ScreenOS ALG does not support Secure Real-time Transport Protocol (SRTP)



Article ID: KB29260 KB Last Updated: 27 Jun 2014Version: 1.0

This article explains why ScreenOS ALG (Application Layer Gateway) does not support the Secure Real-time Transport Protocol (SRTP).


SRTP is sometimes used to secure the traffic between the SIP phone and the SIP server.



ScreenOS ALG does not support SRTP because ScreenOS ALG cannot parse the encrypted data in the SIP payload.

Workaround: Use RTP over IPsec.
