Unable to register Cisco 7965 - REGISTER transaction (key exists)

Asterisk 13.9.1 Freepbx 13.0.190.7
Chan_SIP ext 5001, I can register using Cisco 7960 but when I tried the same extension using Cisco 7965, I’m getting a warning message

[2016-12-28 21:45:35] WARNING[26939] pjproject: sip_transactio Unable to register REGISTER transaction (key exists)

Firmware was download from Cisco. I also tried SIP45.9-4-2SR2-2S with the same result.
I also tried setting NAT = Never on the extension.

I appreciate if someone can verify the XML and see if I miss anything.

Thanks
