One-Password Call Flow
ReadiVoice-IP has three possible IP tributaries for one-password call flows.
Clear Text Password
In this type of SIP
INVITE
, the
TO
header includes the access code and
password. It has the following format:
TO: sip:accessnumber@host;AC=accesscode;PCODE=password
When the header has this format, the caller enters the traditional ReadiVoice
call flow after the password prompt (rather than being prompted for an access
code and password). If the password within the header is invalid, the system
sends a
401 Unauthorized
response to the
INVITE
.
PCODE=""
is valid if the participant password field in the database is empty.
Per Call Authorization
In this type of SIP
INVITE
, the
TO
header includes the access code and
verification of authorization. It has the following format:
TO: sip:accessnumber@host;AC=accesscode;AUTH=TRUE
When the header has this format and the SIP protocol authorization is valid,
the caller enters the traditional ReadiVoice call flow after the password
prompt (rather than being prompted for an access code and password). If the
authorization within the header is invalid, the system sends a
401
Unauthorized
response to the
INVITE
.
Trusted Proxy
In this type of SIP
INVITE
, the
TO
header includes the access code and
participant type. It has one of the following formats:
TO: sip:accessnumber@host;AC=acccesscode;PTYPE=SUBSCRIBER
or
TO: sip:accessnumber@host;AC=acccesscode;PTYPE=PARTICIPANT
When the header has one of these formats and the
INVITE
comes from a
trusted proxy, the caller enters the traditional ReadiVoice call flow after the
password prompt (rather than being prompted for an access code and
password). If the proxy is not a trusted proxy, the system sends a
401
Unauthorized
response to the
INVITE
. If the
PTYPE
specified is not valid, the
system sends a
400 Bad Request
response to the
INVITE
.
