“Extend our current PSTN solution without causing an internal landslide”.
That’s how you could briefly describe the question UNMS presented to us. A nice challenge and a great example of how we configured a PSTN extension in a cost-effective and user-friendly way. Read the entire story!”
UNMS aimed to extend their current classic PSTN solution (Public Switched Telephone Network), so people would be able to work place, time, and device-independent. The customer already used Skype and Teams for internal communications.
The biggest challenge was that they didn’t want a big bang migration and still desired to keep using the current classic PSTN environment. They also wanted to keep the internal communication between Teams and systems as smooth as possible, with ‘short numbers,…’. Whatever system the client used, they should be able to call a colleague seamlessly.
We suggested to add voice telephony to the Teams tenant, so they could realize their goals in a cost-effective and user-friendly way. As the clients were already familiar with Teams, the user adoption would be much less. We created a direct routing gateway to extend the existing PSTN solution to Teams. By means of this, the customer could still use the old telephony where they prefer, and easily move to Teams voice if desired.
In agreement with the customer, we opted for a phased solution. We worked according to the following process:
Gather the business needs and customer requests.
Deliver a project plan with timelines and regular customer reviews.
