I've been toying with Peers a little for an ongoing project that I have, but for this project I need to have both hold and transfer functionality. I'm by no means a Java expert, much less a SIP one, but I can find my way.
Could you please tell me how could I implement than functionality?
On the other topic, how do I create an applet? I see that Peers is somehow prepared for that, but I haven't found the way.
Thanks in advance! By the way, Peers is awesome!

I think you should add a new MethodHandler called ReferHandler. This new
method handler would have a preProcessRefer method that would populate
headers as expected before sending this request to the transferee.
Transfer feature can be implemented multiple ways in sip (you have blind
transfer, supervised transfer, etc). The simplest one is using refer /
notify methods, you probably read call flows about this method. This
feature can be complex.
for on hold feature, use an invite with special SDP attribute to mute sound
in RTP session.
someone already implemented a patch a long time ago, here is his mail:
Dear Yohann,
First of all, I would like to say thank you for your hard work in the Peers
project!
We have been developing a comlex SoftPhone application for a year or so
using JAIN-SIP, but it had flaws we couldn't understand. We decided a week
ago to trash the current SIP engine and switch it with yours. The
application is much more reliable and professional this way, but there were
some features missing (call transfer and hold-unhold function).
I have created a "patch" to implement these functions. Although I'm a
newbie in the SIP world I've nearly managed to do this. Blind transfer is
working as expected, but the re-invite is kind of strange: There's an
Asterisk server on the other side and sometimes it just responds a wrong
attribute in the SDP body as if there wasn't any request to change the
transfer direction (sendonly, sendrecv, inactive). Maybe you could help me
with this matter and hopefully you could use my code for the project as
well.
Please find the JAVA files attached in a TAR.GZ compressed file.
InviteHandler required some external code, because I couldn't find out
another way to check if it's an invite is a normal invite or a re-invite. I
hope I didn't forget any unnecessary code or Hungarian comment in it :).
Hold feature is easy to implement (you should start with this one. You just
have to look for attributes sendonly or recvonly in SDP and avoid the setup
of the corresponding objects to send or receive media (incomingRtpReader or
captureRtpSender in MediaManager).
On the other topic, how do I create an applet? I see that Peers is somehow
prepared for that, but I haven't found the way.
take a look at peers-js or peers-jws in peers source code, you can even
download a zip file containing a full example here:
Ignore - 3 seconds after I posted this the lightbulb went on inside my head. This is still referring to the 0.4.3 branch.

Johann and Arturo, I want to start with congratualting both of you with a fantastic job. I am looking at peers to create a SIP integration and looks like that will be a breeze with this lib.
One question: I noticed that Arturo's patch references net.sourceforge.peers.media.SoundManager
I don't see that class in the master branch. Is that 'just' a rename of the AbstractSoundManager or is that class missing in the patch?
Kind Regards,
Erwin

There is now a an abstract class on top of sound manager which is in a
dedicated maven module called peers-javaxsound.
In this module, you will find a JavaxSoundManager which corresponds to the
former SoundManager class.

here is a mix of the answers to the same question (on hold and transfer)
