If your provider supports T38, you'll have no problem (or almost no problem).
On the opposite, you cannot base a production fax system on pure G711 analog transmission, you'll have too many failures if you are not on a perfect network endtoend (fax has audio and timing requirements much much more strict than voice transmission).

We are doing analog fax with voip.ms as a provider using CISCO/Linksys ATAs and we have a pretty good success rate (sending and receiving). I can't give you an exact percentage, but it is rare that we have a fax totally fail. Sometimes it takes an extra attempt to get it to go through.Hope that is helpful.JasonOn Wed, Aug 19, 2015 at 8:47 AM, Michael T Mowatt <mmowatt@nexxphase.com> wrote:HI all,
Was wondering if anyone is using FreeSWITCH to receive faxes over a SIP trunk, and what the experience has been like. I know I’ve heard this can be difficult, but was interested in real experiences.
Thanks,
Mike
