You need to configure the UC500 correctly for the phones to register.

Dear khurram,

Thank you for reaching Cisco Small Business Support Community.

Below you can find a document with a configuration guide to register the IP phones and generate the CNF file on the UC540 device;

Thanks paolo if i am not configuring the phones correctly than why i am having problems with two phones only? other are registered here..

Thanks jaffret for ur kind response.

i have exactly doing the same configuration as in document but my one phone SPA 504G is getting different errors, sometime it stuck on Initializing network and sometimes on "downloading mac.cnf.xml" it remains in this state.

Hello Khurram,

It looks to me like a hardware failure, so I suggest you to get in contact with the Small Business Support Center to confirm;

https://www.cisco.com/en/US/support/tsd_cisco_small_business_support_center_contacts.html

Please let me know if there is anything I may assist you with in the meantime.

Thanks again,

Hello Khurram,

Jeffrey makes a valid point, either you have faulty handsets or their operating system has become corrupt.

You can either try and reset the units back to factory defaults and then plug them back into the phone system (Best to do this off a power pack with the SPA phones) and then have the phones attempt to reinitialize themselves again.

Or you can just contact SBSC and have them guide you over the phone, and if the issue still remains they can assist you with the RMA process over the phone.

Cheers,

David Trad.
