Janet,

Hello. Yes, I have done some preliminary testing with Sipdroid on CUCM. So far I have been able to get it to register, place/receive calls, etc. I have not tested the application much beyond that. I recently did a write up on how to configure Sipdroid to communicate with CUCM.  Maybe you will find this helpful.

HTH.
