Hello All, My test server has a dedicated public IP and was set up using the article from ONLamp: http://www.onlamp.com/pub/a/onlamp/2003/07/03/asterisk.html except that I fixed the mailbox entries in the sip.conf. Can some one please tell me what this means? --------------------------------- Asterisk Ready. *CLI> Feb 27 09:05:32 WARNING[20752]: chan_sip.c:1116 retrans_pkt: Maximum retries exceeded on call 6062DE59-1E68-4EEA-95F5-F8D5A9683020@192.168.0.101 for seqno 34581 (Non-critical Response) Feb 27 09:05:41 WARNING[20752]: chan_sip.c:1116 retrans_pkt: Maximum retries exceeded on call 6062DE59-1E68-4EEA-95F5-F8D5A9683020@192.168.0.101 for seqno 34581 (Non-critical Response) Feb 27 09:06:25 WARNING[20752]: chan_sip.c:1116 retrans_pkt: Maximum retries exceeded on call 42AAF14E-E612-43E5-9E44-777C5270AF19@192.168.0.101 for seqno 19228 (Non-critical Response) Feb 27 09:06:36 WARNING[20752]: chan_sip.c:1116 retrans_pkt: Maximum retries exceeded on call 42AAF14E-E612-43E5-9E44-777C5270AF19@192.168.0.101 for seqno 19228 (Non-critical Response) -------------------------- I set up a fresh Asterisk test server on a host and tried to connect to it twice using the X-Lite softphone but get the same messages.
