[AG-TECH] Re: XAP full duplex issues

[Natalia Costas Lago]

I noticed running a node against a PIG and a node against another node, but 
the other node has our XAP configuration (we are helping them with their AG 
node.

Both can notice the distortion, but it is easier to have a third person 
connected for him/her to realize about the problem.

Yeah, u can notice on rat the dropouts, when i speak steadily (saying one 
vowel for a few seconds for example) and the other person speaks at the same 
thime, i can appreciate the behaviour in rat.

I am guessing about the problem, and I made a few changes in our 
configuration. I would really be interested in testing if you can.


I'll be available the whole day (till 15:00 - UTC +1). Or we can test next 
week (I have an AG session in the afternoon, we can test it before or 
after).

Kind regards,
Natalia.
