DeleGate does not support SIP (yet).
Thre are several ways to convey UDP over TCP using a pair of DeleGate.
The simplest one is using a pair of DeleGates for UDPrelay.

  hostA$ delegated -P2000 SERVER=udprelay://hostB:3000.tcp
  hostB$ delegated -P3000.tcp SERVER=udprelay://hostC:4000

With this configuration, UDP port at hostA:2000 will be forwarded
to hostC:4000, via TCP port at hostB:3000, as follows:

  --(UDP)-- hostA:2000 --(TCP)-- hostB:3000 --(UDP)-- hostC:4000
