pshultan: yeah, I had to add that line because one phone I tested (may have
been a grandstream?) if I send  only a SRTP request, would respond with
regular RTP only which we would happily accept.  We definitely shouldn't
accept responses that don't match what we send.  Would doing something like
this work for you?

 		} else if (!strncasecmp(a, "crypto:", (size_t) 7)) {
 			process_crypto(p, a);
+			secure_audio = 1;
+			if (!p->novideo) {
+				secure_video = 1;
+			}
 			continue;
 		} else if (!strncasecmp(a, "key-mgmt:mikey ", (size_t) 15)) {
 			ast_log(LOG_NOTICE, "Asterisk currently does not support MIKEY key
negotiation\n");
