  So, SIP origination is Direct Inbound Dial (DID, or DDI in european parlance) which allows callers on the PSTN to originate calls that end up at your SIP server.
  SIP termination allows calls which originate on your SIP server to terminate on the PSTN, i.e. to reach a non-voip line.
   
  Voip providers who provide "plans" are bundling 2 distinct services. Broadvoice, for example, does not expect its users to understand the terms, and just offers them what used to be called a "phone line" - the ability to make calls (termination) and recieve them (origination). 
   
  i hope this helps,

  I have an asterisk system im setting up for a small office (4 or 5 phones) and as im looking for a voip provider, i find that voip providers generally have unlimited plans, and those that offer sip origination and termination get charged for the minute, for their outgoing and incoming calls. 
   
  is there a difference in the backend architecture here? if so, what? or is this is just a difference in marketing terms and setup?
   
  for example, http://www.broadvoice.com offers an unlimited plan in the US for calls, though they never use the term sip origination and termination. they say their systems also supports asterisk.  
   
  yet http://www.bandwidth.com/content/enterprise?page=voice_services_origination_termination&campaignId=701300000000JBJ  calls it sip origination and termination
   
  any info is appreciated! thanks!
