Q: Can I use this ATA with a Patton BRI Gateway to set up a t.38 session between then so I can get reliable faxing to a physical fax machine connected to the FXS port. Most ATA's only seem to have T.38 passthrough .



A: Hi Ian,

Yes with the OBI100 ATA using the gateway you will be able to set up a t.38 session for faxing to hardware.

Q: We have recently transferred 2 telephone lines to Comcast Voice Edge. We would like to be able to convert the digital data from one of the lines to analog so that we can connect it to our fax machine. Will the OBi100 work well as an interface to do this for us?

A: Yes the OBi100 is the correct device for this situation. I would contact Comcast Voice Edge to check if there will be any compatibility issues.
