newbie needs help with setting up an analog port on CME for fax service

very new to Cisco and router configuring but was given the attached config for a CME running on a Cisco2821 router. I am taking over for another person who left the company and would normally do this testing from a customer cpe perspective. I am needing to add config for an analog port that will be used for fax testing of T38 with our broadsoft hosted platform. this uses a SIP trunk to broadsoft for the PSTN connection.

Is there some documentation or some examples on how to configure this? It only needs to be a basic analog port that can do faxing. We will be testing with passthrough and also T.38

thanks in advance

Hello Brian,

Kindly check this document .

http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-border-element/115742-fax-modem-call-flows-00.html

Hope this would help.

thanks for the quick reply. Looking over that real quick the document doesnt seem to cover what i have setup. maybe you can recommend which setup is more closely resembled to what i have currently. My setup is as follows:

Fax ---> FXS ---> CME/2821Router ---> SBC ---> SIP Trunk to Telco

The SBC is not Cisco.
