Phones Suddenly get URL call is disabled
tommy...@gmail.com
a handful of our polycoms suddenly became disabled with the error message 'URL call is disabled'. but when i put one of these phones on my home network, it works and is connected to the work PBX. i think what is going on is that the phone cannot find the boot server and uses the existing configuration (which does work).
i tried reformatting a couple of the phones, deleting the config files on the boot server (basic sipxcom setup), and starting anew. no luck. these phones do pick up an IP address via DHCP but seem to not even touch the config files on the boot server.
thanks for any suggestions you may have...

Are they possibly being blocked by iptables? I've had this happen before and I added the local network subnet to the White List and it stopped.

Doesn't matter. I have the same situation try iptables -L -n -v | grep 192.168* or whatever your network subnet is

Are the .122, .79, .134 and. 137 addresses on your private network? Try adding your private network to the firewall white list in the format 10.0.0.0/24 or whatever your subnet format is. Apply it and wait for configuration deployment to finish. Plug the phones in and see if they come up

hmmm. i can check but probably not as the PBX is on its own LAN and all the phones are on this LAN. i brought home an offending phone just to test it out from outside the PBX LAN.

1. delete the mac address from the dchp server
2. take the ip address out of the pool that was assigned to the phone
3. plug the phone back in and it is assigned a new ip address
4. phone is now able to make calls and no more URL disabled
I have linked this happening due to lack of use. This usually happens on phones that are not used on a regular basis.
To me, this is a band aide fix, still trying to figure out exactly why this happens, but this is the fix I have found to work in the interim.

Or someone plugged a device onto the network that is handing out DHCP, and doesn’t include your Option 66 or SRV records.
Also, check security. As a matter of habit, I always change system/security Block DoS attackers to ban time 15, max retry 3, find time 60. There as an old bug in Polycom phones where their behavior looked like a Denial of Service attack. The default setting ban those phones from being able to register again once they meet the requirements of the rule. Those changes keep it from being a permanent BAN.

In my experience it tends to be a duplicate IP on the network. Mostly because of poorly configured DCHP servers or maxing out their scope.
