Analog Trunk​​ 

Resumen​​ 

The analog trunk protocols allow callers to enter tone only, numeric display, alphanumeric and voice pages. Analog trunks are supported within the Verizon Business network for incoming, outgoing, and two-way traffic and direct inward and outward dialing.​​ 

Benefits​​ 

  • Two-way calling. The direct inward-outward dialing (DIOD) trunks offer inward and outward calling.​​ 
  • One trunk group. Traffic studies are easier to evaluate in terms of traffic capacity/requirements.​​ 
  • Direct station dialing. Incoming calls are automatically directed to the station’s user without attendant assistance. This feature reduces the requirement for attendant positions, reducing or eliminating attendant labor costs.​​ 
  • Analog trunking. No additional equipment is needed to replace existing DID trunks.​​
