I have a setup that I can’t seem to figure out how to make work. My main provider, Brighthouse, puts a gateway into my closet on its own, separate, cable connection. For the most part it runs almost perfectly. Call quality is as good or better than any other provider I’ve tested and since it uses its own cable connection, isn’t affected by our data usage. Unfortunately for our outside offices, it isn’t able to add numbers from other calling areas or caller-id’s from other carriers.
So we’ve decided to add a second provider. We are testing both Bandwidth.com and Broadvox.com but I can’t seem to find a way so that both Brighthouse and one of the new providers can work at the same time. Since Brighthouse puts a gateway in our office and we have to send all data to their servers via it as a proxy, we need to have our external IP show as our private address. That obviously doesn’t work for the other providers since those need to be set as our actual external IP.
Is there a way to set the external IP by trunk instead of at the system level? Most of my configuring is done via FreePBX but I have muddled my way through manually editing the conf files if you are specific enough.
Thanks in advance.
