Hi Alex;

Nothing that I'm aware of. I suggest you check the configuration is according to the manuals.

It kind of sounds like the Mediatrix is going to sleep and being "awakened" by the first attempt and then allowing the second attempt. What codecs does the Mediatrix support? Maybe try changing codecs to the Mediatrix to see if smaller packet sizes help.

Good Luck,
