Please assist,
3cx is hosted on aws, I have a SBC setup in office, SIP ALG is disabled. Firewall test on 3cx all Green. Calls on extension to extension is working. However when I try to make outbound call this error comes and no incoming calls as well. Please suggest what can I do to fix it. Been trying to fix the issues since last 4 days.
Tried disabled Put Public IP in SIP VIA Header - still same error
Tried disabling PBX deliver audio - still same error
I am using Yealink T43U Ip Phone, please note this issue is only in IP phones, When I try to make outbound call using 3cx app or web client it all works fine.
