After a change of the WAN IP address has caused numerous problems with some phones and system in general.

1. can no longer make calls to extensions
2. Can not transfer calls of course
3. Codec issues on some phones can not hear voice from one end
4. Auto config seems to be taking the old IP address still..

Have checked RTP settings but cant see anything that can be done.
Also have tried unchecking force self codecs but to no avail.

So before I go and reset the Quadro 2x2 any other things I should look at??
