Line/Device CSS for FXS ports

I am using line/device approach for my CSS for the phone, but seems like the FXS port Line/Device does not work. Is that correct? I used DNA to verify that. I assigned a PSTN-CSS to my analogue device and then a block CSS on the DN but it always used the device CSS for calling? Can someone help with this? Thanks

Re: Line/Device CSS for FXS ports

it should be no different. Are your FXS ports MGCP controlled or are you using h323 to route the calls back to the FXS ports?

Re: Line/Device CSS for FXS ports

I am using MGCP gateway. I have tested on both CCM 4.1 and 6.0 version using DNA and both show that it can only use the device CSS to route calls.

anyone who check this using their DNA. Am I missing something or is this a known bug?
