CUBE setup with ITSP

[rramlal]

Hi Team,

I wanted to find two things about the SIP trunks that I have setup. Firstly I have 2 CUBEs setup with two sip trunks back to CUCM. These CUBEs connect to the ITSP. Now my route plan has both sip trunks set with a top down cycle. Each trunk has 15 channels. How will top down work for this? How will call manager know to send the calls to the second gateway if the 15 channels on the SIP provider is used up?

I know with the T1 it is able to see the channels and switchover. I was actually thinking of round-robin setup. 

Additionally is there a command that shows the sessions active with the ITSP calls? Similar to how the analog lines are?

My ASSUMPTION with your other question is that if you're using the following command - mode border-element license capacity 15 - on your CUBE it would reject the call and CUCM would then route to your other CUBE. Not really sure though.
