Interop Parameters Reference Manual (SIP Version)
Mediatrix 4104 279
SIP From: URI Content
You can specify the composition of the domain used in the from : URI of SIP requests sent by the unit.

To specify the composition of the domain used in the from : URI:
1. In the sipInteropMIB , set the sipInteropFromUriDomainSelection variable with the proper behaviour.
Network Asserted Caller ID
The Mediatrix 4104 can extract the caller ID information from the P-Asserted-Identity header (a SIP extension
described in RFC 3325) instead of the From header of the incoming SIP request

To use the P-Asserted-Identity header:
1. In the sipInteropMIB , set the sipInteropUsePAssertedHeader variable with the proper behaviour.
Payload Type Settings
The following are settings related to the DTMF payload type.
Using the Payload Type Found in the Answer
The default behaviour when sending an initial offer that contains an RFC 2833 payload type is to keep using
that payload type even if the response comes back with a different one. You can set the Mediatrix 4104 to
rather use the payload type found in the answer.
enable The request URI is built using the SIP domain, if one is specified, for all SIP methods
with the exception of REGISTER and PUBLISH. The parameter maddr is also
added to the Request URI with the value of the home domain proxy host. See
“User
Agents” on page 257 for information on how to set the SIP domain.
Table 182: SIP Domain in Request URI Behaviour (Continued)
Parameter Description
Table 183: SIP From: URI Content
Parameter Description
sipDomain The domain of from:URI is built from the sipDomain variable ( “User
Agents” on page 257 ). If sipDomain is empty, the
sipHomeDomainProxyHost value is used instead ( “Proxy Server” on
page 165 ). This is the default value.
localHostWanAddress The domain of from:URI is built from the unit address taken from the
localHostWanAddress variable ( “WAN Address Configuration Source”
on page 144 ).
localHostFqdn The domain of from:URI is built from the unit's FQDN taken from the
localHostFqdn variable. If localHostFqdn is empty, the value of the
localHostWanAddress variable is used instead.
Table 184: Network Asserted Caller ID Behaviour
Parameter Description
disable Caller ID data is based on the value assigned to the From header of the incoming
SIP request. This is the default value.
enable The unit first attempts to get the caller ID information from the P-Asserted-Identity
header, if present. In case of failure, it falls back to the content of the From header.
