[Asterisk-Users] something between an ATA and a channel bank for a small office?

[nik martin]

I have had very bad experiences with IAXYs so far.. I have pulled them 
and will be attempting a refund shortly.  Bad audio, overheating and 
shutting down until allowed to cool, etc. make it unusable in a business 
environment.

That said, is there a low-mid priced solution for a remote office to 
connect to a home office runing asterisk?  There seems to be a hole in 
the market for 6-8 person remote offices.  SIP isn't really an option 
because the remote office is fairly low bandwidth (1.4 mb down, 256k up 
ADSL).

It seems my options are:
1. Inexpensive SIP phones connected to a local asterisk server which 
connects to my * server at the main office.

2. POTS phones + Asterisk + channel bank + t-1 card at remote office, 
connected to my asterisk server at main office

3. POTS phones and multiple FXS cards in * server at remote office with 
local T-1 line to terminate calls + IAX2 connection to main office for 
inter-office calls.

None of these seem ideal due to the complexity of having a remote * 
asterisk server in the loop.

Any suggestions?
