Troubleshooting dial-peers

Filed under: Router — ciscotips @ 11:15 pm

When troubleshooting dial-peers in a voice over IP (VoIP) environment, you can use the call simulate command to simulate calling to a dial-peer’s destination pattern (csim start number). This command enables you to verify that your dial-peer is configured properly, that there are no hardware problems, and that you are reaching the destination you want (provided that a ringing device is connected to the called port). For example:
Router#csim start number <number> where <number> is the destination pattern of the dial-peer you are testing


  1. Quick Question: What is a way to dial a number in a GW / Router that will verify the CALLING PARTY Number is being represented.

    Example: When I am in SRST Mode, I tell dial a phone which is supposed to be forwarded to VM. But when it forwards to UNITY it sees the forward number and not the incoming number. It then asks for PASSWORD instead of playing greeting.

    she was despised by Queen Bee Kristin, and Jason pulled the date and dash
    on her. In just a couple of months, Nikkole will be the
    mommy of two boys and with or without a man, that’s something to be extremely grateful and thrilled about. You’ll
    be able to help them satisfy their desire by letting them play dress-up games or make more than games.
