Hello
I’m having a peculiar problem with some Cisco 504 phones/extensions and UC560. I wonder if it could be licensing related.
We have 3 phones (extensions 106, 108, 111) that often loose dial tone and can’t forward calls but inbound and outbound calls work! On UC560 we can’t see any problems, “show ephone” confirms that all phones are operational. If we reboot these phones – they work fine for a day and then stop working all together. LCDs on the phones don’t show signs of a problem either, it’s just weird when pick up the phone and there is no dial tone, but it works! We tried changing the phones – didn’t help, so it appears that these three extensions have something wrong with them, but the config is the same for all phones.
Initially we started with about 14 x Cisco 504 phones and the system has been working great for a year. Then we added a number of IP phones for remote teleworkers connecting over VPN
Remote workers work in a different time zone and not all at the same time, but on some occasions we had more users trying to connect than we had licenses. We have 22 user licenses and on some occasions we had 23 people trying to connect (504 + IP) so 23rd was refused connection.
Could this problem have anything to do with licensing i.e. if more users trying to connect the system kicks out somebody else?
How can I get to the root of this problem?
