[asterisk-users] ATA recommendation??

[Oguzhan Kayhan]

Hello,
I want to ask that if thee are some ATA decives that i can use to connect
mutliple analog phone lines to my VOIP system..
I mean for example an ATA device with 24 ports with 24 independent SIP
accounts.

For example for some dormitories in my area, i want to put an ATA device
and move existing lines to VOIP accounts.
Only problem is, if i dont give seperate SIP accounts for all ports, i can
not control who is calling where... And the billing system will also be a
problem in that case.

Tnx...
