>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_sip/SRTP
>    Affects Versions: 11.20.0
>         Environment: Interoperability with Snom D725
>            Reporter: Joerg Sonnenberger

> When trying to forward a call from a D725 with encrypted RTP, the crypto handshake fails as the phone tries to use a zero crypto tag.
> A potential fix can be found in https://www.netbsd.org/~joerg/patch-channels_sip_sdp__crypto.c
> The same issue should apply to newer releases as well, but I can't test that easily.
