Does anyone have a cisco ISR router working fully with 3cx.

I am able to make and receive calls with no issues at all where i am having an issue is outbound tones. Ie when you make a call to a IVR system and need to press 1 it does not work. I know my phones are good as they worked on the old Quintum unit i had.
 
i suspect it would be how the tones are passed through the pbx.
 
Do you have cisco smartnet on that router? You could open a support case with Cisco on it. If you dont have a contract I can help you look up documentation since I have a cisco login with access to pretty much everything. What I would like in return is a copy of the config on that router that you used to get it working with 3cx :) Are you using a PRI or FXO?
 
I worked out the missing bit. I am using an E1 interface although teh interface should be irrelivant.
dtmf-relay rtp-nte

The phones are SPA504G's and Grandstream 2020's.
