By looking the error "Unable to find a device handler" what i believe is your CUCM IP address which is in the CVP Static Route is not listed in the CallManagerGroup which is assigned to your SIP Trunk's Device Pool.
What is the CUCM Version you use. If you are using 8.5 and above you can use the below feature
SIP Trunks Can Run on All Active Unified CM Nodes
When the Run on all Active Unified CM Nodes option is checked on a SIP trunk, Unified CM creates
an instance of the SIP trunk daemon on every call processing subscriber within the cluster, thus allowing
SIP trunk calls to be made or received on any call processing subscriber. (Prior to this feature, up to three
nodes could be selected per trunk by using Unified CM Groups.) With Run on all Active Unified CM
Nodes enabled, outbound SIP trunk calls originate from the same node on which the inbound call (for
example, from a phone or trunk) is received. As with all Unified CM SIP trunks, the SIP daemons
associated with the trunk will accept inbound calls only from end systems with IP addresses that are
defined in the trunk's destination address fields. Running SIP trunks on all nodes is recommended where
the SIP trunk is required to process a large number of calls so that outbound and inbound call distribution
can be evenly spread across all call processing subscribers within a cluster. Also, when multiple SIP
trunks to the same destination(s) are using the same subscriber, a unique incoming and destination port
number must be defined per trunk to allow each trunk to be identified uniquely.
