hi,

why do I need support of the sip server to run SRTP?
the asterisk doesn't just relay the rtp packets?
can it be configured to just relay rtp packets?

thanks

Not at the moment. Yu'll need to wait untill SRTP is fully implemented
in Asterisk: https://issues.asterisk.org/view.php?id=5413

hi,

thanks for the replay,

again, why does I need implementation of srtp in the server side? don't I do
srtp agaist the peer I am taking to? or the srtp is agaist the server?

can you please explain us more detail:
why do you say that you need SRTP?
i'm working with asterisk without srtp and have no problems. What wrong with
your application? Just use the default settings of pjsip - and it will be
work with RTP. Don't understand your question, realy :)
For example: i have a server(and proxy server too) and client based on pjsip
library, in all of it i've done SRTP support optional, so when i connect to
the asterisk then i disable SRTP in my aplication's settings, that's all
folks ;)

Best regards

Heh, i know what is SRTP :) I'm using it when it needs.
But - i don't understand your question:

why does I need implementation of srtp in the server side?

i don't know why do you need it, because i haven't any information about
your needings.
As i said - if i need then i use SRTP, if it isn't possible (with asterisk)

  • then i use RTP. I don't see any problems with it. Explain me more please
    ;)

cheers

I think what the OP meant is that SRTP is end to end and the RTP-Proxy
application (asterisk in this case) must just resort to simply relaying
it to the other end without participating in actual payload processing
if it doesn't support SRTP.  I think this is off topic in this list
though and I am not familiar with asterisk to give any significant
opinion on the matter.  I am sure you will get your answer in the
asterisk list if you mailed there.

Not with Asterisk. Asterisk is a PBX which decodes RTP and transform it
into the internal format.

In some cases (direct-bridging in chan_sip, or canreinvite=yes) you
might have luck as then ASterisk acts just as relay or media will be
"reinvited" to be directly end-to-end.
