Note: Using diversions on fax to e-mail numbers is not supported.
When using a diverted number for your inbound faxing, you may experience an unusually high number of errors and failures. This applies to any kind of redirection, including exchange-based redirection and VoIP redirection from 3rd party providers.
These errors may include but are not limited to:
- The call dropped prematurely
- Various negotiation errors
- Protocol errors
The issue is caused by the increased latency introduced into the call channel by a diversion. Faxing is a very latency-sensitive technology and the extra few hundred milliseconds of delay introduced by a diversion can completely break the negotiation and communication process.
For this reason, we do not support using diverted numbers for faxing.
There are two possible resolutions to these issues:
- Port the diverted number to us, so it can be attached directly to your Fax to e-mail service (removing the latency)
- Discontinue using the original/diverted number and use the direct number associated with the service instead (the number you were diverting to)
