No, the Touch 10 initiates the pairing with the codec, not the other way around. I'd recommend reserving IP addresses in your DHCP server for your endpoints so they don't change IP's. That's what my company does and we never have this problem.
I would suggest setting both the endpoint and the touch 10 as static IP addresses so that they are not changing. Otherwise you would connect the touch 10 directly to the endpoint (instead of going through the network) to get around this issue. It is also usually best practice to set static IP addresses on items like this for manageability.
