Why can't I make outbound calls?

[ConnorThomp]

Whenever I try and make an outbound call I am greeted with the following errors in my action log.

Any ideas?

07/09/2021 00:13:36 - Call to T:Line:10000>>+4425@[Dev:sip:[email protected]] from L:22.1[Extn:2001] failed, cause: Cause: 603 Decline/INVITE from 217.10.68.151:5060

Hi @ConnorThomp,

Can you provide more information? https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

Hi @ConnorThomp,

I am running 3CX in the cloud and it is being hosted by AWS.

However, I have encountered another issue this morning, as I can no longer access my 3CX instance via the url (mydomainname.3cx.uk). It was working last night, but now it refuses to connect.

Hi @ConnorThomp,

I'd first run a nslookup to make sure that the FQDN is pointing to the correct IP.

If yes, are you able to SSH into the machine? If so, you can check if any 3CX services are not running (such as the Management Console service, nginx etc) and start it if needs be (ignore the Hotel Module).

Appears it was a service issue, I restarted the AWS instance and everything sparked back ti life.

Though I am still unable to make outbound calls, as it is producing the same error.

Hi @ConnorThomp,

The decline is coming from the provider, so I'd suggest contacting them and asking them why they're declining in this case.

I would confirm that they do, indeed, want a leading +, and not a zero (perhaps without the country code?), on national calls.

What number are you dialling, as the number in the log is +4425 - this is not a UK number - probably why it is failing

As you have already posted another thread on the same subject - https://www.3cx.com/community/threads/outbound-calls-arent-working.79314/

As you need to enter your number in E164 format - 442033933909, I would say outbound calls need to be in the same format.

Look at your outbound rules to format your outgoing number correctly - https://www.3cx.com/docs/manual/sip-trunks/.

Check your E164 settings under settings

Maybe worth a call to their tech support to resolve your issue
