P-Asserted-Identity

Description

The P-Asserted-Identity header field can be used to convey the proven identity of the originator of a request within a trusted network. Since the From header field is populated by the originating UA it may not necessarly contain the actual identity. It usually is established by means of authentication between the originating UA and its outgoing proxy. The outgoing proxy then adds a P-Asserted-Identity header field to assert the identity of the originator to other proxies.

This header field has only meaning within what is called a trusted network by mutual aggreement on the requirements for its use by the parties involved.

The P-Asserted-Identity header field is defined in RFC 3325.

How P-Asserted-Identity (PAI) is handled in MOR

• If caller sends PAI, MOR reads it and resends to the calee automatically.
• If caller sends PAI and CallerID Number is 'Anonymous', MOR changes CallerID Number to the value from the PAI.
  • NOTE: CallerID Name is not changed! Only CallerID Number.
• If caller sends PAI and some Provider has P-Asserted-Identity usage enabled in it's Edit window, MOR ignores this setting, because it resends original PAI
• If caller is NOT sending PAI and some Provider has P-Asserted-Identity usage enabled in it's Edit window, MOR constructs PAI from CallerID, Server IP (from mor.conf file) and SIP Port (from sip.conf file).
  • NOTE: Provider CallerID rules are applied to every PAI sent to that Provider

In order to pass PAI from Caller to Callee automatically, set pass_pai = 1 mor.conf

Configuration for Provider to send PAI if it is not present from the Caller

Enable it per Provider basis in its Settings:

• Make sure correct external IP address is set in mor.conf in variable server_ip.
• SIP port will be taken from sip.conf, if not found, default one (5060) will be used.

Provider see my Calls with CallerID and name details as Anonymous (anonymous@anonymous.invalid)

In such case, check these details:

• If in Device of User which sends Calls Trustpid is enabled;
• If in Provider settings, to which Calls are being sent with PAI re-send, PAI is disabled;
• If pass_pai is enabled in mor.conf;
• If Trustpid is enabled on Provider side;
