Recommended Action
If you did not expect to exceed the number of devices and you have auto-registration enabled, go to
Device > Phones in Cisco Unified CM Administration and search for phones starting with "auto". If you
see any unexpected devices which may not belong in the system (such as intruder devices) locate that
device using it's IP address and remove it from the system. Or, if your licenses and system resources
allow, increase the value in the Cisco CallManager service parameter, Maximum Number of Registered
Devices.
RsvpNoMoreResourcesAvailable
RSVP Agent resource allocation failed.
The alarm occurs when allocation of an RSVP Agent fails for all the registered RSVP Agents (RSVP
Agents are basically MTPs or transcoder devices which provide RSVP functionalities) belonging to the
Media Resource Group List and Default List. Each RSVP Agent may fail for different reasons.
Following are some of the reasons that could cause an RSVP Agent allocation to fail: available
MTP/transcoders do not support RSVP functionality; a capability mismatch between the device endpoint
and MTP/transcoder, codec mismatch between the endpoint and the MTP/transcoder; a lack of available
bandwidth between the endpoint and the MTP/transcoder; or because the MTP/transcoder resources are
already in use.
A capability mismatch may be due to the MTP/transcoder not supporting one or more of the required
capabilities for the call such as Transfer Relay Point (which is needed for QoS or firewall traversal), RFC
2833 DTMF (which is necessary when one side of the call does not support RFC 2833 format for
transmitting DTMF digits and the other side must receive the DTMF digits in RFC2833 format, resulting
in conversion of the DTMF digits), RFC 2833 DTMF passthrough (in this case, the MTP or transcoder
does not need to convert the DTMF digits from one format to another format but it needs to receive
DTMF digits from one endpoint and transmit them to the other endpoint without performing any
modifications), passthrough (where no codec conversion will occur, meaning the media device will
receive media streams in any codec format and transmit them to the other side without performing any
codec conversion), IPv4 to IPv6 conversion (when one side of the call supports only IPv4 and the other
side of the call supports only IPv6 and so MTP needs to be inserted to perform the necessary conversion
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).
