Greetings,

My company makes a TDM based dialer/IVR. We have been getting a lot of requests lately for SIP trunk connectivity due to the carriers charging much higher fees when dialers are used on a TDM network. In order for us to natively do this there is some programming and hardware changes needed. In the meantime I would like to offer my customers a gateway so that they can connect to a SIP service provider.

I would like some recommendations on gateways that can provide between 4 and 16 T1/PRI ports, is easy to setup and maintain.

If anyone has questions or suggestions I welcome those as well.
Thanks,
Dave
