How Voice Logica connects

Section titled “How Voice Logica connects”

The OXO registers a SIP trunk to Voice Logica (way 1) as a public SIP gateway in OMC. Voice Logica creates the trunk and gives you a server, a username and a password.

  • Calls the OXO routes to this gateway (ARS prefix) are answered by the AI agent.
  • The agent transfers callers back over the same trunk; the OXO rings the extension through its public numbering plan (DDI).

Without an IP trunks licence, the OXO can instead take Voice Logica as a SIP extension through an edge device (way 2). The OXO’s SIP extensions listen on port 5059.

Before you start

Section titled “Before you start”
  • An IP trunks licence: OMC → Hardware and Limits → Software Key Features.
  • Enough VoIP-trunk channels: Voice Over IP → VoIP: Parameters. A Warm transfer uses two until it connects.

1. Create the connection in Voice Logica

Section titled “1. Create the connection in Voice Logica”

Telephony - Trunks - Connect your PBX, pick Alcatel-Lucent OXO and the agent. Keep the dialog open until it says Connected.

2. Configure the OXO in OMC

Section titled “2. Configure the OXO in OMC”
  1. External Lines → List of Accesses: make the VoIP trunk channels public trunks; add them to a trunk group in External Lines → List of Trunk Groups.
  2. Numbering → Automatic Routing Selection → Index of Gateway Parameters: Target Domain Name = the server, Default Transport Mode UDP, Registration = Requested, Registrar Name = the server, Port 5060, Expiration Time 3600, DTMF = Out-of-Band (RFC 4733).
  3. SIP Accounts: Login and Registered User Name = the username, Password = the password.
  4. Voice Over IP → VoIP: Parameters → Codecs: G.711 A-law first.

3. Send calls to the agent

Section titled “3. Send calls to the agent”

Numbering → Automatic Routing Selection: a prefix whose destination is this gateway and trunk group. Point an attendant group overflow, a DDI or an after-hours destination at that prefix.

4. Let the agent transfer back to extensions

Section titled “4. Let the agent transfer back to extensions”

Map incoming numbers from the trunk to extensions in the public numbering plan (DDI). Then, in Voice Logica, add the extensions as transfer destinations: an External destination with the extension number, or a User with that extension. Use Warm transfer.

5. Check it works

Section titled “5. Check it works”
  • The dialog says Connected; the trunk’s SIP logs in Voice Logica show each REGISTER and our reply.
  • Dial the ARS prefix from an extension: the call appears in Calls.

Good to know

Section titled “Good to know”
  • Static NAT on the OXO needs release R10 or later; on older releases use an edge device.
  • These steps follow a carrier’s OXO guide; menu names can differ by release. Your Alcatel business partner can confirm them.
