How do I disabled SIP ALG on a Cisco 881 router?

I have a newly installed router (881) and my VoIP vendor (not Cisco) is requesting that I disable SIP ALG (SIP fixup), but I can't find the correct syntax. Any Help?

This should do the trick for you:

no ip nat service sip udp port 5060

Also, make sure you don't have any "ip inspect name xxx sip" in your configuration.  In this case, "xxx" could be anything.

How do I add a port range in that syntax?

There isn't a range syntax, but you can add new ports with repeated entries. SIP generally doesn't use more than one or two ports, so it shouldn't be a problem.
