I have a 7100 running the phone system and 706 phones connected to them. I had an issue where on one of the phones, the caller sounded garbled to a point where you couldn't understand what they were saying. The end user on the 706 phone sounded fine. The settings for all the phones are the same, I tried a different fxo port, and plugged in a different phone. The different fxo port did not make it better, but a different phone sounded fine. Therefore, I began looking at the phone as the issue. so I tried to move the user to the new phone that was working fine. The problem I am having is that the phone won't register. I don't even see it trying to when doing a debug SIP stack message register command. I only see the other two working phones. The phone gets an IP, but nothing happens. I've deleted the phone and the user, re-added them both, and reset the phone as well. Everything looks right in the config, but I am stumped as to why it won't register. If any one can help, it would be greatly appreciated. Thanks.
Thank you Jay for your reply. I will try. the issue is this site is remote and I don't really have a device to capture the mirrored traffic. I'll see if our site has something, and if they do, I'll get that information and see what I can find. Thanks.
Is the phone getting an IP address from the Voice VLAN or the Data VLAN? If it's getting an IP address from the data VLAN then either there is a problem with the DHCP options or the phone needs to be manually configured to the voice VLAN. If it's getting an IP address from the Voice VLAN it maybe an issue where the phone didn't redownload the config after you had changed it from a test number to the actual user. The easiest way to deal with that is just factory default the phone. You can run a debug of TFTP or FTP which ever method your using and see if the phone downloads everything properly. You can also run a debug of DHCP if the 7100 is giving out DHCP to make sure the phone is getting a proper DHCP IP. You can run these debugs remotely without a packet capture, if all other phones are up and running the results of the below debugs should be just the phone in question. You can remotely reboot it by shutting down the port it is connected to and then turning it back on. A packet capture would be the best option as it will show everything but if its not possible then hopefully this might shed some light at least.
debug ip ftp-server
debug ip dhcp-server
debug tftp server events
Thank you for responding. This issue is driving me nuts. The phone was on the system for another user account. All I tried to do was to change what user account the phone was associated with. I'm certainly no expert at this system, but it seemed simple enough. It is getting an IP from VoIP pool that is set up. After I deleted both the phone and user and then re-added them, I had someone factory default the phone. Still no luck. I will try it again with the debugs you sent me and report back. Again, thank you for your response.
Did you delete the user account the phone was originally configured for as well as the phone for that account. It sounds like the phone is not getting the proper config file possibly because there are more then one for the phone. You may want to go in and delete all instances of the phone, and all users that have had that phone assigned and then recreate just the one accurate user. Might be worth throwing in a factory default on the phone once they are both deleted before recreating the new one.
I deleted everything. one thing i can't remember is if i factory defaulted before recreating them or after. i will try that to make sure it's done. Thanks.
I deleted the phone and the user, and then had someone factory default the phone. I then created the phone and the user, but still no luck. I am seeing the phone get its IP from DHCP, but I am not seeing anything about registering when running a debug on the SIP stack. I also tried a debug on the TFTP, but nothing came up. I guess my next course of action will be to somehow try and wireshark the phone.
You may need to FTP to the 7100 and go into the ADTRAN folder and delete the adtran_<mac address>.txt file for the phone in questions, then rebuild the account.
I will be out of the office and returning Friday February 24th. Please
call 207-326-2240 if you have an issue that needs immediate attention.
