Is there an option to specify a stun server in those IP phones? <br>

Greetings all,<br><br>A couple of clients have recently decided they'd like extensions to their<br>office PBXs at their homes, so they've duly been provided with preconfigured<br>phones which register with the Asterisk server at their offices (public IPs)
<br>quite happily.<br><br>Every 3-5 days it seems that these remote extensions lose their registration<br>and are no longer accessible from the asterisk server. In all cases,<br>power-cycling the phone solves the problem immediately by forcing the phone
<br>to re-register with the correct IP. The users in question have ADSL in their<br>homes with a standard consumer router (Netgear DG834), on a semi-dynamic IP<br>(it changes every few days, or whenever the connection drops and
<br>reconnects).<br><br>>From that point on, there are lots of entries in the logs as follows:<br> chan_sip.c: Got 200 OK on REGISTER that isn't a register<br><br>So I guess what's happening is the external IP is changing but the phone
<br>doesn't know, and it's religiously sending its refresh signals every x<br>seconds to the asterisk server.<br><br>The remote extensions are all defined with nat=yes in sip.conf<br><br>Any way to fix this (short of telling the clients they need a static IP) ?
