Questions on PSTN Calling - PSTN breakouts map
Hi Experts, One of our customer has users in different sites (USA, UK, Ireland, Germany) and many users hosted on UK tenant who are frequently travels to USA. In this case if they make any PSTN Calls to UK users from USA it gets routed based on the USA licenses that they've got assigned. Assumes that the calls hits UK datacenter first and then routed to USA datacenter and reaches the destination which might case quality issues. Questions: 1. Is there a way of assigning the USA licenses (Dial plans) for the users hosted on United Kingdom Tenant 2. As an alternate option, do we need to create tenant in respective other sites (USA, Germany, Ireland) and host the respective users there to ease PSTN Calling traffic much faster and smoother? 3. Is there any Office 365 PSTN Breakouts global map (Like Office 365 Datacenter map) available online? 4. As a final option can we choose Express route to make PSTN Calling traffic faster because it can route the traffic to dedicated channel? (Customer is already aware of the winroom and Network Assessment process to choose Express route) Any pointers would be of great help. Many thanks in advance.
