Claims26
A method in a user agent (UA) for identifying an originator of a Session Initiation Protocol (SIP) reject response, the method comprising:
- sending a SIP request;
- and
- receiving, from the originator, a SIP reject response to the SIP request, the SIP reject response including an indicator comprising a parameter “fe”, the indicator indicating an assignment of one of a plurality of types of network nodes to the parameter “fe”, the indicator indicating a type of network node for the originator.
A method in a user agent (UA) for identifying an originator of a Session Initiation Protocol (SIP) reject response, the method comprising:
- receiving a SIP request;
- and
- sending a SIP reject response to the SIP request, the SIP reject response including an indicator comprising a parameter “fe”, the indicator indicating an assignment of one of a plurality of types of network nodes to the parameter “fe”, the indicator indicating a type of network node for the originator.
A user agent (UA) to identify an originator of a Session Initiation Protocol (SIP) reject response, the UA comprising:
- one or more processors configured to:
- receive a SIP request;
- and
- send a SIP reject response to the SIP request, the SIP reject response including an indicator comprising a parameter “fe”, the indicator indicating an assignment of one of a plurality of types of network nodes to the parameter “fe”, the indicator indicating a type of network node for the originator.
A user agent (UA) to identify an originator of a Session Initiation Protocol (SIP) reject response, the UA comprising:
- one or more processors configured to:
- send a SIP request;
- and
- receive, from the originator, a SIP response to the SIP request, the SIP response including an indicator comprising a parameter “fe”, the indicator indicating an assignment of one of a plurality of types of network nodes to the parameter “fe”, the indicator indicating a type of network node for the originator.
A non-transitory computer readable medium comprising instructions that when executed by a processor of a user agent (UA) configured to identify an originator of a Session Initiation Protocol (SIP) reject response, cause the processor to:
- receive a SIP request;
- and
- send a SIP reject response to the SIP request, the SIP reject response including an indicator comprising a parameter “fe”, the indicator indicating an assignment of one of a plurality of types of network nodes to the parameter “fe”, the indicator indicating a type of network node for the originator.
