OXO R4.0 032/001 BUG with MIPT310 ?????

[eltorio]

Hi,

I found something very strange…

I setup a MIPT310 on my OXO, it has the internal number 111,
I also setup two 4068G they have the number 100 and 101

111 can call 100 and 100 can call 111, OK
same with 101

Now I put 111 as the secondary set of 100

From 101, I call 100…
100 and 111 are ringing
I pickup 111 (the wifi mobile)
Error no sound…
I can transfer etc. but no sound in each way

Idem two can't have a voice channel between them, if one mobile call another it rings but after picking up the phone there is no sound.

Is it a misconfiguration or is it a bug?
