I am working with someone and they are moving their office to a new location in the next few months. They are looking to take this opportunity to modernize their phone system. So, I am working on getting myself more familiar with Elastix etc but in the meantime, we would like to put together a plan so they will know how much to budget. Here are some details: - Office with 15 employees in the main location with one at an outside office. The outside office does not HAVE to be included in this plan overall. - My estimate would be that the most external concurrent calls they would have is 7 or 8. - Currently has PRI that provides voice and data. (I think that is the correct term.) Basically, all the channels are for data traffic until needed for voice comm. Currently pay about $510 per month for this circuit with 20DID numbers So, based on that what would your plan consist of? I am looking for input from both people who have done this for their business as well as people who install systems like this for a living. My first thought was to just stick with the same kind of circuit they have now and they look into what type of card/device I would need to interface the two. This really wouldn't provide them with any cost savings per month but allows for rock solid voice communications. Another option I was looking into was to get 2 DSL lines, one for data and one for voice. Then, use someone like Vitelity to provide the majority of the DIDs etc. This plan seems to provide more cost savings but would have more potential for problems IMHO. Your input is greatly appreciated!
