Problem with Outbound Calls

[RajatB]

Hi Team,

I am having issues with Outbound calls. I have a 3cx system hosted in AWS, the inbound call works perfectly fine but whenever I try to make a call outside my extension i.e. to a real number rather than an extension, it sometimes says Forbidden, not found, or temporary error. Could someone help me with this, please?
I have checked the necessary settings in AWS and it seems to be fine. I have also implemented a few Outbound rules to strip and prepend the number following the 3cx guide but no luck.
The number I've provisioned is a US toll-free number. I am trying to make a call to US local number and few international calls but nothing seems to be working. Can someone tell me if I am missing something here, please??

For international call I've added + as a prefix and prepend as 011
For local call I've just added a number, stripped it and prepend it as +1

Any help will be much appreciated.

Make sure you are using a preferred or supported voip provider. You dont mention the provider you are using.

The 3CX Activity Log will show if the call is indeed reaching your provider, and if they are sending a rejection reply.
It could be one of two things...the dialed number is in an incorrect format, or, the caller ID you are sending is not supported, and causes the call to be rejected.

Thanks for your reply Nick. I think Voip side is fine as I am receiving calls,its the outbound that is not working.
I am using Amazon Chime as a Voip provider.

Thanks, Leejor,
I just did a test capture for the activity log and it says "Target endpoint for the connection can't be built"
Not sure what this is?

Did you check
• Outbound rules match the dialed number ? (not only prefix but also which ext / groups are configured for the outbound rule)
• Allowed country codes ? (3CX MC > Security)
• Under Activity log is there any error message from Provider's side ?

Your outbound rules must match the number you are dialing, it doesn't sound as if that is currently the case.

Then the rules must pass on the number in a format that your provider is looking for...
