Fax OnRamp Issue


I did the following configuration:

hostname Router

ip domain name infomicro.local

ip name-server

fax receive called-subscriber $d$

fax interface-type fax-mail

mta send server port 25

mta send subject "Cisco FAX to Mail"

mta send postmaster nelson@infomicro.local

mta send mail-from hostname Router.infomicro.local

mta send mail-from username $s$



service fax-onramp flash:app_faxmail_onramp.


interface GigabitEthernet0/1

ip address

duplex auto

speed auto


dial-peer voice 40 pots

service fax-onramp

incoming called-number 5551234



dial-peer voice 41 mmoip

service fax_on_vfc_onramp_app out-bound

max-conn 5

destination-pattern 5551234

information-type fax

session target mailto:fax@infomicro.local

When I make a call to the 5551234 the call begin the ring and after 2 or 3 seconds the call is answered, but that is all, the fxo port where I'm connecting the incoming line bring up and immediatly close the channel, I mean, disconect the call.

My question is, what is wrong? what I'm forgetting?

Hope somebody can help me



PS: sorry about my english

Re: Fax OnRamp Issue

Hi Nelson

I haven't checked all your config but you're missing a POTS dialpeer to the FXO port. The FXO voice port should also have the "signal did" command because DID is not enabled by default (as far as I know).

Re: Fax OnRamp Issue


I'm using a Cisco 3825 with Cisco Internetwork Operating System. Cisco IOS (tm) C3825 C3825-ADVIPSERVICESK9-M, The System version is 12.4(15)T7 / CME 4.1(0) and I try to configure a "T.37 Store and Forward Fax" but when I download the latest version of tcl script ( and and I put it on my router cannot do anything!!!.

And when I check how to solve this problem I found when I put in the CLI the command: "sh call application voice onramp_kywi" (onramp_kywi calls the script only have the next response:

Script Name : onramp_kywi

URL : flash:app-faxmail-onramp.

Type : Service

State: Not Loaded

Life : Configured

Exec Instances: 0

Script Code Begin:



The same thing ocurs with the offramp script.

The most "worrying" part is when the command says about the script "State: Not Loaded"

Do you have any fix/solution to this problem???...I need urgent help.

You need to reload the router to load the script.
