One may find VoIP a bit troublesome because using it requires a user to sign up to the service and in order to share the experience of using it with friends and family, one has to sort of market the service or maybe put in some effort to get them on board. That is not all; using VoIP across different services may also be an up-hill task but Bolt intends to make life on VoIP easier and maybe something to look more forward to.
