Caller ID
dvijen:
My caller ID does not work connected to OBI for incoming calls on LINE interface but works on SP1, SP2, and PP interface. The settings on LINE and PHONE interfaces are default for caller ID. Any pointers to correct this? BTW caller id does work on another phone connected on parallel line.
Thanks

Try look at the Call History, to see if there is a call coming in from the Line port, with the correct callerID, it should show up under Peer Number.
Also, under Phone & Line Status page, take a look at "lastCallerInfo" on the Line Port column and see if the expected callerID is there or not.

well, I found the culprit. I had changed Ring delay to 1000 ms to enable phone ringing at the same time as the parallel phone. When I chenged this value to default (5500 ms), caller ID started coming through.
What I don't understand is why 5500 ms delay is required in Obi while my parallel phone picks up caller ID right away after first ring.

In order for OBi device to pass PSTN Caller-ID to the PHONE Port, it needs to completely decode the caller-ID signal prior to ringing the phone. The ring delay is to make sure OBi has enough time to do this. This is also needed in order for OBi to perform caller-ID based inbound call routing. For example, you might not even want to ring the phone for certain callers.
For US, Caller-ID is sent shortly after the end of the first ring. So potentially you can adjust this delay parameter to about 3000 ms (which is counted from the beginning of the first ring). If that works for you reliably, you can stick with it. The default value is conservatively set to 5500ms to make it work for most PSTN services out of the box.

I understand it now. I tried all the values from 100 to 5000 in the increament of 500. None of them worked. First one to work was 500 (default).
