Description:	Hello everyone, I am running asterisk with the version / OS described above. When I have dynamic hosts in my IAX trunk definitions. I get the error bellow this paragraph. It keeps changing the default port constantly. When port is 4569 (default) I can make calls between asterisk boxes, but when switched to 1024, calls fail and circuit is busy. I have temporary solved the issue by keeping static routes to my boxes. My bindport in both iax.conf is bound to 4569.  -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3239    -- Registered IAX2 'iaxlazaro' (AUTHENTICATED) at X.X.X.98:1024    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3210    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3250    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3243    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3246    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3212    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3215    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3113    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3234    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3230    -- Registered IAX2 'iaxlazaro' (AUTHENTICATED) at X.X.X.98:4569    -- Saved useragent "Aastra 480i/1.4.3.1001 Brcm Callctrl/1.5.1.0 MxSF/v3.2.8.45" for peer 3237    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3252    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3251    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3221    -- Registered IAX2 'iaxbrownsville' (AUTHENTICATED) at X.X.X.18:4569    -- Registered IAX2 'iaxbrownsville' (AUTHENTICATED) at X.X.X.18:1024    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3257    -- Saved useragent "Aastra 9480i/3.2.2.2088" for peer 3254    -- Saved useragent "Aastra 9480i/3.2.2.2088" for peer 3256    -- Saved useragent "Aastra 9480i/3.2.2.2112" for peer 3225 As additional information.

Thank you in advance.
Comments:	By: Joshua C. Colp (jcolp) 2013-12-01 07:14:01.019-0600 This is not a bug with Asterisk. The chan_iax2 channel driver uses the source IP address and port of the received packet. If this is displaying as 1024 then something outside of Asterisk is changing it (be it a NAT device or something else).
