Opensips-cli mi command fails if response json has binary in it

[artkos]

command:
opensips-cli -x mi dlg_list

result:
ERROR: command 'dlg_list' returned: Error with connection: 'utf-8' codec can't decode byte 0x80 in position 3374: invalid start byte. Is OpenSIPS running?

position 3374 points to response json, which has something like this:

Content-Type: application/ISUP;base=itu-t92+;version=itu-t92+\r\nContent-Length: 45\r\nContent-Disposition: signal;handling=required\r\nCONTENT-TRANSFER-ENCODING: binary\r\n\r\n\u0001\u0010 .\n

position 3374 is end of \u0010

dlg_list commands works fine if all the calls doesnt have isup content.

Also opensips-cp dialog module have same problem, if there is isup content it wont show any call dialogs

Maybe problem is in dlg_list command? caller_sdp field has whole body instead only sdp content.
