Jegavelan Hi, do you see iax peer registered? (iax2 show peers)
If not, set requirecalltoken to "no" and check your firewall rules.

Regards.

Jegavelan

Shows IAX extension one registered

Jegavelan

any advice ?

Check that Virtual Fax List shows status Running and idle on ttyIAX1?

When receiving a FAX that status will change to something like Receiving Fax on HylaFAX...

In your IAX2 fax extension set requirecalltoken = No

Check that HylaFAX is running systemctl status hylafax

I just faxed myself something and it worked for me. Viewable as PDF in Fax Viewer.

From Asterisk console asterisk -vvvr
This was the last part as the fax was coming in and going to my IAX2 extension # 900

-- Goto (macro-dial-one,s,43)
    -- Executing [s@macro-dial-one:43] Dial("SIP/voipms-la-00000009", "IAX2/900,,Ttr") in new stack
    -- Called IAX2/900

Make sure that the requirecalltoken option is set to no, before trying to register a virtual fax.
If you don't do this, the extension will not register and thus not accept any calls.

Jegavelan

Check that Virtual Fax List shows status Running and idle on ttyIAX1?
Yes showing the same

When receiving a FAX that status will change to something like Receiving Fax on HylaFAX...
Never received anything so far so no way to check it.

In your IAX2 fax extension set requirecalltoken = No
Yes set to No

Check that HylaFAX is running systemctl status hylafax
Active: active (running)

I dont see anything in the logs saying about the fax extension. below are the logs at the time of the fax

That looks to me like it is not detecting a fax. Shortly after the "FAXOPT(faxdetect)=yes" line you should see

 == Redirecting 'SIP/voipms-la-00000001' to fax extension due to CNG detection
 == Spawn extension (ext-did, fax, 1) exited non-zero on 'SIP/voipms-la-00000001'
    -- Executing [fax@ext-did:1] Goto("SIP/voipms-la-00000001", "from-did-direct,900,1") in new stack
    -- Goto (from-did-direct,900,1)

Is your SIP trunk set to receive ulaw codec and are you sure your SIP provider works with ulaw fax?

Have you tried a different SIP provider? I know it works with voip.ms

Jegavelan

This is my inbound setting looks like below

It is not detecting a fax signal. So that is most likely a problem with your SIP trunk. Try set the trunk codec to ulaw only and check other trunk settings. Confirm with the SIP provider that your DID number can pass fax on ulaw. Otherwise try a different SIP provider.

Jegavelan

this what I have in sip configuration
[root@JSJPBX asterisk]# pwd
/etc/asterisk
[root@JSJPBX asterisk]# cat sip_additional.conf

That looks like they are using a Google Voice gateway. I have my doubts that fax will work for something like that.

Jegavelan

It should work I am using the same locally and it works fine without any issues.

supa

Everything just works for me. Including receiving faxes from Google Voice/Chan Motif trunk.

I would try a different SIP trunk provider as a sanity check.

Jegavelan

Finally I got it worked but end with different error now
