Grandstream Phones do have a bug where they sometimes send an UDP packet to port 0 instead of port 5060. The effect is that you see 5 times the error message
WARNING4101: chan_sip.c:601 retrans_pkt: Maximum retries exceeded on call [EMAIL PROTECTED] for seqno 22209 (Critical Response) on the asterisk box, because Asterisk sends some Command to the BudgetTone, and the Budgettone answers, but to port 0. So Asterisk retries ... up to 5 times. See http://www.voip-info.org/wiki-Asterisk+phone+grandstream+budgetone under "Early Dial" (althought the bug appears with other SIP traffic as well). For a crude fix, you can use the IP port redirection of Linux: iptables -t nat -A PREROUTING -p udp -i eth0 --dport 0 -j REDIRECT --to-port 5060 -- http://www.holgerschurig.de _______________________________________________ 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
