We're trying to configure secondary SIP PBX for the Icon 600 already paired with the Lifesize Cloud infrastructure. But we've got a little problem, because our SIP provider using the same signaling ports (5060/5061) like the Lifesize Cloud. I tried to use these ports, but I always ended with error: "Invalid parameter." Provider port will not change!
Do you have some workaround for this case? Thank you very much.
