Cisco IP Phone "High Traffic, Try Again Later"

[Albert_Hernandez]

Hi 

I´m new on the forum, I hope you can help me.

In some Ip phones shows the message "High Traffic, Try Again Later" in happens only in sometimes and people who call a lot out the company, internal calls works fine.

Someone says it could be because the QoS, or maybe because the bandwith between that site to my main site. 

If you need more information I can give u. I am CCNA R&S I am new on Voice perdon If I cant explain sthg

I had an issue with this once and it ended up being a mis-configuration of my Location Bandwidth Groups.   If you have the Location Bandwidth Manager Service activated in Serviceability, then CUCM will monitor network metrics to determine if a call is possible based on the setting provided for the location that the phones belong to.   

You can test this by disabling this service to see if the error goes away.   If it does, then you need to take a closer look at the settings for Locations that are participating in Bandwidth Management.

off the top of my head, either system or device in the admin pages, then region/location.

you will have to look at the device pool of the phone first to see what region/location it has assigned. pretty easy to find though
