I have a very strange problem with callerID from my PSTN.
The lines from the PSTN is connected to a vic2-2fxo card. I PSTN has callerID enabled which I can see whenever a caller calls on the telephone box but when the line is placed on the fxo, it does not display on the IP phones.
When I connected another line from a different PSTN, I get callerID displayed on the IP phones.
When I debug, the vic receives request for the callerID and displays a lenght error for the callerID and displays callerID failed.
PSTN does not know what to do as they're sending callerID.
I'll appreciate everyone's input on this with a fair rating.
I finally got it resolved. I still believe its a bug in the IOS.
I'm running CME4.0 on 2811 but since the 2811 didn't have DSPs, I had to install FXO on 1760V that had DSP chip. This was how the problem started with CallerID working with some PSTN while it didn't work with other PSTNs.
The problem got resolved after I installed PVDM2 on the 2811 and moved the FXO card to the 2811.
The problem does not have anything to do with MGCP or ISDN.
I won't say this really fixed the problem. For the scenario I was having, this fixed it. We might not be having similar problems but if you can explain the CME deployment with the devices used, I might be able to assist.
What type of VIC are you using?
Is your PSTN sending callerID and if yes, have you confirmed?
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
