Answering machine / Fax

[GoogleCodeExporter]

It would be nice you could record ongoing calls whenever you want at a click 
of, lets say, the camera button of your device.

It would be also nice to have a answering machine with fax capability (if you 
are using some fax friendly codec like ulaw or alaw).

Don't know if you noticed but for call recording there is the option in latest 
dev versions (available on download section). Or maybe your issue is about the 
fact you have to press menu > record and you'd like me to map it to a hard 
button? maybe not user friendly... and also not supported by all devices.

As for answering machine and fax interesting idea... However probably not a 
high priority for me for now. But as the project is opensource... if anybody 
want to make a contribution for that would be welcome. 
Could also be treated as a third party application. Don't know if this kind of 
feature is necessary for all users. So maybe a solution to provide in 
CSipSimple an API rich enough to allow a third party application to be an 
answering machine or a fax receiver could be a better solution.

I am not currently running the dev version, I will give it a try.

As for the fax machine and answering machine... well, it's possible to develop 
an independent sip piece of software for that. All it would be neccesary at the 
CSIP end is to know where to transfer the call.

Thinking aloud... how difficult do you think it could be to add IAX protocol in 
addition to SIP?

For IAX read my comments on issue 45 .

For answering machine after reflection, not relevant in a first time for the 
core CSipSimple app. However could be done as a third party application would 
make more sense. 
Besides, I'd say that the good approach to receive fax if a sip provider allow 
that is to use SIP message and directly get back a PDF file using SIP message 
with content type pdf (or png).
I think that fax feature is more relevant in the sip server than in the final 
client.

However why not, but I mean that's a really specific use case and should be 
treated by a specialized application. I know that there is some existing piece 
of gpl software that allow to use SIP for Fax. So I'll help anybody that want 
to integrate this kind of feature (fax / auto attendant) as a third party app 
that rely on CSipSimple but I think that integrate it directly in the core 
project is not a good idea. Plugin approach is better to do that (more user 
friendly and better in term of design).
