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

Locations

If a user gets a reorder tone after dialing a number, it could be because the Cisco CallManager bandwidth allocation for the location of one of the call end devices has been exceeded (less than 24k). Cisco CallManager checks for 24k available bandwidth for each device before making a call. If less than 24k bandwidth is available, Cisco CallManager will not setup the call and the user will hear a reorder tone.

12:42:09.017 Cisco CallManagerLocations: Orig=1 BW=12 Dest=0 BW=-1(-1 implies infinite bw available)

12:42:09.017 Cisco CallManagerStationD - stationOutputCallState tcpHandle=0x4f1ad98 12:42:09.017 Cisco CallManagerStationD - stationOutputCallInfo CallingPartyName=, CallingParty=5003, CalledPartyName=, CalledParty=5005, tcpHandle=0x4f1ad98 12:42:09.017 Cisco CallManagerStationD - stationOutputStartTone: 37=ReorderTone tcpHandle=0x4f1ad98

Once the call is established, the Cisco CallManager will subtract bandwidth from the locations depending on the codec used in that call. If the call is using G.711, Cisco CallManager will subtract 80k; if the call is using G.723, Cisco CallManager will subtract 24k; if the call is using G729, Cisco CallManager will subtract 24k.

Conference Bridge

Use the following information to help troubleshooting a “No Conference Bridge available” problem. This could be either software or a hardware problem.

First, check to see if you have any available Conference Bridge resources registered with

Cisco CallManager (either software or hardware). To do so, you can use Microsoft Performance to check the number of “Unicast AvailableConferences.”

The Cisco IP Voice Media Streaming application performs the conference bridge function. One software installation of Cisco IP Voice Media Streaming will support 16 Unicast Available Conferences (3 people/conference), as shown in the following trace.

One E1 port (WS-X6608-E1 card contains 8x E1 ports) provides five Unicast Available Conferences (max conference size = 6), as shown in the following trace.
