pasandev updated ASTERISK-27981:
--------------------------------

    Description: 
possible memory leak on res_fax_spandsp.c according to "memory show summary" command, mem allocated to res_fax_spandsp.c keeps growing.

I have a simple gateway setup to terminate calls from/to supplier using PJSIP Channel driver.

Customer <> Asterisk <> Supplier
