We had this same issue running CUCM and Presence 10.5 on desktop Jabber clients, with the only difference being that if a user was logged into the internal LAN, both inbound and outbound calls worked from Jabber, but over a VPN connection, only outbound calls worked. Inbound calls would still ring the user's desk phone in the office, but would not ring the Jabber phone.
After a lot of troubleshooting, both in CUCM and on our ASA's, we discovered that the one variable that fixed the issue was turning off SIP packet inspection on the perimeter firewall. With packet inspection turned on, Jabber would not receive calls over VPN, but as soon as we turned it off, inbound calls worked fine.
Since iPhone and iPad Jabber clients generally behave similarly, needing to go through the firewall, maybe this will provide a place to start looking.
