Troubleshooting - Common Symptoms and Solutions
The following are some of the most common problems you may encounter
and a list of steps to troubleshoot and resolve these problems.
Poor Voice Quality
When voice quality is poor, try the following:
1. Perform a Loop-Back Test - Call yourself by dialing out and dialing
back into yourself. If you don’t have any problems performing this
test, the problem is most likely in the network or at the remote site.
2. Check Traffic Between AltiWare IP Stations - Open the IP Trunk
Current Traffic Statistics window and the AltiWare IP Cumulative
Traffic Statistics window in AltiWare Administrator or AltiAdmin to
view network traffic.
3. Check the RTP and RTCP Settings - Make sure UDP port numbers
49152-49199 are not assigned to other applications. RTP/RTCP is the
acronym for Real-time Transport (Control) Protocol, a transport
protocol for real-time applications used to transport packetized voice
packets over the IP network.
4. Check Network Configurations - Follow all network configuration
guidelines provided under “Network Configuration Guidelines for
VoIP” on page 48. Make sure the router, WAN bandwidth and Jitter
Buffer are configured properly.
