Hi,
Is there a way in Ser to stablish a preferred order of codecs to be used by the phones?
Thanks,
Ricardo.
Hi,
No i dont think so, because SER has nothing to do with audio/video streaming whatsoever. Besides, this functionality should be attributed rather to clients than servers.

For what I've searched about, I also think Ser isn't capable of that, however, since I pretend to use Ser as a SIP router in the campus where I'm deploying this VoIP infrastructure, that functionality should be attributed to SIP server, so I can force terminals to use less bandwidth consuming codecs, because bandwidth may be some big issue when we talk about tens and hundreds of calls simultaneously! If is there any way to do it with Ser, please let me know.
Thanks,
Ricardo.

it's true, but we can make something like this:
for example: prefered codec should be "8"
subst(/^m=audio(.*)RTP/AVP(.*) 8/m=audio\1RTP/AVP 8\2/i);

What if SIP client on the other end does not support that codec? Of course, I understand that u and a-law are mandatory for every SIP client, but let's pretend that some clients just support 1 or maximum 2 codes. This substituting stuff is like playing with fire :P

they are not mandatory. they are usually supported, but not mandatory. Think about an IMS phone, which uses SIP and supports only AMR and GSM codec.

in this case subst will not works, because we are looking at " 8" payload. anyway he can at first make a search and after it make a replace (subst) :-)
Andrey.
subst(/^m=audio(.*)RTP/AVP(.*) 8/m=audio\1RTP/AVP 8\2/i);
^^^^
Wbr,
i agree with the "search first" part :)

Hi guys,
I dont think subst would do anyways. because you need to recalculate the content-length.
Ser doesBnt (as far as I know) recount content length automaticly. you need to use some function wich is not exported to the config.

As long as you are NOT adding any new entries into SDP content, but just arranging them in preferred order, I dont think recalculating content length is strictly necessary.

of course you don't need to do it, because you just change a position in the codec's string and the content-length will be the same.
Wbr,
Content-Length is recalculated when you modify the body.
