Telus landline allows me to set the number of rings before a call goes to voicemail. I wish mobility had the same feature.
I believe this should still be possible. You can set the number of seconds (not rings) before going to voicemail. See this post:
@Shane Please refer to to the thread @FuzzyLogic shared below, and let me know if the solutions mentioned works for you. You should be able to increase it to maximum of 30 seconds (6 rings) before the call gets directed to voicemail.
