IIRC I used to enable this option when talking to some Ericsson SBC.  It
solved a problem concerning an on-hold scenario where the sess-version
wasn't getting incremented (by the Ericsson) even though SDP changed.
Asterisk would igore the re-INVITE without ignoresdpversion.

Today I use PJSIP with that SBC and I totally forgot this setting till
now, either the Ericsson was fixed/replaced or PJSIP handles the
scenario differently.
