P-Asserted-Identity (outgoing calls from a chosen number for experienced users)
During outgoing calls via SIP (with authorisation through registration or by IP) you can use SIP heading P-Asserted-Identity to choose CallerID from the list of numbers connected in the service.
Number from the P-Asserted-Identity heading will be prioritised . If the heading is not set or has an incorrect/not connected number, the default number will be used.
When authorised by IP (SIP-trunk), the number can be set in the From heading.
