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...
Grandstream makes an 8-port unit which we've had success with, you could use three of them.> 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...

I would suggest Audiocodes, Vega, or Carrier Access as starting points. Yes they come in 24 and 48 port versions.
