Using CUE as SMTP relay

Answered Question

Hello world...


I hope someone has an answer to this - i have gone through the CUE CLI documentation looking to config it up as an SMTP relay, and this idea does not seem like it will work.


System is UC540 on 8.6.5


I have a PRI with a DID block for the client - they want individual fax numbers for each person.  That part is easy enough.  They do NOT want to store it in their vociemail box.  They just want it sent to their email inbox.  They do not want to use the "listen" mode where fax and voice comes in on the same DID because the delay for the customer calling in is too great in their opinion.  This is fine.  I get it.


However I am having a dickens of a time using the CUE to send the emails based upon the DID to the user mailbox.  I am talking about configuring a separate ephone-dn and an account on the CUE for the fax email user.  when i go this route, The sending fax machine just hangs and never successfully transmits.


IF, however, I set the "mta send server" to my test-bench smtp relay by IP address, it all works.  Fax as email attachment comes through like greased lightning.


I try to do it via the extension and have CUE submit it out, things just hang.


IS THERE A WAY to configure the CUE to act as a simple SMTP relay for all things internal?


This is the config that works for me:

mta send server 192.168.110.25 port 25 <IP addess of my bench smtp server>

mta send server 10.10.10.1 port 25

mta send with-subject both

mta send mail-from hostname LAB-UC540.lab.org

mta send mail-from username $s$

mta receive aliases 10.10.10.2

mta receive maximum-recipients 7


For the MMOIP, I have:


dial-peer voice 3020 pots

translation-profile incoming Lab_Fax_T37_Called_26

service onramp

incoming called-number 4627

direct-inward-dial

port 0/2/0:23


dial-peer voice 1801 mmoip

service fax_on_vfc_onramp_app out-bound

destination-pattern 4627

information-type fax

session target mailto:[email protected]


The above works remarkably well


This (generic CCA config) is broken:

dial-peer voice 3020 pots

translation-profile incoming Lab_Fax_T37_Called_26

service onramp

incoming called-number 4627

direct-inward-dial

port 0/2/0:23


dial-peer voice 1800 mmoip

description ** fax onramp for outbound faxmail to CUE **

service fax_on_vfc_onramp_app out-bound

destination-pattern ^....$

information-type fax

session target mailto:[email protected]


fax receive called-subscriber $d$

fax interface-type fax-mail

mta send server 10.10.10.1 port 25

mta send with-subject both

mta send mail-from hostname 10.10.10.2

mta send mail-from username $s$

mta receive aliases 10.10.10.2

mta receive maximum-recipients 7


Any suggestions?  Or do I build a small internal LAN smtp relay server?

So what would the resolution to this issue be then? i have the exact same "generic" configuration that has quit working. They get the notification in their vm saying they received a fax but they no longer get the email. No fax settings were changed at all for this. Would it be prudent to do a dial-peer #### pots and dial-peer voice #### mmoip for each fax recipient?

Hey there.  I wound up using their local barracuda box as the gateway for the SMTP relay to get the email back into their server.  Klunky but it works.

Hello,


The CUE is used with the script for t37 - there are two approaches with fax to email.

One is using the CUE and the other is not using CUE just to add the right information.
