voice bandwidth

How can we check the voice call bandwidth for VOIP in CISCO router using show command.

If you are using LLQ, you can use the show policy-map interface command:

You could also use a loop back address as th endpoint for the rtp stream and use the show interface command.

There is a voip bandwidth claculator availible here:

Thanks for your respond.

I using VOIP over Frame Relay, what I have configured was Frame Relay traffic shaping, RTP compression and IP Priority (no LLQ). What my consent is when I communicate over the VOIP is there any show command on the router that I can use to view the actual bandwidth used for the voice call (without any data).

unless the trafiic is classified, no. You will need to either use a pvc just for voice or configure LLQ. Other than that or calculating it by the number of calls, I can't think of any other way to see this.
