RE: [reSIProcate] Process for case where no response after receiving1xx in client INVITE transaction

["Derek MacDonald" <derek@xxxxxxxx>]

Currently, the use has to CANCEL the call.  There should be a timer for
this, but it isn't clear what the value should be(probably configurable in
profile).

Anybody have a good idea for the default value of this timer?
