Trunk to trunk forward

How do I simply forward call coming via SIP/TrunkA to SIP/TrunkB with same DID and preferably same CID?
TrunkA and TrunkB are SIP Peers (without SIP registration).

If anyone will read this post - the solution is to:

  1. send the call from TrunkA to a created custom extension
  2. then forward that custom extension to TrunkB and set “dial” field to SIP/[email protected] (where “number” is original DID)

In order to preserve the DID and CID you need to manually create custom context.
