configure dial-peers for fax T.38 in Cube

[monasir]

I'm trying to send out faxes from a fax server ( Xmedius )

However i'm not able to send it out via the cube to the service provider

The fax is based on t.38

It should send in this way.
Its not working

Xmedius =====> Cube===== > ITSP

How can i get the fax send out properly?

Appreciate all the help

Hello,

Configure your inbound and outbound dial peer with below config to enable T.38 on CUBE

dial-peer voice <tag> voip
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback pass-through
fax-relay ecm disable
fax-relay sg3-to-g3
no vad

If fax calls still fail then collect "debug ccsip message" and "debug voip ccapi inout" logs and share it.
