If you are using CUCM, then yes, you can use the "Enhanced" for the IP-Phones.

Thank you for your reply. CUCM is in a remote location. I want to connect a Cisco IP phone from another location. Both locations are connected through MPLS. Site A using Cisco 4331 ISR and CUCM and Site B using Cisco 4331 ISR.

Hi @Bothra Group,

Yes, you should be able to register phones at Site B to CUCM at Site A. Make sure that Phone subnet at Site B has reachability to CUCM Services.

How can i configure/register phones to CUCM which is available on remote location and both locations are connected with MPLS.

Two things, firstly why have you set your post as solved when you continue to ask questions on it? Secondly to answer your question about how to get a phone in your remote location to register to a CM at the central location you just need to put option 150 into the DHCP scope the phones uses to point it to the TFTP server(s) in your CM cluster. With that information the device will know how to connect with your CM to get its configuration.
