I'm testing a scenario where 3cx is in the cloud and all extensions are remote. The problem seems to be that if you have more than 1 extension at the same location, only 1 of the extensions is guaranteed to be able to receive inbound calls, and the rest will not likely ring.
I was playing around with this at home yesterday behind a linksys (ddwrt flashed) router. I had 2 spa504g phones and 1 3cx softphone using tunnel. For only a SHORT period of time, I was able to call in from my cell phone and all 3 extensions would ring. I tried several times and was able to answer the call on each extension with 2 way audio.... but eventually it came down to only one extension ringing and being able to answer the call.
In this same setup, all the extensions can make calls no problem with 2 way audio. It's just the inbound with multiple extensions on the same network that causes the problems. I've tried both at home and at the office and experience the same problem. Whichever phone registers first on port 5060 will accept the inbound calls but any other registrations might ring, but you wont actually be able to answer the call.
How can I overcome this?
[SOLUTION]
CHANGE sip port on individual phone
DISCLAIMER - do not read the rest of my posts unless you want to get extremely confused!!!!
all of the crazy problems I was having were a result of me realizing the phones could not provision remotely, and the new extensions I had attempted to reconfigured were still configured to connect on a lan, so I hadn't configured advanced nat options per this article http://www.3cx.com/blog/voip-howto/remote-extensions/
