Couple of things to check:
1. make sure you dont have a firewall enabled on your PC
2. Make sure there is no firewall/ACL blocking RTP traffic between the networks
3. Make sure you have working microphone on your PC
4. If you have multiple NIC adapters on the PC, use the ethernet NIC as device name
HTH,
Chris

Set up a packet sniffer on the PC or laptop that you are using IP Communicator on. Use something like Ethereal. Set up a call and open the sniffer and look for any packets in the profile labeled: RTP. You should be able to set filters to isolate the RTP packets.

From the PC where you have the Communicator installed can you ping the recepeints phone's IP address or if they also have an IP Communicator their PCs?
Besides being a firewall/ACL issue it could also be a routing issue where the RTP stream has not path from you PC to the recepient.

I chased a problem like this for quite some time, then I stumbled on this forum post. If you are experiencing this problem with a Dell Laptop I would check it out.

This is an extremely old version of IP Communicator, have you tried upgrading to 2.0(2)?
