[Asterisk-Users] double-dial in SIP Grandstream

[Paul Liew]

"callwaiting=no" is not supported by chan_sip. Call waiting
enabling/disabling is a function of SIP phones. Unfortunately, GS does not
support disabling call waiting as yet, so I've had to put in a patch to
overcome the problem. Look under
http://bugs.digium.com/bug_view_page.php?bug_id=0000408. You need
"incominglimit=1" to stop the ringing caused by callwaiting when you are on
the phone.
