Hope you can help. We have recently migrated a site in Brazil from a MD110 to CUCM 126.96.36.19900-1.
The end users would like to block Call collect callscoming in from the PSTN to all extensions except 4 special phones.
I have not used E1R2 before and the lines came up first time from Cisco example for Brazil so haven't had much dealings with in since.
Currenly a external person can place a call from their mobile with a prefix followed by our normal telephone number. The call is then placed to our phones and the CLI only show the user mobile number. When they answer they hear a message saying someone want to make a call collect call. Hang up or stay on the line to accept.
Below are the relevant parts of the 3825's config. Any help /config will be appriciated.
