On FXS interfaces, this represents the value of the pstn.in.ani parameter (Caller number) in a PSTN IN → SIP OUT call. A channel group will be created for each FXS interface with for ID their phone number. When in a SIP IN → PSTN OUT call, by default, if the called number matches one of the FXS interfaces phone numbers, the default_analog_fxs_pstn_out routing rule will be used.
On FXO interfaces, this represents the value of the pstn.in.dnis parameter (Called number) in a PSTN IN → SIP OUT call. The dnis value will then be added as the user part in the SIP INVITE message. For example, a call coming on FXO interface with phone number 1234 would result in the following INVITE message headers:
INVITE sip:1234@server_host:5060;transport=udp;user=phone SIP/2.0
From: "unknown-caller-name" <sip:unknown-ani@gw_host:5066>;tag=pxip-callid-1300817435-935380-41-225ds-2cd6-71b68f36
To: "1234" <sip:1234@server_host:5060>
