Summary:                    large memory consumption of udptl.c module
Description: 
sizeof(struct ast_udptl) = 167592.
This structure is allocated for each SIP leg in case if t38_udptl is
enabled.
For 600 calls this gives 600 * 2 * 167592 = 200M consumed even though NONE
of these calls transfers fax at the moment.

IMO this structure should be allocated only when fax starts.
