I recently sold a BCM50 to a re-seller with IP Client licenses and NAT Traversal. Their customer could get a 2004 IP phone to register remotely, but there was no audio. I then had the re-seller try to connect to my own BCM50 with a 2004. Same thing, the phone would register fine, but no audio. I had used 2002 IP phones remotely on my own system several times, so I was stumped as to what had changed. All the correct ports were forwarded (7000-7002, and 30000-30099) to my BCM50.
Another customer of mine then called who has recently installed several BCM50's with IP phones and NAT Traversal. So I related my problem to him. He verified that all my router settings were correct. He then mentioned that he quit using the older 2000 series IP phones due to similar problems I was experiencing. He then connected to my system with a 1230 IP phone and it worked perfectly. I then called back the re-seller and asked him to connect to my BCM50 with another type IP phone. He used an 1120E IP phone and it worked perfectly.
So if you experience one-way or no audio with remote 2000 series IP phones, try another IP phone before diving into BCM IP settings or router port settings. It might save you much grief and head banging.![[banghead]](/data/assets/smilies/banghead.gif "[banghead] [banghead]")
The 2000 series are getting long in the tooth and starting to fail. I still have an old 2002 IP phone that works fine, but it looks like a matter of time before it kicks the bucket.
I hope this helps.
