SIP isn’t a four letter word, but for many years it might as well have been for most of us trying to use it. The results of a SIP deployment could be messy: poor voice calls, issues with phone features, and dropped connections only scratch the tip of the iceberg. Despite this our clients have often insisted they wanted to deploy SIP to save money. Along the way we have learned some valuable lessons. There is a right and a wrong way to deploy SIP, and I am sorry to say there are good and bad reasons to deploy it, too.
More and more companies are deploying UC, and most hated the process of getting there. They enjoy the end result of having a cloud-managed IP phone system; they like the flexibility of adding and removing user features on the fly, but I dare you to ask them what the deployment was like. How did the migration go from an on-premises UC solution to cloud? Was the cutover smooth as butter? Did the vendor communication make you feel butterflies and rainbows deep inside? Were the users singing your praises after the incredible training experience? Hell no!
