Hi everyone, I think this post will be very useful for everyone, I have tried this on few production environments and requires some tweaking but nothing impossible, just make sure you are aware of how the call flows and how it interacts with other endpoints.
Previously the issues I have had with this configuration have been based on DTMF, oddly enough DTMF on International calls only. Fortunately the case was resolved by our provider in conjunction with few commands that are listed in this document.
This is a link from the Cisco website, but I really like this as part of my toolbox!
I think this blog has lately becoming my bookmarks place! – happy reading
