> Asterisk crashes randomly when using chan_pjsip and Cisco 7962 phones. This is the first repeatable bug I found, the other crashes happened when the phone would attempt registration and do not happen after upgrading from 13.12 to 13.13.1. I have not tried other phone firmware versions but I can upon request. Server backtrace is attached.
> Actions to reproduce:
> -Register Cisco 7962 to chan_pjsip using TCP transport (see attached XML config files)
> -Dial an internal three digit extension, call completes correctly
> -After call try typing extension number again and Asterisk will crash and phone will reset indicating lost registration with SIP server. 
> Note: On my phone external numbers do not cause this issue
