Avoid SRTP in BSS

1. Brekeke Product Name and Version:
SIP Server Standard 3.8.3.4
2. Java version:
1.8.0_161
3. OS type and the version:
Win7 64 bits
4. UA (phone), gateway or other hardware/software involved:
ISDN/SIP gateway
5. Your problem:
I have an user agent that is misbehaving and sometimes sending INVITEs with request for TLS/SRTP, and BSS is taking it, but the gateway doesn't work well with SRTP.
Is there a way for BSS to negotiate a call without TLS/SRTP even if the UA requests it?

SRTP is defined in SDP so it is negotiable.
It means the gateway simply ignores SDP attributes about SRTP and sends back non-SRTP SDP with 200 OK response.

For TLS, it is not negotiable generally.
Since Brekeke SIP Server can convert TLS to another transport protocol such as UDP, let you consider to have a DialPlan rule to convert TLS.
