Yes, I would like to have this too.

I doubt this will be added - sipdroid seems to be associated with pbxes.org and 
they offer call recording is a paid option. However, it is open source, so I 
might add this at some point.

I took a look at the code. It seems like it will be reasonably simple to do. 
Here's what my 'final version' will hopefully look like:

1. An extra preference toggle: 'Record all calls'
2. If set, all calls will be recorded to /sdcard/Ripdroid/<time and date>.mp3
3. Incoming/outgoing will be in the left and right channels of the mp3.

So far I have it successfully recording the incoming part to a raw audio file. 
I've attached an example.

Ok, I got it to work. Currently it does this:

1. Record incoming audio for each call to /sdcard/<time and date>_in.wav
2. Record outgoing audio for each call to /sdcard/<time and date>_out.wav

Caveats:

1. Poor error handling. If it can't write to the file nothing happens. It also 
blindly overwrites the file if it already exists (unlikely, unless you make two 
calls within a second).
2. Wav not MP3 so expect large files (it will be a constant 0.92 MB/minute).
3. Audio may get out of sync if there is packet loss or you are on hold or 
other stuff.
4. Assumes 8 kHz sampling rate. If this changes, you'll still get the audio but 
it will be chipmunk-esque.
5. I still need to change the package name before I release it.

@tdhutt: I think you don't have to fork it to have this implemented. Just try 
to do a diff between trunk and our call recording modified version and post it. 
I'm sure it will be merged in.

Yes, sure!

Ah cool, I will clean up the code as much as possible and add more preferences 
to control things. :-)

Patch attached.

Notes:

1. Both halves of calls are now recorded to the same wav, but it is done in a 
seek()-heavy way. Not sure if that is very efficient.
2. I added some preferences, but I didn't know a good way to connect them to 
the code (which is in org.sipdroid.media) so they don't do anything yet.
3. Calls are saved to /sdcard/Sipdroid_Recordings/
4. Max call length: 18 hours. :-)
5. Some non-changes crept into the diff, e.g. I have to edit the Application.mk 
to get it to build for some reason.
6. No error message reporting. Sorry I don't know your code well enough!
7. Packet loss will probably cause the incoming/outgoing audio to go out of 
sync.

Pre-built APK here:

NB, as before the settings aren't connected to anything. This is based on SVN 
from a week ago.

Using tdhutt's apk right now, hope this feature is implemented in the official 
version soon.

heya,

Any word for when this might be included in a future release of Sipdroid? =)

Cheers,

I'm using MX Skype Recorder and you may also want to try it
http://skyperec.com 
as it shows itself as a stable and reliable app what is crucial for important 
business conversations.
I recommend!
