VOIP line sharing using a Fax Switch

Rama

I am planning to get a Clear VOIP line to replace my landline which I use for both voice and fax calls using an automatic switch from Command Communications. Incoming calls are picked up and the switch rings the fax machine if it hears fax tones. Else it rings the telephone. This way, I did not need a separate telephone line for the fax machine.

I want to know if anyone has successfully used a switch on Clear voip line to achieve the above sharing.
