Connect the AI phone agent with call forwarding
Not every telephony service allows a SIP trunk to a third party. In that case the agent gets its own phone number at Tibinet, and your telephony forwards calls to it. That way the AI agent works even if your provider does not offer a trunk.

When to use call forwarding
Some cloud platforms, Aircall for example, do not allow a SIP trunk of your own. Many Dutch hosted telephony providers also do not let customers set up a trunk to a third party. In those cases, forwarding to a number of the agent is the way to go. Belcentrale was acquired by Techone in 2020 and has continued as Digihero since December 2020; this works there too, as long as you can forward to an external number.
How it works
The agent gets a number
A new phone number at Tibinet, or an existing number transferred through number porting.
You set up forwarding
From a menu option, a queue, outside opening hours, when busy or when unanswered, your telephony forwards the call to the agent's number.
The agent transfers when needed
If a person needs to step in, the agent transfers the call to a phone number you choose, such as your reception's direct line.
Worth knowing
- Call minutes. Most providers charge call minutes for forwarding, because it is an outbound call from your phone system.
- Caller's number. Whether the caller's number is passed on depends on your provider. If it is not, the agent sees the number of your phone system.
- Cold transfer. With forwarding to a number, the agent transfers calls cold, to a phone number.
