Upstream bandwidth of 384kps should be sufficient for an office with 5 
phones, assuming up to four are being used at a time (SIP channels 
require ~80kps each). Some QoS will definitely help keep the voice 
packets from competing with uploads.

If you've got Linux on your gateway (and all the kewl kids do), you can 
give Wondershaper a try:

You tune it for your bandwidth speeds and it does the rest.
