How Voice Logica connects

OpenScape Business registers to Voice Logica as an Internet Telephony Service Provider (ITSP) (way 1). Voice Logica creates the trunk and gives you a server, a username and a password; in OpenScape it is one more provider next to your carrier.

• Calls the PBX routes to this provider are answered by the AI agent.
• The agent transfers callers back over the same provider with the extension’s number; with Use public number (DID) each station’s DID field rings that station.

Before you start

• S2M/T1/SIP trunks licences, one per simultaneous call to Voice Logica. A Warm transfer uses two until it connects.
• WBM in the Advanced profile (wizard) or Expert (codecs).
• At most 8 active ITSPs per system.

1. Create the connection in Voice Logica

Telephony - Trunks - Connect your PBX, pick Unify OpenScape Business and the agent. Keep the dialog open until it says Connected.

2. Add Voice Logica as a provider

1. WBM → Setup → Wizards → Central Telephony → Internet Telephony → Edit. Untick No call via Internet, then Add.
2. Base template. Provider Name VoiceLogic (10 characters at most), tick Enable Provider.
3. Gateway Domain Name = the server.
4. Provider Registrar: tick Use Registrar, host = the server, port 5060. Provider Proxy: the same host and port.
5. OK & Next → Add account: Internet Telephony Station = the username, Authorization name = the username, Password = the password.
6. Call number assignment = Use public number (DID), with a default number.
7. Set Upstream (Kbps) high enough for the calls you expect; it caps simultaneous calls. Check that the provider shows as registered.
8. Expert Mode → Telephony Server → Voice Gateway → Codec Parameters: G.711 A-law priority 1, frame size 20 ms, tick Transmission of DTMF Tones according to RFC2833.

3. Send calls to the agent

Use Expert mode → LCR (dial plan, routing table) to make a route, for example a code your staff dial, that uses the Voice Logica provider. To send a number, an attendant option or after-hours calls to the agent, forward that destination to an external number dialled over that route. Your Unify partner can confirm the best way for your release.

4. Let the agent transfer back to extensions

With Use public number (DID), calls from Voice Logica reach the station whose DID matches the number the agent sends. In Voice Logica, add each person as a transfer destination: an External destination with that number, or a User with that extension. Use Warm transfer, so the agent comes back and takes a message when nobody answers.

5. Check it works

• The dialog says Connected; the provider shows as registered in WBM.
• Dial the route: the call appears in Calls.

Good to know

• Change Extended SIP Provider Data only with Unify support.
• HiPath 3000 (older): SIP providers arrived in later releases through the HG 1500 board. If yours cannot add a SIP provider, use an ISDN gateway or forwarding.
