Which VoIP protocols and which codecs do you support?
At the moment, Flowroute only supports SIP for signaling.
- Supported media codecs are G.711a /G.711u and G.729.
- Flowroute also supports T.38 standard. We process it with no extra requirements beside what would be required for a Flowroute voice line, and your destination supporting the same protocol.
- Please contact your fax equipment provider if you are unable to complete a fax with quality audio on the voice line.
