Thus even if another NE do not support it and your UA does, you will be able to detect any broken connection. cheers!! sarvpriya On Wed, Oct 6, 2010 at 11:40 AM, Alex Balashov <[email protected]>wrote: > On 10/06/2010 01:52 AM, Manoj Priyankara [TG] wrote: > > > If there's a LAN cable disconnect during a SIP session that is during a > > call how does the other party recognize it?
