    Pretty new to PBX and have tried different types, so far VitalPBX is my favorite.
    I am using Vitelity for my outbound and inbound calls. Right now my outbound calls work perfectly fine; however, my inbound calls seem to be having some issues.

    The error that I get is this: "Failed to authenticate device "xxxxxx8022" <sip:xxxxxx8022@xx.xx.xx.36>;tag=as01cf2674"
    With this right below it in my fail2ban logs.
    es_security_log.c: SecurityEvent="InvalidPassword",EventTV="2018-07-15T14:12:31.981-0400",Severity="Error",Service="SIP",EventVersion="2",AccountID="xxxxxx5064",SessionID="0x7f98b03fbe40",LocalAddress="IPV4/UDP/Vitalpbx's Public IP/5060",RemoteAddress="IPV4/UDP/xx.xx.xx.90/5060",Challenge="",ReceivedChallenge="",ReceivedHash=""

    I get this error in my Full Logs without SIP debug enabled:

    The weird thing about this is that if I set the “Allow Guest” to “Yes” in the “Sip Settings->Security” then inbound calls work fine.
    Is it OK to leave this setting enabled? Are there any vulnerabilities that can be exploited from this?

    What VoIP provider are you using?

    What are the configurations provided by your VoIP Provider?

    By now leave the  setting “allow guest” enabled. When this option is enabled, all unauthenticated calls go through inbound routes.

    This does not impose a security risk does it?

    No, is not insecure. this setting determines if anonymous callers are permitted to place calls to Asterisk. all the anonymous calls will go through the inbound routes.

    Ah ok. I’ll leave it enabled. I added OpenCNAM to the system which gets the customer’s name of the number perfectly fine.

    I have also noticed that Vitelity is complete trash and should no longer be used.
    They are down about 60% of the time and hardly ever worked for our PBX systems. I tested Telnyx with a free $20 promo code and the system works 100x better and I don’t have to enable Allow Guest option.

    I did, which is why I tested them. I was also able find a $20 promo code to test it which they also offered me a free local phone number which worked amazingly.
    No longer have to disabled any of my firewalls, Intrusion Detection or any other option that would impose a security risk. The funny thing is that it works without any advanced setting or options.
    Also loved the fact that they let you use their API for their services.
