  Fixed entity index in the b2b callbacks.

After some rework of the B2B API, the entities are counted starting from 0, while before they were form 1 - this was affecting the call center logic by mixing the caller versus callee parties of the call.

Reported by Jonathan Hunter - many thanks also for testing !!
