Jingle doesn't work

"Call" button is inactive and at startup there is a message in console:

PortAudio error at Unable to open streams: Illegal error number

Hi,

did you downloaded the coccinella binary from the coccinella website, or did you installed a ubuntu package?

do you actually have sound at all with the client?

I updated from OpenSUSE 11.1 to OpenSUSE 11.3 recently (x86_64), and I also see some problems:

without jackd running:

The sound problem still seems to be unrelated. I had to recompile snack, and my sound started to work again afterwards.

Still I get the following error messages on the console and also later...:

I added the echo bot to my roster, but it did not authenticated me to be used.

I tested with coccinella directly connected to the asterisk as a IAX2 client, and called my mobile phone. That was working well.

After again looking at it, I think the problem is that XEP-167 is not implemented in coccinella, which is Jingle Audio via RTP, and maybe some others are missing ;).
Coccinella uses IAX for audio communication, and not RTP.

someone volunteers to implement that? ;)

Sander, any other thoughts about this one? If not, I'd mark this one as a whishlist item with regard to importance.

I found this mail, with attached code here:http://groups.google.com/group/comp.lang.tcl/browse_thread/thread/190ce56039c7cfc7

so rtp in general shouldn't be too complicated ;)

I don't know of any general solution - it is fairly easy to
play a G711 PCM stream of RTP data using snack.

However, if you are using different CODECs then it will not
be so easy.

Here is a cut down example version of some very quickly
hacked together test code. ALSO this code is written for testing
with a multicast address - you would have to modify the code to use
a normal / unicast address.

You need both tcludp and the snack tool kit to use the code that follows.
