Systems hosted on Google Cloud and twilio trunks.

[dseevers]

I am really needing some help here. I have several systems that are hosted on Google clound and I use twilio trunks for all of them. Starting the first of the week I have been having terrible issues with lag and delay on ringing on incoming calls only. I have stopped and restarted the systems and I have several customer not happy and am not able to narrow down the issue.

Thought I would add that I installed Callcentric sip trunks on these systems to test them out and they work just like they are suppose to. I attached pcap log dump of a call that took about 20 seconds to ring the phone and then came in as a double call, on twilio.

Sounds like you should reach out to Twilio for support since the problem is exhibited with the trunks and not CallCentric.

I did reach out to them. The pcap looks just fine on their side and if I forward the twilio number to my cell phone or a pots line it works fine. But once I bring it into the 3cx the delay starts and it sounds terrible.

What is your ping time to the two SIP trunks?
Sounds like you have a bad connection to the carrier, you will need to do a packet capture and check for packet loss and jitter. Have the carrier do a capture as well and play the call in wireshark.
