Hey guys,
Sorry for the noise!
I am looking to use voicemail_ivr so I can ensure my own phrases are played and I can avoid giving the user options to record just one voicemail message (as they have the option to upload a file from our portal too).
You can do all this with regular voicemail app by modifying the phrases involved and options I think. No need to do your own completely. Take a look at the phrase configs used for voicemail and voicemail config file and let us know where it might be an issue.
