Optimize and Maintain IVR system (SIP+Twilio)

Job ID: 31127877

Budget: $15 – $25 USD

Hi! We have an IVR system that is built from scratch.
SIP and Twilio are used. It's working fine for a month now
but lately, we keep encountering errors that cause the IVR to be in downtime.
We need help from an expert to fix this error and make sure it won't happen again.
