changing SIP port is grayed out?

[Leon Zetekoff]

I'd like to change my SIP ports to something non-standard for extensions but leave trunks alone.
Can't seem if that can be done?

THanks leon

Yes but only on installation of the PBX:

See slide 16 here.

ugh thanks it would be nice to be able to do this post-install
