RE: [Asterisk-Users] Cisco 7960

[Matthew Hardeman]

Here’s a hint… Upgrade back to 5.1.  It still has bugs, but they’re no worse than 5.0…   Put it in the same subnet as the asterisk server, and make sure that the eth0 interface (the FIRST interface in the box) is on that subnet.  Generally, you will want this to be your internal address space.  192.168.0.x…  If you asterisk server needs an external IP on the same Ethernet, just do an alias as eth0:1 or something along those lines.  Make the primary hostname of the server (as reflected by the hostname command) match up in /etc/hosts as the internal IP address.   Asterisk apparently picks up the first IP address on the system to use as its source IP address for all things SIP…  If you have a Cisco phone communicate with Asterisk on another subnet known to the system (via an IP alias on the same Ethernet card), I’ve found that the Cisco 7960 will crash and burn.  I suspect that if Asterisk were modified to source the communications back over the interface it received them, the crash would no longer happen.   Check your configuration files… I’ve had these phones crash on me before if your networking isn’t very friendly to them, but never before just during the booting sequence…  Trust me; you can get this phone to work… It’s just a matter of patience and experimenting, and lots of free time wasted on Ethereal… J   As an aside, I’ve actually been actively working with a Cisco developer (even today) to generate more debug information for them on the network caused crash and reboot issue, and they think they’ve about got it licked…  I believe they will be sending me a firmware image to test soon that will have at least that bug, and probably more, fixed.   Matt Hardeman PaperSoft   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of William Carlson Sent: Thursday, July 17, 2003 5:10 PM To: [EMAIL PROTECTED] Subject: Re: [Asterisk-Users] Cisco 7960   Cisco's website has some stuff on there website which seems to indicate if the 7960 cannot contact the call manager server it reboots. However to my knowledge this has never had call manager software before and cisco doesn't mention this "feature" with the SIP firmware. I downgraded to 5.0 unfortunately due to only being able to run Secure images now thats as far back as I can go. Thanks again cisco for this "feature".   From what I can tell the phone never talked to the Asterisk box. If I turn on SIP debugging I do not see any traffic coming from the cisco box. Although I did have them on seperate subnets. Let me try putting them on the same subnet and see if that helps.   Thanks,      Will ----- Original Message ----- From: Matthew Hardeman To: [EMAIL PROTECTED] Sent: Thursday, July 17, 2003 12:58 PM Subject: RE: [Asterisk-Users] Cisco 7960   I’ve run into this before, and it’s a pain to debug…   Be sure that your eth0 interface (primary, first interface) is set to your internal address space (of the same subnet that you assign to the phone).  You can add an IP alias on eth0:1 if you need an external IP on that box as well, but you must have them in that order: internal = eth0, externals, others eth0:1+…   Try that…   Matt PaperSoft     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of William Carlson Sent: Thursday, July 17, 2003 6:35 AM To: [EMAIL PROTECTED] Subject: [Asterisk-Users] Cisco 7960   I bought a 7960 it was running version 3.3 of the SIP software.  It worked fine. Me being the idiot I am upgraded to 5.1. Now it downloads the configs and then reboots. if I unplug the ethernet it doesn't reboot or if I remove all the lines in the SIP config it won't reboot. Since this is used cisco won't give me any support. For now I am running the MGCP version but eh asterisk seems to have some issues with it.    Thanks,      Will
