I don't think there are hard limits. I mean you've got hard and fast limits of dsp's, and you've defined max-connection limits on those dial-peers, but as far as the number of call legs that a device can terminate... There are a lot of factors at play. It depends on what else you're doing on that device. Cisco might have published some best practice type numbers around the UCxxx boxes but I haven't seen them (I haven't searched exhaustively though). You haven't mentioned which IPBX you're using, but you've got some hard upper caps based on the software/hardware you're using for those as well.
Those 2 dial-peers do limit you to10 calls from A - B and 10 calls from B - A however but wouldn't cause an in-progress call to drop but could cause a transfer/conference attempt to fail. I'm assuming that you don't have CAC in place. You could use RTMT and UCM traces, but since you've got a UBE I'd just run a sip message debug. The output is very readable and you should be able to see what's happening pretty easily.

No. You will only need the SRST licenses on the primary router. Because this feature...
