Ringing time is an account and number level setting and its default is 35 seconds.
If you wish to change the current ringing timeout of 35s for your account or for a specific phone number, please read through our Numbers Custom Settings article.
Depending on the timeout that you have determined, Talkdesk will dial agents’ devices or If-No-Answer/IVR external numbers for this maximum amount of time before the call goes back to the queue or voicemail, depending on the account or number routing settings.
