1-to-1 nat in the Cisco world is not the same in the rest of the world. 1-to-1 nat just means that only the SipXecs server can use the specific public IP address to talk to the public internet. You still have to establish access rules that allow specific ports/services inbound to that public ip address, of which there are none defined currently.

I'll try them and report back. Will hopefully know something here in the next couple hours. FWIW, I have our Cisco firewall set to not block from this server outgoing on any tcp or udp port, and have port randomization turned off. This server also has a 1-to-1 NAT, so there should be no NAT issues going on. The fact that we have calls inbound without issue right now I believe has eliminated the firewall from the equation. --- On Wed, 12/8/10, Michael Scheidell <[email protected]> wrote: From: Michael Scheidell <[email protected]> Subject: Re: [sipx-users] Can't place outgoing calls - fast busy To: [email protected] Date: Wednesday, December 8, 2010, 3:13 PM On 12/8/10 4:10 PM, Victor Williams wrote: Followed this, same result...fast busy. Also get no additional activity in the sipxbridge.log file after your suggested changes. try a known itsp, like www.voip.ms. ($25 deposit.. 1.49C for first did, 1.1c/min plus .99c per month) if they work, its your ITSP. if it doesn't, then you firewall is messing things up (firewall is usually the culprit) -- Michael Scheidell, CTO o: 561-999-5000 d: 561-948-2259 ISN: 1259*1300 > | SECNAP Network Security Corporation Certified SNORT Integrator 2008-9 Hot Company Award Winner, World Executive Alliance Five-Star Partner Program 2009, VARBusiness Best in Email Security,2010: Network Products Guide King of Spam Filters, SC Magazine 2008 This email has been scanned and certified safe by SpammerTrap®.
