Voip not working

Anita,

Troubleshooting Cisco routers is an art in itself!

My suggestion is to debug the router in subject and use the debugging information in conjuction with Cisco's website to find out exactly what the problem is.

This is by far the best and quickest solution I have come to know from my experience.

We would though be interested in your findings, if you have the time to post them.

Good luck !
