Sip settings question

We’ve been using freepbx for a long time. I think some of the settings are still default from 2008 . So I want to check if they should be changed. We are an all IP setup .
Our new hardware has 32GB ecc memory, server grade ssd’s and /proc/cpuinfo shows Intel® Xeon® CPU E3-123 .
load average: 0.02, 0.12, 0.11

so we have plenty of compute resources to spare.

item current quesiton
FreePBX Advanced Settings
SIP Channel Driver chan_sip can it be changed to ‘both’ which is the default

Conference Room App app_meetme app_confbridge is the default now. can it be safely changed?
