The BT100's do support conferencing, most SIP phones do. But how does your Asterisk connect you to the PSTN? Through a Zap interface? If so, what kind; or through a VoIP provider like BroadVoice, NuFone, LookieLoo, VoipJet, VoicePulse?
You basically need to make sure your Asterisk server has access to more than 1 line. If it does, then you should be able to 3-way call without any problems. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Friday, January 21, 2005 1:20 PM To: [email protected] Subject: [Asterisk-Users] three way call using sip Hi, i cant make a three way call using grandstream phones (BT-100) and asterisk using sip, is this supported or i need a zap interface? thanks _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
