Hi
Issue after upgrade to V11 from V9.0
I have SIP trunks coming in on LAN1 and I have Avaya 1600 series handsets on LAN2. Handsets can make and receive external calls no problem and call handset to handset without an issue when they are on the same LAN. Due to the setup there is a small amount of extensions that need to be on LAN1. When I try to call from these handsets to handsets on LAN 2 they ring each other but there is no speech.
Pre upgrade this worked fine does anyone have any suggestions.
Thanks
