Hi,
I think the ringing duration is implementation dependent as previously stated. Have a look at "603 Decline" as a possible response - this is used in 3GPP SIP mappings for "no answer".
"21.6.2 603 Decline
The callee's machine was successfully contacted but the user explicitly does not wish to or cannot participate. The response MAY indicate a better time to call in the Retry-After header field. This status response is returned only if the client knows that no other end point will answer the request."

Hi Attila,
"480 Temporarily Unavailable" is not used for this purpose
RFC 3261 16.5 Determining Request Targets: If the target set remains empty after applying all of the above, the proxy MUST return an error response, which SHOULD be the 480 (Temporarily Unavailable) response.
So According to the RFC 3261, It will ring for ever
Following is the thread from sip-implementors
http://lists.cs.columbia.edu/pipermail/sip-implementors/2002-July/003390.html
But again it is in end point control, but in PSTN it is network control. This kind of functionality should be in network control.

Hi Thangarajan,
How long you want the destination UA to ring for depends on the implementation.
Normally UA's have some kind of configuration variable so that they can specify how long they should ring for. If the call is not answered with that time period, the destination UA will usually issue a "480 Temporarily Unavailable" response. (see RFC3261 for details on 480 response)

Hi,
INVITE UAC --------------------------->UAS 180 Ringing UAC <---------------------------UAS
We did not have any timer in proceeding state, so how long it has to ring in the UAS end ?
if we set some propriority time in UA, then end point will have the control over this time. But in PSTN network, network is taking care of this functionality, not endpoint.
Whether this functionality is take care by SIP Network ?
Regards, Thangarajan.
