this behavior looks alot like cisco bug CSCdz77783: --------------- When a 7960 IP phone using SIP, makes a call to a device like a media server which starts playing the immediately after answering the call, a clipping of first couple of words may be noticed.
There is no known workaround for the problem. --------------- the release notes claim that this was fixed in 5.1. i still see it in 5.3. On 2003.09.12 11:24:43 +0000, David C.
