That's basically the correct technique. If the static routes are in CVP, there is a SIP trunk from CUCM to CVP; if the static routes are in the SIP Proxy, there is a SIP trunk from CUCM to the Proxy. If there is more than 1 of either of these devices, you need more than 1 trunk.
If the agent is going reserved, that implies that the correct label is being given to CVP through the PG. Say it's 71234. So CVP has to resolve it and you have a static route for 7> to the two subscribers. You do need to set the number of retries on INVITE to 1 (so it doesn't keep INVITING the down CUCM) and flips to the other one.
The normal way to solve this is to use the CVP diagnostic servlet and turn on DEBUG on the SIP service and on the Dynasoft library - this will give you the complete SIP messages. Follow these through and see what's being returned on the INVITE. If it's a 503 (resource unavailable) then you have a misconfiguration in CUCM with respect to the resources the trunk is in and the resources the phone is in.
So examine the SIP messages in their gory detail and see what they say.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
