3CX not calling outbound

[Joel Black]

Hi everyone!

Hoping someone may be able to help me.

I've been running 3CX Version 10 for some years (5-7) without any issues, how ever recently it's been causing issues and crashing so I installed V15.

I have a SIP Trunk with Engin in Australia and it is accepting incoming calls. All my extensions can receive and make calls internally and but cannot make outgoing calls.

I have a outbound rule set to stripe the 0 infront of the phone number (we use "0" to fail out) and in the older version this worked fine, however in the V15 our phones are getting the following error.

SIP Server/Call Manager ID: 12294
Call or Registration to 4915xxxxx@(Ln.10000@Tommirock) has failed. 203.161.160.71 replied: 403 Authentication Failure; from IP:203.161.160.71:5060

i've tried many different extensions and Land and Mobile phone numbers with no luck.

thanks in advance for any information or help

Hi @Joel Black ,

The error you are getting says "authentication failure", if the IP in the message is your providers IP then you should contact them to see why you get this message from them.
