Audience: Avaya IP Office admin or certified reseller. Time: 20 to 30 minutes. Releases: 10.x and 11.x (current).

​
Prerequisites

  • Avaya IP Office admin / Manager access
  • SIP Trunk Channels licence on the IP Office
  • Outbound UDP 5060 allowed on the edge firewall
  • PBX public IP or FQDN

​
Step 1: create trunk in SmartAlex

SIP Trunk wizard, pick Other. Avaya doesn’t have a dedicated preset; Generic works. Use digest auth. Save credentials.

​
Step 2: add the SIP trunk in IP Office Manager

1

Open IP Office Manager

Connect to the IP Office. Navigate to Line then right-click, then New, then SIP Line.
2

SIP Line tab

  • ITSP Domain Name: sip.voice.getsmartalex.com
  • Send Caller ID: Diversion Header
  • Country Code: (your country code, e.g., 27 for SA)
  • Incoming Supervised REFER: Auto
  • Outgoing Supervised REFER: Auto
  • Send 302 Moved Temporarily: Off
3

Transport tab

  • ITSP Proxy Address: sip.voice.getsmartalex.com
  • Network Configuration: Layer 4 Protocol = UDP, Port = 5060
  • Use Network Topology Info: System
  • Calls Route via Registrar: checked
4

Call Details tab

  • Add a new SIP URI.
  • Incoming Group: 99 (or your preferred group)
  • Outgoing Group: 99
  • Max Sessions: match the SmartAlex concurrent-call limit
5

VoIP tab

  • Codec Selection: Custom
  • Selected Codecs: G.711 ULAW 64K, G.711 ALAW 64K
  • Fax Transport: None
  • DTMF Support: RFC 2833
  • Media Security: Disabled (or Preferred for SRTP if configured)
6

Save and verify

Save configuration to IP Office. Check SIP trunk status in System Status: should show “InService”.

​
Step 3: short codes (outbound, optional)

Short Codes, add a code like 9N that dials N through Line Group 99 (the SmartAlex trunk group).

​
Step 4: inbound call route

Incoming Call Route, add a route: Bearer Capability Any Voice, Incoming Line Group 99, Destination to your desired hunt group or extension that will hand off to SmartAlex (typically the main auto-attendant destination you want to replace). For a SmartAlex-provisioned DID, you don’t need an inbound route on Avaya.

​
Step 5: extensions and agent

Populate extensions in SmartAlex. Link agent.

​
Step 6: test

Dial. Transfer.

​
Avaya-specific notes

  • Licensing: each SIP trunk channel needs a licence. Verify sysmon shows available channels.
  • SBC requirement: Avaya Session Border Controller (SBCE) is recommended in enterprise deployments for SIP-side security. SmartAlex works with or without SBCE.
  • Caller ID Name (CNAM): IP Office can substitute display names via the Calling Line Directory; this is independent of the SIP transfer mechanism.
  • Release 11: newer releases handle REFER more cleanly. If on an older release (10.0 or earlier), upgrade before deployment.
  • Session Border Controller for Enterprise (SBCE): if you terminate SIP on SBCE, configure the trunk on SBCE’s side with identical parameters, then point IP Office at SBCE.
