Subject: [Sip-implementors] wait time for 200 ok

Hi all,

Suppose A calls B.

B responds with 180 Ringing. But does not send 200 ok or 200 ok gets
lost.

How long should A wait before sending Cancel / Request timeout?

[ABN] the INVITE client transaction exists for duration Timer B (64 *
T1). Once Timer B fires all the early dialogs are considered terminated.
AFAIK no CANCEL would be send for early dialogs exists at this point in
time.... (I mean when Tb expired no CANCEL would be sent to cancel any
of the existing early dialogs...)
