How to record calls

[Pander]

Hi all,

Someone has created a dictaphone application, but is it also possible to
record directly from (within) the (SHR=FSO?) dailer?

Use cases would be:
1) record received sound only
2) record transmitting sound only (dictaphone)
3) record conversation, both receiving and transmitting sound

Would it be viable to add this functionality to dailer, then a
dictaphone will be provided by dailer and an external dictaphone
application would not be needed or the functionality could be shared.

Secondly, what format would be desirable to record into? OGG?

Thanks,

Pander
