IP Phone does not ring on incoming calls

Hi all,

after having solved several problem during an ip telephony installation (3 site 1 call manager in the main site + 3 srst on 2600 and 1760 router), I have now a problem that can look trivial, but I don't know how to solve it. One IP Phone in a branch site all at once stop ringing even if calls work. Sometimes resetting the phone it rings once and than no more. Sometimes it starts ringing after several seconds the call has come. Does anybody know what could be happened. The call manager version is 3.3

Tanks to all

Re: IP Phone does not ring on incoming calls

Just some ideas to try...

Check the device load. Make sure this phone is getting the same load as the phone that are working.

Can you change the ring type?

When it does ring, does it cut out? Could this be a speaker/hardware problem?

And I assume you have reset the phone to factory defaults? Have you made any configuration changes on the phone or does it get all info from the TFTP.
