| Counters |
| SIP Counters Information |
Method | Displays the SIP counter information. The available options
are: - BYE— Number of BYE requests sent. A user
sends a BYE request to abandon a session. A BYE request from either
user automatically terminates the session.
- REGISTER— Number of REGISTER requests
sent. A user sends a REGISTER request to a SIP registrar server to
inform it of the current location of the user. The SIP registrar server
records all the information it receives in REGISTER requests and makes
this information available to any SIP server attempting to locate
a user.
- OPTIONS— Number of OPTIONS requests sent.
An OPTION message is used by the User Agent (UA) to obtain information
about the capabilities of the SIP proxy. A server responds with information
about what methods, session description protocols, and message encoding
it supports.
- INFO— Number of INFO requests sent. An
INFO message is used to communicate mid-session signaling information
along the signaling path for the call.
- MESSAGE— Number of MESSAGE requests sent.
SIP messages consist of requests from a client to the server and responses
to the requests from the server to a client for the purpose of establishing
a session (or a call).
- NOTIFY— Number of NOTIFY requests sent.
A NOTIFY message is sent to inform subscribers about the change in
state of the subscription.
- PRACK— Number of PRACK requests sent.
The PRACK request plays the same role as the ACK request, but for
provisional responses.
- PUBLISH— Number of PUBLISH requests sent.
The PUBLISH request is used for publishing the event state. PUBLISH
is similar to REGISTER that allows a user to create, modify, and remove
state in another entity which manages this state on behalf of the
user.
- REFER— Number of REFER requests sent.
A REFER request is used to refer the recipient (identified by the
Request-URI) to a third party identified by the contact information
provided in the request.
- SUBSCRIBE— Number of SUBSCRIBE requests
sent. A SUBSCRIBE request is used to request current state and state
information updates from a remote node.
- UPDATE— Number of UPDATE requests sent.
An UPDATE request is used to create a temporary opening in the firewall
(pinhole) for new or updated Session Description Protocol (SDP) information.
The following header fields are modified: Via, From, To, Call-ID,
Contact, Route, and Record-Route.
- BENOTIFY— Number of BENOTIFY requests
sent. A BENOTIFY request is used to reduce the unnecessary SIP signaling
traffic on application servers. Applications that do not need a response
for a NOTIFY request can enhance performance by enabling BENOTIFY.
- SERVICE— Number of SERVICE requests sent.
The SERVICE method is used by a SIP client to request a service from
a SIP server. It is a standard SIP message and will be forwarded until
it reaches the server or end user that is performing the service.
- OTHER— Number of OTHER requests sent.
