          Components: Channels/chan_pjsip
    Affects Versions: 13.1.0
         Environment: Asterisk 13.1-cert2

After setting "connected_line_method=update" in pjsip.conf the system will segfault when performing an attended transfer before the called party answers. For example:

Extension 4406 calls extension 4407.
Extension 4406 and 4407 are in conversation.
Extension 4407 presses Transfer key, enters 4408, and presses Dial.
Extension 4408 is ringing.
Extension 4407 presses Transfer key.
The system segfaults. For reference:
