Hi all,

i try to deactivate SRTP in asterisk 11.

In sip.conf:

tlsenable=no
encryption=no
transport=udp
srtpcapable=no


but when I try to make a call comes following message:
[May 9 15:19:03] DEBUG[24745][C-00000086]: sip/sdp_crypto.c:285 sdp_crypto_process: Accepting crypto tag 1
[May 9 15:19:03] DEBUG[24745][C-00000086]: sip/sdp_crypto.c:310 sdp_crypto_offer: Crypto line: a=crypto:1 AES_CM_128_HMAC_SHA1_32 inline:SYZjzhCe4mg0M18YvnkqtrH9lD3+/LQb3PuMoOI0
[May 9 15:19:03] WARNING[24745][C-00000086]: chan_sip.c:10526 process_sdp: We are requesting SRTP for audio, but they responded
without it!
(call from a snom)

I understand this message so that asterisk continue attempts to use
SRTP.

I could disable SRTP on the SNOM, but I want to have it disabled by
default. Because i have many enddevices.

Greetings
Dominique

Either you do not compile the srtp module into the Asterisk package or you disable RTP
encryption on a phone by phone basis.
