VoIP avaya phones doesnt make registration/connection with Avaya IpOffice via a VPN
here the problem:
I have 2 sites with VPN using 2 sonicwall, a 170 and a 3060.
VPN are correctly setup and works.
something strange, when I use TZW 170 with standard OS, everything works perfectly.
When I use a TZW 170 with advanced OS, VoIp phones don't find the IpOffice.
I can send u capture of packets if needed.
Any idea ?
Thank you !
