So the functionality you need is really audio capture and computing power
and you think the best platform might be a turnkey video camera?
First, do a search on "Internet of Things botnet attack" to understand the
importance of good security. Often just changing passwords from the
default is adequate, so this doesn't necessarily rule out your proposed
solution.
Second, I would recommend you look into the Rasperry Pi computer. It is
touted as a minimalist Linux system retailing at $35. Attach an external
USB microphone, which depending on the quality you need, you may be able
to get for $10 anywhere up to hundreds of dollars.
Now, if you want to get a real discussion started, pick an encoding scheme
for RTP and proclaim that it is the best.

If it's just a prototpe, you could use a mobile phone. Network and sound
etc. is for free, either you'll find an app for android or it is trivial
to write it. Stackoverflow points me there:

why? there are plenty of cams sampling at a frequency equal to (or above) 44.1kHz.

It's a prototype project which must use a commercially available cam.

I'm only interested in the audio stream.

Meeting requirement (3), if it's intended literally, is going to
be a tough well to frack.

Is this a one-time project, or perhaps a prototype for a new product?
You might consider finding a used netbook computer, slapping a Linux
distro on it, and find some open source software to accomplish what you
want.
You could use the built in mic, or purchase a higher quality USB mic.
You don't mention you want to do anything with the video, but having a
computer would mean you could easily save a large number of images
locally. You could use the built in cam, or get an external one, or
both.
If the battery is still good, you have built in power backup.
Connectivity and security on the internet are already well known
quantities.
Just some thoughts since you haven't seemed to gotten any other answers.

I am looking for an IP camera that:
1. will allow me to programmatically connect to it (over UDP or TCP)
2. will send me the camera's microphone audio as RTP over UDP
3. supports the following audio sample rates: 8000Hz and any sample rate greater than or equal to 44.1kHz
Any recommendations?
