AMA-CUCM Troubleshooting: Best Practices for Reading Trace Files


UC560 Fax rate question.

I have set up fax to email on my UC560, though recently switched vendors for our telephony service.  I thought it was going to be a straigh pri-pri switch, but it was not.  I'm being asked to set my system to receive at 9600bps.  Is there a way to do that in the UC500 series?

I had previously set up my uc560 to do fax to email, sample config here with one of the did dial peers:


fax receive called-subscriber $d$

fax interface-type fax-mail

mta send server port 25

mta send with-subject both

mta send mail-from hostname

mta send mail-from username $s$

mta receive aliases

mta receive maximum-recipients 7



service cca_fax_detection flash:/applications/faxmail/app_fax_detect.

  param fax-dtmf 2

  param mode listen-first

  param voice-dtmf 1

  param prompt flash:/applications/faxmail/


service cca_offramp flash:/applications/faxmail/app_faxmail_offramp.


service cca_onramp flash:/applications/faxmail/app_faxmail_onramp.




dial-peer voice 3016 pots

description 5017_T37

translation-profile incoming 5017_T37_Called_21

service cca_onramp

incoming called-number 5017


port 0/3/0:23

translate called 21

I don't think one can set speed for receiving in T.37 mode. Can you please post "show controllers T1".

So it seem network-clock is set right... You should be able to receive fine.


UC560 Fax rate question.

Faxes to the DID's that have the service cca_onramp don't work.  The UC picks up the call, and sends negotiation tones, but we can't receive.

Can you take some debugs. I think these are of the form debug mta, but do not have reference here. It is actually quite difficult to find fax debugs commands, but you can start checking if it is an email problem.
