[Asterisk-Users] Asterisk behind dynamic IP

[Tim Alder]

Warning: Virginal Post!

Hi All

I have asterisk 1.2.4 dmz'd behind an ADSL broadband router with an IP
address that can change up to several times a day (courtesy Telkom SA).  If
I manually plug the current IP into "externip" in sip.conf, SIP audio is
fine.  If I try to use "externhost" & "externrefresh" instead, the box
doesn't seem to keep up and I end up with one way audio.

What am I not aware of??

Kind regards
Tim
