It's the RTP Stream Asterisk by default uses ports UDP 10,000 to 20,000
RTP = Audio Open them on your firewall. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andrew Aken Sent: 07 December 2004 15:21 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] Firewall traversal anomalies - AJA I'm trying to setup a Cisco ATA 186 which has a public IP address but sits behind a firewall and connects to an Asterisk server with a NAT IP address sitting behind a BSD firewall. The Cisco registers with the Asterisk server without any problems, and I can place calls without any problems and the phone on the other end rings correctly. However, I cannot hear anything through the Cisco after the connection is made. Where should I begin looking for the problem? This is the sip.conf entry for the Cisco: [6184341501] callerid="GlobalEyes" <6184341501> canreinvite=no context=from-internal dtmfmode=rfc2833 host=dynamic mailbox=xxxxx nat=yes port=5060 secret=xxx type=friend username=xxxxx allow=all _______________________________________________ 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
