Description (partial)

Customer is unable to page to 7937 phones when there are calls in progress on 7937 phones. They have have tried this functionality and it works on the 7940, 7945, 7962, and 7970 running SCCP and 8831 running SIP. When they try this with the 7937 it does not work. If there is not a call in progress on the 7937 it does work fine.

Issue is occurring on firmware versions later than 1.3(2).

We downgraded the 7937 phones to the following firmware versions, but the issue still persists:

Does not affect 1.3(2) firmware
