LAN?

Has anyone does an Asterisk system on this scale?

Thanks for your help,
Mike

P.S.  Sorry for the cross post, but I would like everyone to see this.
