If you're just using the T1's for internet access it sounds like you just need to redirect what is coming into your office from the internet. &nbsp;It sounds like that is just mail. &nbsp;You probably don't have to change MX records just your A record. &nbsp;Your MX shouldn't point to an IP. &nbsp;It should point to an A record that point to that IP address that will be changing.

We are switching T-1's, same Telco, but we are physically getting new lines installed and we are going to have new Ip's. I have a concern that when we switch Mx records aren't going to be the only that needs to be changed. Can anyone tell me what I should be thinking about in regards to switching Ip's?<br />
<br />
1.We are going to have the router in front of our firewall<br />
2. We don't have anything specifically that points to our network from any clients<br />
3. We don't have Voip<br />
<br />
Thanks

Switching T-1's; what should I be considering when changing?

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.
