Hello,
I'm using third party VOIP PBX system in my company but i have Cisco IP Phones, I connect the PBX in DDNS so i can login in from anywhere. Now i have 2 new IP Cisco pones SPA502g & 8845 3PCC but it located in deferent location and deferent network. My PBX support the remote extension and i want to setup the Cisco phone so they can use the extension from PBX, I think i need to enter the DDNS domain in the phone but i don't know what is the process from the Cisco phones to connect to the PBX through the DDNS Domain.
For your help please
