Please try above commands and let me know.

Also make sure you have SRST configured for both SIP and SCCP in CUCM.

Also share the license details command output.

you should have uck9 permanent license.

Raaj

Dear Rajkumar Yadav

thank you for your reply


are you sure about cancel MGCP fallback and configure telephony service ?
and i sure have uck9 permanent license.

Hi,

I would prefer to configure the Cme as Srst configuration.

could you please confirm did the 7841 phones registered in Srst mode ?

Regards,

Raaj

Hello,

You are using SIP SRST. So you need to fill the SIP SRST IP Address in SRST Reference. Is this there?

If the SRST reference is right on CUCM, we should see an attempt from phone to register to router, which can be verified doing "debug ccsip message" [Look for REGISTER messages from that specific phone].
