IP Phones Busy system. Try it again later , on CUCM 11.5

[cristian.munoz]

Hi All

I have a new installation for a new CUCM 11.5. I have ten IP Phones for test, a ICT for the CUCM old and a H323 GW for PSTN,  and they have in some times the message "Busy system. Try it again later".

Any idea for extract a log o debug for to see what happens?

TIA

I remember system saying High Traffic Try Again Later, this will happen if location settings are configured to allow only a few calls based on the codec and bandwidth settings.

In your case try changing location setting and see if it resolves.

In addition to what Haris is suggesting, can you clarify if you receive this message even if you place calls between the phones that are registered to the new CUCM?

Hi George

If your old CUCM version is greater the 8.X, can you replace the ICT between the 2 call Managers with a SIP trunk and try again?

Dear George

Good idea, I´m going to replacement the ICT for a SIP Trunk between the CUCM´s.

I´ll check the Monday. Good weekend.!

SIP trunks are only recommended for 8.5+, anything below 8.5 is still recommended to use ICT

In this case is CUCM 11 and CUCM 9.1.

I All

I think I have found the source of the problem.

With the Trunk in SIP, I was able to review the logs of the calls and I noticed that every so often the SIP message "483 Too Many Hops" appeared and corresponded to a number that did not exist. Then, both CUCM delivered the call and entered a Loop.
Now my question is whether it is possible to do loop control in the SIP Trunk?

TIA
