[Asterisk-Users] Not a User Yet - but have some questions

[Peter Harrison]

I've been tasked with fitting out an appartment building with a phone system. 
The entire appartment is getting broadband, with Cat6 Cables into each 
appartment and fibre down the trunk. I was hoping to have PSTN in the 
basement connecting to the IP system.

Today I found out however that one of the services will be paid TV - and it 
will need a PSTN backchannel - ie a modem. The set top devices don't support 
IP, they have modems built in, and I don't believe they are willing to 
provide an alternative. Also, the tenants may wish to call IP services via 
modem, or use a Fax.

My question: Can you run modems/Fax over VoIP?
