[Asterisk-Users] Asterisk in a rural project

[Jorge Mendoza]

We have working in a rural project and I have selected Asterisk. Because 
* will work with a prepay system we need a precise answer supervision 
for outgoing calls. The pilot system will have 8 trunks to PSTN. The 
Telephone Company provides EURO BRI and analog CO trunks. On CO trunks 
the answer supervision is reversal polarity. The village to be served 
will be connected through a WLAN. Thus, the two scenario will be:

1.- PSTN <----> [BRI SIP Gateway] <------>[Radio Link 802.11b] <-----> 
[Asterisk] <----> SIP Phones + FXS
2.- PSTN <----> [Asterisk + Channel Bank] <----->[Radio Link 802.11b] 
<----> [Asterisk] <---> SIP Phones + FXS

In point 2 the channel bank has FXO with reversal polarity detection.
Initially, the system and users will have a few features as possible: 
Automatted Attendant, VM, outgoing dialling an answer calls (probably 
blind tranfer).

Are these approach correct? Any issues?
