[cisco-voip] rural setup

[Karthikeyan Arumugam]

dear list,
iam setting up a rural telephony through WLL.

Since Ckt switch system is costly, iam thinking of my own Wireless setup
with low cost
BS  and Clients with IP in 2.5Ghz. So i would like to make few points
clear...

1. i connect my Switch to FXO gateway and extend IP thrrough wireless - and
client with Ip Phone.
So, in this case is it possible Ip phone discuss with FXO gateway and make
outgoing calls of the PBX.
is the setup be possible ???

can i use different vendor ip phone and Fxo gateway.

looking forward lists comments

thanks
karthi
