Note: Bandwidth doesn't support SIP with more than 6 characters prepended. 

The supported codec for 911 is g711. While a call may still traverse the Bandwidth Session Border Controller (SBC) with a different codec, there's no guarantee that this codec will be transcoded properly, thus leading the call to fail.

For more information, please see our 911 integration guide.
