Internal friends

Internal friends allows a vPBX client to call to Extensions of another vPBX client in the same Corporation.

Important

Only extensions in Extensions section.

If calling to an extension in another vPBX causes an external call, it is allowed:

  • Calling to a user with an external call forwarding settings.
  • Calling to an extension routed to an external number.
  • Calling to an extension routed to a IVR with an option pointing an external number.
  • Etc.

What kind of calls can be routed through an internal friend?

IvozProvider will route any call matching an Extension in vpbx client connected by the internal friend.

Configuration of internal friends

These are the configurable settings of internal friends:

Description
Optional. Extra information for this friend.
Priority
Used to solve conflicts while routing calls through friends. If a call destination matches more than one friend regular expression the call will be routed through the friend with less priority value.
Connectivity mode
Choose “IntervPBX” for internal friends.
Target Client
vPBX client inside the same corporation you want to connect.
Fallback Outgoing DDI
If called extension causes an external call, this DDI will be used as source number.
Always apply transformations
Numbers listed in Extensions section of both source and destination client will be considered as internal and won’t traverse numeric transformation rules. Enable this setting to force Numeric Transformation rules even on these numbers.

Note

Calls to friends are considered internal. That means that ACLs won’t be checked when calling a friend, no matter if the origin of the call is a user or another friend.

Summary of internal friends

These are key points to understand internal friends:

  • They have been designed to allow users from a vPBX to call to extensions (normally users) of another vPBX of the same corporation.
  • Usually they will allow user-user calls.
  • You cannot use an internal friend to generate external calls paid by the other client.
  • But external calls may happen if extensions are pointed to external numbers (controlled external calls).
