Hi,
I am using UC520 for testing. We have analog central. 2 lines are coming to my fxo port from that central. They are internal numbers.
Analog central 111 - and 112
When someone calls 111 (voice-port 0/1/0) my ip phone rings which is 241 on uc520
When someone calls 112 (voice-port 0/1/1) the other ip phone rings which is 242 on uc520
That's ok. This is the configuration I am using.
Problem is:
It is working but after a couple a days passes, I can not dial any number on analog central but I can dial numbers on UC520.
When I check the analog central, the lines seems busy which they are not. After I shutdown and no shutdown fxo ports they start to work again but for sometime it happens again.
Is this problem with UC520 or analog central?
voice-port 0/1/0
trunk-group ALL_FXO 64
cptone TR
connection plar opx 241

!
voice-port 0/1/1
trunk-group ALL_FXO 64
cptone TR
connection plar opx 242
description Configured by CCA 4 FXO-0/1/1-OP
and the caller-id seems not working too but I think it is because of the analog central
Thanks

Regarding the FXO disconnect problem, here are a couple of things to try:
1. Make sure that your cp tone is correct. You can create a custom cp tone if the defaults do not meet the telco's standards
2. Add "timeouts call-disconnect 5" to the voice port
3. Add "timeouts wait-release 5" to the voice port
Regarding caller ID, add "caller-id enable" to the voice ports
Hope this helps.

Thanks Brandon. I added timeouts to voice ports.
For the caller-id enable command, when I use it. voice port is waiting for the caller id. After the 2nd beep tone the ip phone starts to ring (with no caller id). So I cancelled that because of the ring delay.

Sounds like the telco is not sending caller ID. Check with them to make sure it is enabled on this line.
