Well, a valid point.

A lot will depend on just how dynaic the IP address is. If it rarely 
changes (typical of cable in the UK), then you just treat it as static. 
Use dyndns, etc. just in-case it changes, but when I had cable 8 years 
back it never changed for the 8 months or so I had it.

If it changes on a router reboot - typical of some ADSL services, then you 
may be able to use dyndns, etc., but you'll need to get your new IP 
address back into your asterisk box to use in sip.conf/externip= ...

If your ISP changes it on a whim, get a new ISP.

Alternatively, get a SIP account with a proper ITSP and have then register 
a number for you, then you just connect to them via SIP rather than have 
them rely on connecting to you.
