Can't connect to trunk

[CSW]

Hi!

We're currently evaluating 3CX (via a Google Cloudserver). We got three trunks, but one of them doesn't want to connect.

The current settings in Asterisk are:

Trunk name: 68485xxx

PEER Details:
username=68485xxx
type=friend
trustrpid=yes
sendrpid=yes
secret=xxxxxxxxx
qualify=yes
nat=yes
keepalive=45
insecure=port,invite
host=pbx1.belcentrale.nl
fromuser=68485xxx
fromdomain=pbx1.belcentrale.nl
dtmfmode=rfc2833
disallow=all
directmedia=no
allow=ulaw

Incoming Register String:
68485xxx:[email protected]/68485xxx

The errors we are getting:

Who can help me?

you got a 603
603 Decline The destination does not wish to participate in the call, or cannot do so, and additionally the destination knows there are no alternative destinations (such as a voicemail server) willing to accept the call .

So you need to check with your trunk provider if there's restriction from IP connecting to them.
