Hello , i have 2 Cisco 7937 with version 1-4(4) apps37sccp.1-4-4-0 , one register with CUCM and works well, and the other don't.
I have a cluster with 2 Servers:
CUCM VERSION: 18.104.22.16800-5
Booth register in SUB
7937 that works:
This is in my local LAN
7937 don't works:
This is in a office over the internet
The phone shows in dilpay " registering" and never register.
I see in wireshark RegisterRejectMessage.
The phone access coporate directory , and also assumes phone language.
In call manager i see the ip but the state is "REJECTED"
Anyone had the same problem or can help me on this problem?
In RTMT i see this:

Thank you! We ran into this very problem last week, and this post hit the nail on the head! Very frustrating, especially since we had cut 3 other remotes with no problem, phones registered even with inpect on in firewall, although it took a long time. Those remotes were also higher bandwidth, our failing site was our first T1 connection, and could not get a single phone to register. Showed rejected, and CUCM trace showed this reason code:27. Deactivated sccp inspection in their Juniper firewall, and all came right up.
Cause 27 Explanation:
"CapabilityResponseTimeout - (SCCP only) Unified CM timed out while waiting for the device to respond to a request to report its media capabilities. Possible causes include device power outage, network power outage, network configuration error, network delay, packet drops, and packet corruption. It is also possible to get this error if the Unified CM node is experiencing high CPU usage. Verify that the device is powered up and operating, verify that network connectivity exists between the device and Unified CM, and verify that the CPU utilization is in the safe range (you can monitor this via the CPU Pegging Alert in RTMT)."
" Recommended Action
Investigate any network connectivity problems in the system. It's possible that you have reached the maximum number of devices; the Cisco CallManager service parameter, Maximum Number of Registered Devices, controls the number of devices allowed in the system. After taking licensing, system hardware and other related concerns into consideration, you could increase the value of the service parameter. Also, refer to the reason code definitions in the alarm for additional recommended actions. No action is required if this event was issued as a result of a normal device rehome. "
Do you have any connectivity issue between this site with main site? An firewall between this networks?
There are other IP Phones on this site that are registered with CUCM?
