Calls rejected.

[Anthony R]

Hi team,

We are having some issues with some outbound calls in one of our systems, we are getting the following error from time to time:

"3cx cannot reach the number you called. The number may be incorrect or temporarily unavailable."
But this has happened with actives numbers and we ended calling them using our personal cell phone. See some of the errors attached bellow:




This starting ocurring today, do you have any idea why is this happening and how can I fix it?

Thanks for your collaboration in advance.

Sincerely,
Anthony R.

Hello,

Have you reached out to your Trunk provider, as they should be able to let you know where the call is rejected. Perhaps your DID has a low reputation score and some destinations block it?

Had this before, couldnt figure out what was happened..

we had a customer who are 99% outbound calls and I had accidentally put back in some old DDIs they had previously used and they were being rejected because they were marked as spam.

This sort of question would greatly benefit from having a SIP capture handy. With the SIP capture, or at least a description of the SIP flow, anyone willing to respond and contribute would get a better picture and provide more pointed responses.

Hi team,

Thanks for your replies.

Well, you all should be right, they are new customers and we have just re assigned their DID from one provider to other, I believe the lack of a history or reputation can be trigerring some spam filters that are rejecting the calls.

We've created a SIP provider support ticket to see what we can do for this customer, thank you so much!
If there's something important that pops up I will post it and let you know.
Kind regards,
Anthony R.
