-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I have late codec negotiation enabled and using Snom devices for encrypted calls (inernal only). When sdp of A-leg (Snom) has a=crypto I export sip_secure_media=true in my dialplan, so that B-leg (Snom) is also encrypted via srtp. That works nicely. When the B-Leg doesn't support srtp I got an "incompatible_device" error. This is also ok so far. Unfortunately this way you can't use Snom's optional srtp mechanism which consists simply of two media profiles in A-Leg's SDP (first RTP/SAVP then RTP/AVP) so the target can choose to encrypt or not. I don't know whether this is RFC conform or not nor if this makes really sense. I would like to be able to call a non encrypting ATA for checking for eaxample fax devices by simply calling them. My question is now, is there a way to tell FS sending outbound calls also with a non crypto offer within same sdp to B-Leg, so that it can choose to encrypt or not? regards helmut -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) iD8DBQFMYVJB4tZeNddg3dwRApBGAJ9d4keb5RQqMlS5sJ6jfN3VLAQkhwCeO3/x QlwcZMCW2ipsAIjV7cet2aU= =qzpR -----END PGP SIGNATURE-----
