XML Services were introduced on the 7920 after the initial releases of CallManager versions 4.0 and 4.1. It requires a firmware upgrade on your 7920 phones, and a patch to CallManager to enable Services subcription on the 7920 device type. You were likely using an ES or service release of 4.0(2a) such as 4.0(2a)SR2c, or possibly one of the downloadable DevPacks, that brought in 7920 XML Services support. You don't mention the exact version in the CallManager 4.1 train you upgraded to, but assuming you upgraded to CallManager 4.1(3), you need SR1 or newer to enable 7920 XML Services support. The 7920 firmware upgrade comes along with the service release and is performed by CallManager automatically, so you don't typically need to worry about that.
The latest available is 4.1(3)SR2, and it's highly recommended that you get that and apply it since it includes a great number of other bugfixes and minor enhancements. You should always apply the latest available service release when upgrading. If you only upgraded to 4.1(2) for some reason, you should really upgrade to 4.1(3) and then apply SR2.
