---------------------------------------------------------------------- 
The attachment res_srtp.c.patch is a modified version of the workaround
mentioned in comment 0124536 compatible to asterisk-1.8-beta1.

Using Snom 370 (8.2.35) TLS + SRTP setup worked fine. Make sure to select
"SRTP Auth-tag: AES-80" in Snom RTP configuration. Selecting AES-32 failed
("res_srtp.c:306 ast_srtp_unprotect: SRTP unprotect: authentication
failure").
