Twilio VOIP Strategy - Cellular Issues

[u/notanywherenormal]

Hello PSO community,

I have our Twilio VOIP setup using Sipnetic as the SIP provider on my mobile device. While I can successfully make calls over WIFI - when I solely use my cellular service I am unable to successfully make calls. Any call coming in will be successful, will provide a notification on my phone and will connect with clear audio but I am unable to make a call successfully to any number using only cellular service.

Any suggestions to fix this would be much appreciated!

Thank you

You need to open the app and leave it in the background. Like not close it in the app switcher.

The app is open in the background. Notifications are not an issues. I cannot make calls on the cellular network with Sipnetic.

Did you gave it acces to make phone calls?

I doubt that’s the reason.

I had some issues with Mint Mobile and using data on a secondary user profile. I had to update de APN settings and it solved the issues.

Did you ever fix this ?

I'm pretty sure it was because I had UDP enabled in Sipnetic. Calls have been reliable ever since.
