1. Check network connectivity using “ping.”
2. Check network firewall settings. See “Network Configuration Guidelines for VoIP” on page 299 for details.
3. Check the IP address of the destination system.
4. Check the RTP and RTCP settings. Make sure UDP port numbers 49152-49199 are not assigned to other
applications. RTP/RTCP stands for Real-Time Transport (Control) Protocol, a transport protocol for real-
time applications used to transport packetized voice packets over the IP network.
5. Check the IP Dialing Table in Enterprise Manager for Server ID Length. Refer to “Defining the IP Dialing
Table” on page 322.

is a workgroup pilot number or has Multiple Call Waiting enabled, the caller is placed on hold and hears
ringback or music.
