It would be quite prudent to speak to FlowRoute Support about #1, as well. We have several hundred customers who use FR and the transition to their new PoPs has been nightmarish, to say the least. FlowRoute Support has changed up their “preferred” configuration no less than 3 times in as many weeks in an attempt to get everyone on the new PoPs. We’ve even seen FR Support setup completely different trunk configs on different FreePBX systems ON THE SAME FR ACCOUNT…which means they have been doing a lot of custom individual setups on THEIR end to work around their botched deployment of these new PoPs. It didn’t help that they decided it would be great for customer satisfaction to give folks 2 weeks notice that they were killing the original termination URI…without even ensuring that their paying customers were transitioned over. I guess they didn’t take into account that some of their customers have DOZENS of systems to migrate and that some of them operate 24/7/365 and have to very carefully schedule their maintenance/downtime (and, well, Pandemic, staff shortages, economic downturn, etc might get in the way of a speedy transition)…or they just don’t care. Based on the attitude most people seem to be getting from FR Support, it seems to be the latter. That said, contacting them is the only sure-fire way to ensure that what you are configuring is matching their latest attempts and [possibly undocumented] changes.
Enabling Force Answer may help #1, but we saw this same symptom on a few others and they did have Force Answer already enabled. It took a call to FR support to sort out the root cause.
In other words, the documentation you used to setup the new PoPs could be wildly different from the current reality on their end, even if they last updated the docs a just couple days ago. Talk to FlowRoute Support. In just about every instance that a customer has reached out, FR has gotten them sorted out…one way or a-dozen.
