I have error in twilio, says "VoIP notifications the certificate subject must end with ".voip" and the device token app bundle ends with ".voip".
when I check the similar questions found that solution is to change the
" solution was BundleID+.voip"
I tried to create a bundleId ending with ".voip" in developer.apple, though id is unique but failed to create. whenever i add .voip it does not allow me to create.
Can some me tell me how to apply the above solution.
how, where, and what i have to do to apply the solution.
Actually, you don't have to create new ID. Instead ask your backend team to push Voip notification to APNS server with header field:
apns-topic: "com.company.app.voip"
Where com.company.app is the registed bundle ID.
Maybe you can use below tool to test push notifications.

In pushfy, select push type as "voip" and App ID BundleID+".voip"
