How to view software MTPs

Unanswered Question

Hi guys, we have a SIP trunk from CUCM to a Genesys contact center server.


Is there a command to see how many mtps are being used and how many are available?


We are getting some failed transfers and a "resource unavailbable" error message, but we are unsure exactly which resource it is referring to.


Thanks as always,

TB

Software MTP utilization can be checked through the Real Time Monitoring tool ( RTMT ) while ios based mtps can be checked by running "show sccp connection" on the router on which they are configured.

To add to Manish's suggestions, the CUCM command line can be used too, just remember that some of these would have to be run per server.


show perf query counter "Cisco Media Streaming App" MTPStreamsAvailable

show perf query counter "Cisco Media Streaming App" MTPStreamsActive

show perf query counter "Cisco MTP Device" OutOfResources

show perf query counter "Cisco MTP Device" ResourceActive

show perf query counter "Cisco MTP Device" ResourceAvailable

Infact it looks like that the number of MTP resources that are free are quite less when we compare it to the number of MTP resources active. MTPstreamsActive is pretty high and MTPstreamsAvailable is pretty low, which means a few more calls and the MTP resource unavailable message could come up. Try running these queries during peak hours to get a better picture.

Thank you Manish.  I was afraid of that.


Do any of you know how I could kill these MTP streams other than rebooting the CUCM servers.


We enable MTP on a SIP trunk to our Genesys server.  I would need to disable that setting and then will the MTP's drop on their own or will I need to reboot or doing something else to clear these up?


I owe all of you so very much.

Tracee,

The MTP utilization will drop automatically of you uncheck the MTP field on SIP Trunk, you just need to reset the SIP trunk. However, you need to verify if unchecking the MTP box results in a call failure. If the calls fail then you will need to look at the option of adding IOS based MTPs or adding more MTP resources from a diff callmanager server in the MRGs that are included in the MRGL of the concered device / trunk. If you are unsure about these settings you can open a TAC case to get specific inputs.

Whether you are hitting that bug will depend upon your callmanager version and will also need to be verified through traces, TAC would be able to confirm this for you.
