Error-Level Alarms Chapter 6 Cisco Unified Serviceability Alarms and CiscoLog Messages between IPv4 and IPv6 packets), or multimedia capability (if a call involving video and/or data in addition to audio requires insertion of an MTP or transcoder then the MTP/transcoder which supports multimedia will be inserted).

Check the user manual of the configured MTPs and transcoders to see whether they support RSVP functionality. If none of them support RSVP functionality either they need to be upgraded (if upgraded version support RSVP functionality) or additional MTP or transcoders need to be installed which support RSVP functionality. If the RSVP Agent (MTP or transcoder) allocation is failing due to a capability mismatch, it's possible that the media device does not support the requested capability (such as IPv4 to IPv6 conversion, passthrough) or the capability might not be configured in the device. Please check the user guide and documentation of the media device to make sure that device supports all the necessary capabilities. Also, caution should be taken care if all the MTP or transcoders are configured with all the supported capabilities. There are certain capabilities (such as RFC 2833 DTMF or RFC 2833 DTMF passthrough or passthrough) which could be supported by most of the MTPs or transcoders and there may be certain capabilities (such as IPv4 to IPv6 conversion and vice versa or RSVP Agent functionality or Transfer Relay Point or multimedia capability) which can be supported by only by a single MTP or transcoder depending on the devices that you have. For example, you may have end devices belonging to different locations and may need to reserve the bandwidth only between two locations; calls between other locations may not need to reserve the bandwidth. Now, suppose all the MTPs or transcoders are configured with all the supported capabilities and only one MTP/transcoder supports RSVP functionality; if this MTP/transcoder is configured with all the supported capabilities (which all the other MTPs or transcoders in the same MRGL or default MRGL also support) it may happen that this MTP can get allocated for Transfer Relay Point or RFC 2833 DTMF or RFC 2833 DTMF passthrough or passthrough instead. As a result, when a need arises to reserve the bandwidth (which other MTPs or transcoders in the same MRGL or default MRGL do not support), all the resources of this MTP/transcoder may be in use and the RSVP Agent allocation may fail. 6-180 Cisco Unified Communications Manager Managed Services Guide OL-22523-01
