VVX D60 Codec not renegotiating

I have a VVX D60 paired properly to shared line on a VVX410. I'm able to extension dial internally to VVX500 with g722, but If I dial a PSTN number in this case my cell phone. It drops the call after receiving a g729 request. If I switch the VVX410 codec priority to g729AB, I am able to call my cell phone and works. But if I then call my internal extension it will drop the call like it did earlier with the cell phone. So it seem like the D60 is only using the first codec on the priority list and not renegotiating the codecs.


If there a fix for this? tired firmwares 5.4.3 and 5.5.0 UCS.


Thanks for your assistnace.
