We are in the process of deploying a UC520. We are trying use this with 4 pots lines connected to our FXO ports. I was wondering if I could get some help from the community on this one.
Problem is that the fxo lines don't work. We started with a default config, used the setup wizard in cca version 2.1 and did the basic config. We can make internal calls, but the external calls don't work. I am attached the debugs from a failed call. the debugs are the result of the "debug voice ccapi inout" command. If you look into the debugs, you will see that the called number is blank. I thought that this might have something to do with translation rules, but it didn't appear that the translation rules were wrong.
I am also attaching the config. This config file is the configuration as done by CCA after the initial setup wizard - nothing was changed.
Sometimes it works. It seems that we can reboot the router and it might work for a call or two after it was rebooted. So, it's very intermittent. I wasn't able to get it to work again and collect debugs on a successful call.
Also, there is a very long pause and then it rings and then it says that the number can't be reached. I can get the exact verbage if it matters.
Also, the inbound calls are consistently successful. Successful in that we call in and get the tone for the autoattendant.
Any assistance would be greatly appreciated. We are trying to get the customer to by smartnet so we can call it into the TAC and/or upgrade the CME/IOS/CUE. But, in the meantime we are trying to figure it out on our own.
Is it possible that there could be a hardware problem? Are there any configuration parameters related to an FXO port that could cause this? I always thought that FXO was pretty straight forward.
In your dial plan on CCA, remove any of the dial patterns that mention 7 digit dialing and see if that helps. The dial peer that was used is a 7 digit dial peer which doesn't sound like it will work for you.
I will look into your configuration in more detail, but what you describe seems to indicate that calls are probably being routed out of FXO ports that are not connected. Are all the FXO ports on the UC500 being used? If not, could you try configuring Trunk groups from the outbound dialplan settings?
