Session Initiation Protocol (SIP) has become the prevailing method of delivering

voice-over data connections. Like PRI service, SIP provides 

  • Caller ID
  • Direct Inward Dialing (DID)

but it’s generally more flexible and scalable than traditional digital voice services. 

Rest assured, Bear Telecom Solutions will procure the correct SIP provider for you, and ensure that this complex service is properly designed and implemented with your IP PBX.
