To say the least, yeah. At 3kbps and 20ms framing, it's only 7.5 bytes of payload per frame. RTP, UDP, IP, and Ethernet overhead are what - 60-ish bytes?

  60ish sounds right, though with Ethernet it's going to be padded to a minimum 64 bytes regardless. Might not matter depending what your bottleneck link actually uses though.

  You might have PPPoE on top of that with another 8 bytes.
