Hi SYRX and welcome to the business forums.


If you need assistance with adding a static to your account, I can certainly assist. However, due to our demarcation policy, I wouldn't be able to advise if your personal equipment would need a static address. If you would like me to add a static, please private message me your full name, the name of your business, the full service address and the phone number associated with your account.
