changing time or rings until calls sent to voicemail

[rockyfox13]

My iphone SE rings twice and then holds for awhile before sending callers to voicemail.  I can still answer while they are holding, but many people just hang up. Is there a way to change the amount of time or number of rings before it goes to voicemail?  I'd like it to ring longer before going to voicemail.

I don't know if it can be changed but I found this on Reddit from 9 months ago posted by Visible support, I have no clue if it will work. 

1. Open the Phone app

2. Type * * 6 1 * 1 0 1 * * [15, 20, 25 or #]

3. Press the call button

Within the brackets I believe is time duration in seconds. it would be **61*101**30 for a 30 second duration before going to voicemail. I also found a 7 year old Reddit post where a Visible employee replied and said the voicemail system was set to 15 seconds but was changed to 30 seconds. That was the old cloud based system that Visible was on before the current Verizon core system. If you can't get it changed maybe contact customer service and see what they say.
