SX20 CUCM registration rejected

[Vassiliy Zatsepin]

Hello guys.

I have an issue with integration SX20 TC 7.1 with CUCM 9.0

CUCM registration rejected.

Provisioning CUCM checked.

There is error in application_log of SX20:

Sep 17 21:35:30.411 a8 appl[1583]: 7219.85 PROV I: [requestItem] Requesting http://XXX.XXX.XXX.XX:6970/CTLSEPe4c722676b41.tlv, state=ProvItemCTL (CTL requested)

On the SX20 I can see a message from troubleshooting tab:

ERROR: Provisioning Status

Provisioning failed: Provisioning is in an error state.

What can be a reason, any ideas?

Hello,

Have you found the solution? I have this problem too

[Vassiliy Zatsepin]

Hello,

For correct sip registration SX20 you need CUCM TelePresence Room license.

In this case i made h225 gatekeeper controlled trunk.

Hello, thank you, have read.

[sergey_karpiy]

Thanks for your help, guys

Suprisingly, but i found solution in factory reset and next reconfiguration of SX20

I've run into this before.

Deleting the factory installed certs seems to resolve it.

Configuration->Security->CUCM.

Delete the ITL and CTL certs.
