Indeed, 3CX replies with 407. However 401 as reply by 3CX is expected and requested in this case. Ericsson softswitch that tries to register on the 3CX accepts only a 401 as a reply.
Hello,
Is it possible to let the 3CX reply with 401 instead of 407 after the first register attempt from a UA?
The UA is an Ericsson SIP-gateway that only accepts 401 as reply.
Thanks in advance.
