So if you can tell me where this is wrong as per 2833 and the clarification via 4733 ? rfc4733 obsoletes rfc2833 and says this: The special duration value of zero is reserved to indicate that the event lasts "forever", i.e., is a state and is considered to be effective until updated. A sender MUST NOT transmit a zero duration for events other than those defined as states. The receiver SHOULD ignore an event report with zero duration if the event is not a state. /b PS: http://www.rfc-editor.org/rfc/rfc4733.txt On Jun 28, 2008, at 11:10 PM, UV wrote:
The only page I found on UM is http://wiki.freeswitch.org/wiki/Exchange_2007_UM and even there it’s stated “bypass_media_true was used because DTMF was not interpreted by FreeSWITCH (bug ?)” so I guess they couldn’t make it work as well.
In a working scenario (using SJPhone) the Event Duration starts from 0 (in the first packet) and then 160, 320, 480 and so forth until three identical packets of 2280. In the non-working scenario (no pass though), it’s exactly the same but without the first packet of Event Duration 0.
