so in the phone preferences, I try to clikc "use 1 for regular voicemail: Key 1 will follow voicemail handler" but with the voicemail handler options, my only option is "none(dial voicemail number)". I'm running CM7 and I like having 1 as my voicemail quick dial. When I clicked "use 1...." and dialed, it says "ussd code running," and then it says "connection problem or invalid MMI code."
how can i fix this?
