My FreePBX is running on version 13.0.197 with the Asterisk version 13.18.3.
I am looking to test drive the Zulu; however, from the FreePBX web dashboard I was told “Invalid SIP Driver for Zulu”
SIP Channel Driver must be set to both or chan_pjsip in Advanced Settings. Then restart Asterisk
This is currently set to chan_sip.
Could there be any a negative effect if I change this is to both?
Is there anything I can do ahead of time to ensure phone calls will still going through fine after the change?
