hi,
is it possible to force a selected crypto for SRTP as i cant
seem to find a way to force a crypto to the user such that is
phone uses that for media, secondly i see zoiper sends the below
in SDP
a=crypto:5 AES_256_CM_HMAC_SHA1_80
inline:854nJNIKSyhr0sJs+Ol+Qv2eSqC2gnydK8iVHUAXb4Xx7oW8iMM2jVi7R9xV6A==
a=crypto:6 AES_256_CM_HMAC_SHA1_32
inline:854nJNIKSyhr0sJs+Ol+Qv2eSqC2gnydK8iVHUAXb4Xx7oW8iMM2jVi7R9xV6A==
a=crypto:3 AES_192_CM_HMAC_SHA1_80
inline:854nJNIKSyhr0sJs+Ol+Qv2eSqC2gnydK8iVHUAXb4Xx7oW8iMM=
a=crypto:4 AES_192_CM_HMAC_SHA1_32
inline:854nJNIKSyhr0sJs+Ol+Qv2eSqC2gnydK8iVHUAXb4Xx7oW8iMM=
a=crypto:1 AES_CM_128_HMAC_SHA1_80
inline:854nJNIKSyhr0sJs+Ol+Qv2eSqC2gnydK8iVHUAX
a=crypto:2 AES_CM_128_HMAC_SHA1_32
inline:854nJNIKSyhr0sJs+Ol+Qv2eSqC2gnydK8iVHUAX
where as FS always uses the below only
switch_core_media.c:1484 Found suite AES_CM_128_HMAC_SHA1_80
and also i noticed FS and zoiper have some variations in crypto
names such as
switch_core_media.c:1479 looking for crypto suite
[AES_CM_192_HMAC_SHA1_32] in [4 AES_192_CM_HMAC_SHA1_32
and this never matches and never used at all (notice the
placement of CM_192 in FS whereas zoiper has 192_CM)
