Asterisk Fax

Asterisk Asterisk Support
1

Today I downloaded and installed the new Digium Fax for Asterisk modules… res_fax and res_fax_digium.

Fax detect is working on my analogue TDM410P card however the ReceiveFax function doesn’t work and I always get an error…

[Apr 9 06:59:03] WARNING[14532] frame.c: Smoother was working on 4 format frames, now trying to feed 64?
[Apr 9 06:59:03] ERROR[14532] res_fax.c: channel ‘DAHDI/1-1’ fax session ‘0’ failure, reason: ‘Failed to feed the smoother’

I realise this module is pretty new so could be buggy but was wondering if anyone had any solutions regarding this error.

Thanks

I can’t help you as I haven’t used Fax for Asterisk yet, but I intend to, so I would be interested in your experiences with it. Since it is a commercial product, you should be able to get support from Digium.

Hi

I’m using SendFAX and ReceiveFax in 2 companies without problems over SIP trunk. In sip.conf I have “t38pt_udptl = yes” and all calls are with alaw. Check for simular option in chan_dahdi.conf

I just tried to install FAX and getting the same error.

Hi,

Was anybody successful making it to receive faxes on PSTN lines?

Running AsteriskNOW 1.5

FreePBX 2.5.1.5

Asterisk 1.6.0.9

Getting “Smoother was working on 4 format frames, now trying to feed 64?”

Any ideas, thoughts?

Thank you,
Vladimir
