Default SIP phones: "growling" or muffled ring tone


We are experiencing an odd behavior that I am trying to troubleshoot. On one floor of our office building the suites get a "growling" or muffled ring tone, and a delayed Caller ID. Sometimes the calls will not complete.

When we trace on the network and with the carrier, we cannot any obvious errors. Since we are using TLS, I cannot see the details on the SIP transactions.

Has anyone seen this occur and how were you able to fix it?

Kind Regards,
Sr Telecommunications Engineer
