Updating port designation on Cisco 1605 for IP Phone

[kegger101]

We are in the process of adding a number of IP phones for home based employees, is there a way we can configure the router to accept a range of ports instead of inputting every port as the phone is updated? Currently we look like this

ip nat inside source static udp 10.1.1.220 12288 20x.222.222.105 12288 extendable

ip nat inside source static udp 10.1.1.220 12289 10x.222.222.105 12289

the ports run from 12288 to 12303 and there is another list.

Is there a short cut?

Thanks
