===========================

What you may need to modify

===========================

If you are using the hostname of any of these servers (e.g. sip.icttech.net), there are no interventions required on your part. However, if you have concerns regarding the transition and you want to make sure that there are no issues when the DNS is updated with the new IP address, please reboot your router/device after the IP switch is done. If you are using a Softphone, like Zoiper or X­Lite, a restart of the software may be required.

If you are currently using the IP address of any of these servers to connect directly to them instead of the hostname (e.g. 184.75.213.210 instead of sip.icttech.net), please update with the new IP as the IP switch is completed. (It is not recommended to use an IP Address directly with ICT Tech)
