I should also say we are using "modem pass-through" for the fax transmissions over ip.

We send fax transmissions over sip trunks every day. As long as the codec is locked at 711, we usually don't have problems with the Cisco ATA's. The credit card terminal is kind of new to us. Not sure if something needs to be tweaked for it to work correctly. We did disable silence suppression, which is a default setting.

You would need gateways that support MoIP (Modem over IP... v.150 I think). And you won't be able to bring them in over a SIP trunk. This would only be gateway to gateway and sketchy at best.
