Nec SV8100 - Asterisk Sip Trunk

Hi, i’m having trouble with the sip trunk of these 2 .
I can call from the asterisk to NEC extensions, but when i try to call from a NEC extensions to anyone from asterisk i get invite, i send the trying and next thing i get is a CANCEL from NEC.
Anyone had this or a similar problem ?

I’ve seen some topics about the SV8100 but with old Asterisk versions and totally diferent problems

Here is the debug

The only thing in the Asterisk response to which it would be at all reasonable to object is the session timer request.

Can you explain ? I’m not too good with these
