Twilio call drops unexpectedly after one minute

Question

I am using Twilio studio for creating a survey, my issue is whenever the flow arrives at a 'Record' or 'Gather' widget, if the recording time exceeds one minute the call ends unexpectedly. I set 'MAX RECORDING LENGTH' to 180. I checked the call logs, for the 'Record' widget there was no warning and for the 'Gather' widget it shows the following warning:

Msg "phone_call model must have positive speechTimeout. Falling back to model numbers_and_commands with speechTimeout auto."

speechModel "phone_call"

ErrorCode "13335"

LogLevel "WARN"

Answer 1

Open a ticket with Twilio support from the Console, Submit a Ticket with 3 CallSID's less then 48 hours old demonstrating the issue.

You will want to enable Voice Trace before reproducing the issue for Twilio Support.
