ISN dialing to Screaming Monkeys (1234*256) for 6+ min. seemed work fine for me as well. Admittedly, I haven’t used ISN enough to identify any problems or patterns.
I use a Cisco 1841 for my firewall. You can roam around my AA menus if you’d like in order to test against another firewall. 4030909*1258 From: Michael Scheidell [mailto:[email protected]] Sent: Monday, July 19, 2010 6:35 PM To: Tony Graziano Cc: [email protected] Subject: Re: [sipx-users] sip dialing, no audio after 5min On 7/19/10 6:28 PM, Tony Graziano wrote: Er, uh... I think I called you with my pfsense last week via ISN, I am using pfsense 2.0, so that went on for more than 5 minutes. inbound seems fine. I'll play in the office some. was hoping to send keepaliaves on tcp port 5060 to the far end, tshark port 5080 or 5060 didn't show ANYTHING while call was active. I think you need to find someone with a firewall OTHER THAN those listed and see if they will let you call for more than 5 minutes. Last I heard Nathaniel is also running pfsense (but I think not 2.0). I have other sites I can log into with a softphone but they all front pfsense, so I am afraid I might be of no use to you in this instance. I think it might be something to do with how the remote firewall ACK's the call and drops it after 5 minutes because it cannot tell it is established. It might not be anything to do with keepalive, but an ignorant signalling interpretation, but don't take my word for it. I suspect that is what it is. I also can't (reliability) forward calls from them. -- Michael Scheidell, CTO Phone: 561-999-5000, x 1259 > | 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®.
