I can log in with the iPhone Jabber client but it only connects to IM/P and cannot register to CUCM / "Phone Services". Should this work by default in the Collaboration sandbox or is additional configuration required?
what topology have you reserved and what is your sandbox username?
I reserved a Collaboration 10.5 sandbox / username aaron-counterpath.
I re-tested again today but observed the same behaviour. Should the iOS Jabber client be able to log in using the out-of-the-box sandbox config and the pre-provisioned users? e.g. email@example.com should be able to log in and call/IM to firstname.lastname@example.org
