Frequently Asked Questions

Infinity VoIP

• What can Genesis support for SIP protocol that the VoIP card cannot?

  The transfer implementation is basically the same (both support refer-to and refer replaces) for blind and supervised transfers. Below outlines the differences between SIP and VoIP:

  • Genesis, by default, transmits on UDP port 5060 and expects a reply on 5060. Supports various UDP ports for signaling. (Infinity — cannot)
  • Genesis supports TCP protocol for signaling and the signaling port can be adjusted. (Infinity — UDP only)
  • Genesis supports its own fix up and doesn’t require ALG, so it can specify a public IP when needed. (Infinity — requires ALG)
  • Genesis does not transmit from various ports and expect a reply on 5060 — the VoIP card must behave this way.
  • Genesis supports TLS. (Infinity — does not)
  • Genesis supports Stir/Shaken. (Infinity — does not)
  • Genesis supports E.164 outbound. (Infinity — does not)
  • Genesis has better support for prefix/suffix dialing based on number dialed. (Infinity — prefix only on all call types)
  • Genesis supports route statements. (Infinity — does not)
  • Genesis supports more simultaneous calls/sessions. (Infinity — limited by hardware)

• How do I improve the music quality for my music on hold when using VoIP?

  The following note was received from several Amtelco customers: We bought the device below for our music on hold. Basically it’s a MP3 digital music-on-hold player with an hour or so of prerecorded music with periodic alternating man’s and woman’s voice assuring callers “we will be with you shortly.” You can download your own music for this device but the music that comes with it is fine and it has made a world of difference.

  http://www.onholdplus.com/ – the recommended model is: On Hold Plus 6000.

  This device connects to any Infinity or EVE port normally used for music on hold, if you have questions about connecting this device or an available port please contact Amtelco Field Engineering at 800.553.7679.
