[cisco-voip] Emergency Responder Issue with Inbound Calls?

I'm about a month ahead of you. and had the same issue

you want your translation pattern to grab the 4 digits coming in and
translate to the 913XXXXXXXXXX.  not 913XXXX.  That was my fist issue.  then
make sure in CER that you still have it 913XXXXXXXXX and prefix remove 913.
I got all confused with this also as I only had 4 digits coming from the
Telco but CER is still expecting 10 digits.

Hope that helps.
