2x scenario below between CM <SIP TRUNK> CME, scenario 1 is working, but scenario 2 can it be supported?
scenario 1. normal sip trunk (with SRTP allow is working)
scenario 2. between CM and CME (secure sip trunk profile not working on CM to CME) <- does CME support secure sip profile to CM?
--------------- scenario1.
on CM when i add SIP trunk (using non-secure sip trunk profile) and check on SRTP to allow, SRTP traffic is working between CM and CME
my CME configuration as follow
!
dial-peer voice 1 voip
destination-pattern 5...
session protocol sipv2
session target ipv4:10.1.1.1
dtmf-relay rtp-nte
srtp
!
--------------- scenario2.
on CM when i add SIP trunk (USING SECURE SIP TRUNK PROFILE) and check on SRTP to allow, the call cannot be establish to CME
question A. on CME what do i need to configure to make it work to establish secure SIP trunk encrypted TLS with CM?
does CME support encrypted TLS SIP trunk with CM?
question B. or is SIP trunk security profile for encrypted TLS signaling is just for between CM to CM?
and not for CM to CME?
anyone has answer or solution to question A and B?
