Fax CNG being detected by trunk but reception errors out

Hi there,

I have FreePBX 17 setup, updated and working fine for calls. I decided to setup incoming fax, but having the following errors when attempting to receive a fax.

NOTICE[21910][C-0000000c] chan_pjsip.c: FAX CNG detected on ‘PJSIP/voip_sip-0000001f’ but no fax extension in ‘dial-with-exten’
NOTICE[21910][C-0000000c] res_fax.c: FAX CNG detected but no fax extension in context (dial-with-exten)

I’ve set “Fax Detect” to yes on the trunk.

I’ve set “Detect Faxes” to yes for the inbound route and set the "Fax Destination “Fax Recipient” for the account that I created to receive the fax.

But I always get the error listed above when a fax comes in.

If I answer the call and manually transfer it to the fax extension I created, the fax is received successfully and I get an email.

Can someone help me bridge the gap to get the call routed correctly when fax cng is detected?

Cheers.
