No voicepath on 1230 phones over BCM50 R6 but 200X & 11X0 does

[sroggero]

We're IP Phones on a BCM50 R6 with NAT Traversal activates, we're using i2002 & i2004 without any problems remotely... when we try with any 1230 & 1220 they can register but no RTP is going thru, no dial tone on INTERCOM or lines... no voice at all.

I tried to open up all the possible port but I can't figure out what the problem could be, is there a difference on RTP 200X vs 12XX or is there anything to program on the BCM....

I made the same setup on a BCM450 R6 and I got no problem, I forwarded port 1 to 65,000 and it worked immediately but not on this BCM50...

All port have been forwarded... 1 to 65000 to BCM

1230 are still getting no voice at all
200X are working

What could be my problem...

Please help
