IOS won't receive phone calls

[ardeshir-33033]

I have followed the path for the package instruction for Android and in Android I get calls and everything is fine. but in IOS instruction there is nothing special on the documentation and my app won't receive calls. But twill voice instance says that the phone is registered though. can you hint me where the problem might be?

iOS does not require any special setup requirements by the package itself other than mic access & push notification support. In debugging why iOS does not receive calls, there can be several issues.

Device checklist:

• Do you have push notification access?
• Did you successfully register your device with Twilio Voice?
• Is the Twilio AuthToken expired/invalid?
• Are you calling / receiving calls to/from the correct client Id
• (iOS specific) Are you using the correct APNS credentials when generating your token? (Sandbox/Production, see iOS Push Credentials)

Backend checklist:

• Did you generate a voice grant token?
• Did you correctly assign the client Id?
• Does Twilio Logs report an error delivering call (see Twilio error logs)

This is not extensive, but a start.

@ardeshir-33033 (updated, check your credentials token, might be the problem)

Hi @ardeshir-33033, any luck?

Hi @cybex-dev Sorry for the late response, yes great checklist by the way, the problem were in the IOS push credentials Sandbox and production mode.

Wonderful, I'll close up the issue.

I'll make an FAQ section too to address these types of issues, thanks for the (suggestion).
