    Sangoma
    Digium Asterisk is well suited for a city government as a communications solution for internal and external use. Other options like PBX are more expensive and hard to escalate. VoIP makes it easier to use the communications infrastructure instead that already exists rather than having to wire every phone when the solution is a digital or analog phone. In my city, government offices are not in the same place, which makes it harder to communicate everything together.

    Cons
    Ring4
    • I've sometimes seen text messages being sent in double.

    Sangoma
    • Transferring to a Voicemail is particularly hard to do, and calls tend to drop when transferring.
    • I would like a different interface; the current one feels clumsy
    • Over the weekend, it logs you out, and you have to remember your password or reset it to gain access.

    I have asked in the not so recent past about having my phone updated with my saved Digium "favorites" list but it doesn't seem that this is possible

    Ring4 had everything we need in a business phone line in a more simple format and less expensive.

    Recently I've been using Vonage Business, and while it is far more expensive and a lot less configurable than Digium, the mobility is essential for my new role. Digium is ideal for a business with both a very technical staff and a user base that is not remote. Digium was selected due to price and ability to create custom applications.
