<div></div>About H.264 plugin - actualy I have 3rd party static library for
H.264 encoding/decoding and use H264 plugin as wrapper to connect library to
h323plus. I don't think anyone has interest of half working plugin without
static library...<br><br>

problem is caused by an master/slave conflict when first opening the audio

processšis to renegotiate the OLC. It appears that the T1000 cannot
properly renegotiate the OLC and incorrectlyšallocates an

(increase 1 after each reject).<br><br><br>
