Symptom:
Jabber is unable to resolve the name for incoming calls with calling party number which are E.164 numbers ( with a plus sign). This is for the scenario where customer uses UDS as the contact source for directory look ups.

when Jabber gets an incoming call, it will send a UDS query to call manager like below:

https://10.106.83.196:8443/cucm-uds/users?max=4&start=0&number=+9111223344

However, call manager is unable to process the same as it cannot process a special character like '+'. 


Jabber is able to resolve any other numbers correctly. The issue is always reproducible with latest version of Jabber and CUCM versions 9.x / 10.x.
