Hi folks,

    I am trying to find out the methods supported by SER. I am aware that SER is RFC-3261 compliant, but, do not know to what extent. If someone can tell me what (in 3261) is supported and what is not, that would be nice. Also, if SER supports any extensions (3262, 63, 64), please let me know.

 

After some Googling, I found that the basic methods of SIP are:

INVITE – to initiate a session

Re-INVITE – if, during a call, either party wants to change the media; for example to open a video channel

ACK – to confirm session establishment and can only be used with INVITE

BYE – terminates sessions

CANCEL – to cancel a pending INVITE

OPTIONS – for capability inquiry

REGISTER – to bind a permanent address to current location

 

The other methods (found in extensions) of SIP are:

Other SIP method extensions are defined in different RFCs such as:

SUBSCRIBE – to subscribe to a service state change. sed for presence (subscribe to an event and receive

notification), call-back (when other party becomes vailable), voice mail notification, any event that can be

associated with a trigger (e.g., stock quotes, etc.)

NOTIFY – notify a change of service state (e.g., new voice message).Works in parallel with SUBSCRIBE

MESSAGE – for Instant Messaging (user to user messaging). MESSAGE requests carry the content in the

form of MIME body parts

REFER – call transfer

 

Does SER support all the above Basic methods? Can someone tell me if SER supports any of the extensions? Basically, I am trying to use SER for VoIP integration and I am trying to get all the data I can about SER for interoperating with various SIP phones. I will not be using Asterisk for now (as a part of VoIP integration).

 

Thanks much,

Sri.
