Description
This setting determines which header to use as the source for the Refer-To header in a REFER.
When this setting is set to:
- on, the Contact header is used,
- off, the remote AoR (taken from To or From header, depending on the direction of the call) is used
- empty, the phone will adjust automatically the value following the next registration. If the phone is configured for Broadsoft (refer to user_server_type setting) or has no GRUU configured, the enforced value will be off (AoR header), otherwise on (Contact header).
