Cisco IP Telephony Troubleshooting Guide for Cisco CallManager Release 3.0(1)

Documentation Checklist

Use the following checklist to be sure you have the proper documentation on your network topology.

∙Topology that shows all network devices and critical components with port/interface numbers to which they are attached, and what VLAN (if applicable) to which they belong. Special designations should be used for ports that are in trunking or channeling mode.

∙The root of the spanning-tree should be configured and all normally blocking ports should be identified.

∙Any WAN circuits should be identified with the amount of bandwidth (CIR in the case of frame-relay).

Note: The Cisco IP Phone 7960 has a 10/100-switched network port and a 10/100 PC port. Cisco does not support “cascading” phones off of the PC port. We do not recommend attaching both the network and PC ports to a switch (thereby creating a physical loop in the network).

Any WAN interface will require special consideration, since this is a potential source of congestion. Cisco IP Phones and gateways set the RTP stream IP precedence field to five, however this only tags the RTP packet. It is up to the network administrator to ensure that the network is configured for prioritization and call admission control so that the Voice over IP (VoIP) traffic can be serviced with minimal delay and contention for resources.
