hi we are working on a uc540 at the office, and we are trying to configure a sip trunk on the wan port. first question : do we need to configure the wan port with the ip address the sip provider gave us? or an address on the same network ? 2nd question : where are we suposed to use the default gateway of our sip trunk router? exemple : my sip trunk provider gave me the address 172.28.24.57 255.255.255.248 do i need to configure the wan port where my sip trunk is connected to it with the this address? do i need to do something on my voice vlan? i am currently able to receive call but when i pick it up, the call end and if i try to dial out, i get a busy tone thx
