Hi,
It's more than likely these people are getting this message due to bandwidth (CAC) settings configured in CallManager.
In CCMAdmin, go to System > Service Parameters > "choose your server" > then choose Cisco CallManager (active).
Scroll down to Clusterwide Parameters (Device - Phone) and check the "out of bandwidth text".
Depending on your preference you could increase the CAC bandwidth via the location configuration (System > Location).
Hope this helps. If this isn't it, let us know and I'll have another think.

Thank you for your reply, unfortunatley this issue is not related to bandwidth, all this calls are to PSTN, the call manager and Gateway are in the same LAN, besides that the Messages of out ouf bandwidth is "Not Enough Bandwidth" and not "High Traffic Try Again Later"

Sorry, I assumed you were making calls over the WAN and someone had changed the message.
As per the documentation you have already found on this problem for 3.x and 4.x, have you checked the code yellow configuration in the CallManagers enterprise parameters (Cisco CallManager (Active) service) to make sure it is set to the default?
I can't find any bugs related to the version you are using. Has this only just started happening? Also, what signalling/call control protocol are you using (SIP, MGCP)?

We are using SCCP for the phones, this start happening after the upgrade from 4.1(3)sr7 to 6.1(2), i was monitoring the Performance Counters of CallRejectedDueThrottling in each 3 servers and didnt find anything.

Hello,
This apply to any CUCM version when we have a
Call Throttling situation
Check this:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/6_0_1/ccmfeat/fsclthrt.html
The most common situation ia call loop,normally when we have PBXs attached and a route pattern is pointing to cucm and also from cucm to pbx...this normally requires more analisys

verify that there isn't a route loop somewhere. Check the Real-Time moniotr application logs.

Using Performance Log, i didnt see any Code Yellow Alert, and any CallRejectedDueThrottling
What kind of message i'll see in application log if there is a route loop?

Within RTMT open up the specified server and add the performance log for
Call Manager System Performance\ThrottlingSampleActivity
&
Call Manager System Performance\
QueueSignalsPresent 3-Low.
If you start seeing Queue signals you are going to be getting close to a Code Yellow.
Other things to look at are physical machine performance.
Disk I/O. Make sure all logs and traces are going to the log partition (F:) and not going to the root OS drive.
Check Server Physical Memory as well.
Any and All of these can and will lead to the High Traffic error.
Call Routing loops are a big problem with the Throttleing levels.
