Issues with Twilio trunk set up.

[JR99]

Hi,

I set up a Twilio trunk vis the auto method on the admin portal. The issue I am having is when a call is received it maxes out the Mac SC I have, and the call fails. Twilio says that the PBX does not send back that it received the call, so if I try to ring a call on it, it could ring 100 SCs on it.

texts work ok.

I looked through the set up a few times and didn't see anything that would be helpful with this issue, also didn't see anyone that had this same issue on the forums.

Twilio claims it's no issue with them, but the PBX itself.

What can I look at to solve this? I don't have any firewall restrictions that would block outbound. I have two other trunks set up without any issues.

Hello @JR99

Is the issue only with inbound calls or does it also happen with outbound? When the call arrives do you see it ringing in the PBX? If so can it be answered?
Did you add your number in the +E164 number format? And lastly does the firewall checker pass if you run it?

Hi,

Yes the call arrives, and you will see it ringing and then it will keep stacking up multiple calls waiting from the same number. when you try to answer it. on inbound calls even if the call is answered it still rings the number and will leave a bunch of missed calls and voicemails.

it seems that the call will connect, although doesn't seem like voice is not getting transmitted over it, and the call is ended on (my cell) number it doesn't end the call on the pbx.

yes it is in +E164 format, and passes firewall check.


I haven't had any of these issues with my flowroute and bandwidth trunks. I got this trunk for a bulk sms campaign, and want to be able to receive texts and calls if a customer called on it.

Twilio says they never receive the signal the call is received.

I will send you a pm so we can take a look at a few things with more detail.
