It sounds like a layer three problem. Are all of the Subnet masks and gateways configured correctly? Obviously, you can ping, but you are unable to connect without the ping. It sounds like both the SIP phones and the IAX customers are unable to find a route back to your asterisk server, but when you ping the devices, they 'see' the route and take it.
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robert Jackson Sent: Saturday, April 10, 2004 9:25 AM To: [EMAIL PROTECTED] Subject: [Asterisk-Users] Newbie Issues => SIP won't stay connected, and IAX Unable to Create Channel I am terribly sorry to bother the list with such generic and bizarre problems, but I have been racking my brain with these for the last week working on it for at least 60 hours. If anyone can even point me in the right direction I would be eternally grateful. So without further adu here are my woes: I have * (2004-04-09 CVS) running on a P4 1.6Ghz CPU, 512MB RAM, Debian "Sarge", and basically no other programs (Other than the required ones of course). My SIP clients are 2 Win2000 machines running X-Lite, and 2 grand stream budgettone 101's. All iptables default rules are set allow and no other rules are entered. The whole setup is a proof of concept so that we can migrate our 25 agent call center app to *. When I reboot the computer running * and run * via asterisk -vvvvgc everything starts without any warnings, notices, or errors. At that point none of my SIP clients login to *. If I do a sip debug it doesn't even show the clients trying to connect, however on the X-Lite logs it is sending the REGISTER message to the correct IP address. If I ping the client's IP address from the * server the client immediately registers and can make calls. If I stop pinging for at least 30 minutes the clients are again unable to connect. Upon discovering this I thought that I had a physical network problem. So I went out and got a brand new 10/100 switch, and new network cards for the server and the PC based clients. After installing and configuring all the new equipment I am in the same boat. I simply cannot understand what is going on. All of the machines are on a local address scheme without any NAT's or other firewalls in between. The next problem that I have has to do with IAX. I have accounts setup with both NuFone, and VoicePulse just to try out the various services. I have my iax.conf configure as instructed by both the wiki and from the providers. I also have a DID from VoicePulse so I have a register line for that as well. After I reboot the * server, run *, and ping the clients both provider's work properly. However after a certain period of time(variable length) the register times out and VoicePulse becomes "UNREACHABLE". The same goes for the NuFone service. When this happens occasionally I get a message on the console that says "Unable to create channel". I am completely at a loss. Again I apologize for wasting your valuable time, but I couldn't find anything that helped me either on the wiki or the list.
