A single site reports that when they dial select numbers, the call connects, but they do not get audio. The administrator finds that the calls are not routing out of the normal gateway but out of another site’s gateway due to a TEHO configuration. What is the next step to diagnose and solve the issue?
A. Verify that the route pattern has the correct calling-party transformation mask.
B. Verify that IP routing is correct between the gateway and the IP phone.
C. Verify that the dial peer of the gateway has the correct destination pattern configured.
D. Verify that the route pattern is not blocking calls to the destination number.
