SPA303 & SPA502G NAT Mapping Enable & STUN problem using firmware 7.4.6

[cesterlizi]

Hi

I am testing  Firmware 7.4.6 for SPA303 & SPA502G and I found a problem if I enable "SIP->STUN Server" & "EXT->NAT Mapping Enable".  The phone does not work properly when an incoming call is received.

Example:

1002 calls 1001, 1001 automatically calls 1002

-Video -> http://www.youtube.com/watch?v=32ngud54MCU

-SIP Capture attached

192.168.1.71 1001

192.168.1.73 SIP B2BUA

192.168.1.90 1002

201.254.100.204 gateway, since stun is enable = SPA using account 1001

- Attached: sip flow where we can see that a new call is generated from the other phone

We have more than 1000 SPA922  and SPA942 working OK with this configuration with firmware 5.2.8 and 6.1.5a. I've also tested SPA502G with firmware 7.4.4 and is working fine

It's a bug or configuration issue ?
