Inbound fax pickup

[karshah]

We have a 2nd NexVortex DID hitting our 3cx version 5 box. This number is for faxes only. 3cx sees the incoming call and directs to the 888 fax box. That's about it. It disconnects with the following error:

[CM503003]: Call(116): Call to sip:[email protected]:5060 has failed; Cause: 404 Requested user not found; from IP:192.168.7.8

This was preceded by audio codec negotiation issues. Any advice would be very appreciated.

Thanks and hope your New Year has started off well.

First suggestion would be to direct that number to a regular extension, then call it. Would establish if a general setup issue or specific to the fax extension.

Routing to extension

Routing to an extension works. Sound quality very good. I'm using G711.
