[Freeswitch-users] SSL/SRTP VS SSL/ZRTP

[mehroz]

ZRTP worked fine before setting up SSL/TLS SIP.

Later after configuring SSL/TLS , i found zrtp not working as expected.

My phone do send zrtp-hash, and i see...
v=0
o=9999 0 0 IN IP4 192.168.15.3
s=-
c=IN IP4 192.168.15.3
t=0 0
m=audio 5072 RTP/AVP 3 8 101
a=rtpmap:3 GSM/8000
a=rtpmap:8 PCMA/8000
a=rtpmap:101 telephone-event/8000
a=extmap:1 urn:ietf:params:rtp-hdrext:csrc-audio-level
*a=zrtp-hash:1.10
d4a3ad55fce2a0b7709a64b73e55cde31756ac5a4a261e50dafcad281bf3692a
*

and then.....
/sofia_glue.c:4037 Found audio zrtp-hash; setting r_sdp_audio_zrtp_hash=1.10
d4a3ad55fce2a0b7709a64b73e55cde31756ac5a4a261e50dafcad281bf3692a/



and later in the logs i see.....
 /switch_channel.c:3100 sofia/internal/9999 at 198.84.61.52 ZRTP not negotiated
on both sides; disabling ZRTP passthru mode.
/



Can any one help me out?
