Anyone use HotCall or ComSwitch 5500 [or something similar]?

[preCRT]

Do they work?

I need a device that will allow calls while online. We already have 2 phone lines, but now there are 2 people using dialups at the same time. Already have call waiting on one line, call forwarding on the other.

Does anyone have HotCall or ComSwitch [made by Command Communications] or any other phone/modem device that will allow calls through?

It would be great if it allows outgoing calls. But I'd be minimally satisified with incoming calls.

Any ideas?

Thanks.
