We got SIP Trunk between CME and Nortel CS1000. Is there any steps to check if SIP Trunks are up with no errors.
Make a call, see if it works..
Try any other scenarios you can think up - generally testing features like hold, transfers on either side to see if it breaks.

Is it possible to check from CME console for SIP Trunks activity ( Up/Down/Errors )
How to check which dial-peer is used for calls originating from PSTN to endpoints terminating on Cisco.
PSTN is terminated on Nortel ; SIP trunk is between Nortel & Cisco
The answer you have been given already is correct. SIP trunks do not have UP/down state and error counters associated, they are stateless.
You should be able to tell wich DP is used by looking at the configuration. To verify, you can enable debugs.
Thanks p.bevilacqua for your input
Is is possible to check the number of channels used on the sip trunk.
SIP trunk do not use channels.
Since seems like you have many doubts, recommend you engage a true engineer to help you with these things.
