And, in the config, I also see...

ephone-dn  2

number 801

label Fax

description Fax

name Fax

hold-alert 30 originator

This is going to cause a problem.  ephone-dn 2 should not be 801.

Should I remove ephone-dn 2?

Yes, you should definitely remove ephone-dn 2, or change the number.

I removed the ephone-dn.

I changed the path of the flash.

It is still not working.

If you change the location on flash, it will require a reload of the router for the script to load.  You must do that as well.

After that, if it is still not working, post another debug.

After reload, still no luck.

Can I run any other helpful debugs in addition to debug voip dialpeer?

Here is an example for you that I have created.

Here is one suggestion, after you type fax interface-type fax-mail.. CME must be reloaded..  So restart as well... Also some inbound dial-peers in the configuration like to answer even though these commands below work... so you have to "debug voip ccapi inout" and watch to see what dial-peer is answering... then copy it from CLI and then delete it and then test...  Make sure to copy all the dial-peers so you can paste them back in..  the order of the dials-peers matter as well from top to bottom..  almost like an access-list..

FAX to EMAIL on UC500 using analog line - CONFIGURATION EXAMPLE

**Please note this is for Analog lines. PRI will work as well but you do not have to PLAR from the FXO ports. Also make your incomming called number and destination pattern matches the number exact;y from your ISP (i.e, some PRI's only send 3 or 4 digits not the whole 10 digit number)

1) You have to download and application from Cisco's website. It is under Voice Products.

app_faxmail_onramp.2.0.1.3.tcl
http://www.cisco.com/cgi-bin/tablebuild.pl/tclware

Load this file onto the FLASH of your UC500 using TFTP and "copy tftp flash" command.

** Load the application with the following commands.. **

application
service onramp flash:app_faxmail_onramp.2.0.1.3.tcl

In global configuration mode of UC500 type the following: (Not all are needed)

I struggled with this for a week.  Every config I tried did not work.  It ended up adding one command made it start working.

tftp-server flash:app_faxmail_onramp.2.0.1.3.tcl

I will also attach a config example I got from TAC when I setup it up on another box awhile ago.  I think if you use a combination on those config lines along with the guide from Marcos for the CUE pieces, it should work easily.
