Our healthcare company sends out ~35,000 faxes/month and is in the process of fully converting from faxing over analog phone lines to the SRFax service. We are 1-month into the conversion and everything is going very well for us. We've had a few phone routing issues, but the SRFax support team has been very responsive to assist us with correction. Overall, we are extremely pleased with the service provided and I would definitely recommend SRFax to anyone requiring a fax solution.
