Given I have a trunk and a user configured
Given I set the outgoing caller ID of my user to Anonymous
When I make a call
Then the operator doesn’t use the anonymous and fallback on a DID configured

Expected: Anonymous caller ID is used

Technical:

Our Anonymous system doesn’t follow the recommandation by RFC to work by default on most VOIP providers.

When using anonymous, we should send the following headers:

Note:

• Latest asterisk version should have new method to update headers

• We don’t want to add send_pai: yes in the registration_trunk template, because we don’t necessarily trust the environment

• We may want to make difference between trunk using authentication by IP and those using authentication by user/password

• A more extended investigation about different VOIP provider should be done

• Asterisk already implement all this behavior with different options:

  • trust_id_outboundwill send Private: id with P-Asserted-Identity header

  • callerid_privacy: prohib will change From to "Anonymous” <sip:anonymous@anonymous.invalid>

Acceptance Test:

Make it work with VOIP operator support anonymous call.
