AVAYA SIP Configuration Guide

Fonolo is compatible with all major call center platform vendors (Avaya, Five9, Genesys, Cisco, etc.). Fonolo has several different options for connecting to your AVAYA call center, including via a SIP connection over the internet.

This guide will outline the necessary steps, and information that we require, to set up a SIP connection between your AVAYA phone system and the Fonolo Cloud.

We also have an AVAYA specifc integration document that outlines in more detail the way Fonolo integrates with AVAYA, which can be found in our Downloads section.

1. Offer Message in Skill

The Fonolo Call-Back process begins with an offer message being played to the Client while they are waiting on hold. Each skill that you will be offering call-backs on should be configured to play an offer message, with a DTMF response (typically DTMF 1) initiating a transfer of the call to a Fonolo SIP Extension to begin the opt-in process. Offer messages typically say something like, “If you’d like to get a call-back rather than waiting on hold, press one now.”

You will need to configure:

• An offer message to be played on each skill (post-IVR) offering a call-back
• A DTMF response for an opt-in triggering a transfer of the call to a Fonolo SIP Extension

The initial offer message will need to be put in place in your existing messaging, based on whatever business rules are appropriate. Fonolo can offer some suggestions on frequency and threshold for making this offer, based on the success of some of our other customers.

2. VDN/SIP Extension Programming

When connecting to Fonolo via a SIP connection, we require one VDN per skill that you will be offering Call-Backs on. This dedicated VDN must give Fonolo the ability to dial directly into the skill, bypassing any IVR logic.

You will need to configure:

• Skill Name: Provide a label for each skill for easy identification within Fonolo.
• Skill VDN: Provide a VDN that will allow Fonolo to place a call directly into the skill.
• Fonolo SIP Extension: Fonolo will provide a unique SIP Extension for each skill that you will be offering Call-Backs on.

Once we have received the above skill information, we will provide one unique Fonolo SIP Extension per skill that you will use to transfer calls to for the opt-in process. Fonolo will automatically allocate the extensions used on the Fonolo end, from a 5-digit auto-allocated range assigned to you. If you require Fonolo to use a specific range, please let us know.

3. Firewall Configurations

For Fonolo to be able to connect to your AVAYA phone system, firewall rules will need to be applied to permit the required inbound and outbound traffic. Fonolo has 6 SIP Gateways that you will need to be able to connect to:

You will need to configure:

•  Fonolo IP Block 66.207.221.160/29 will need to be permitted for both inbound and outbound traffic in your firewall.
• The port UDP/5060 (preferred) or TCP/5060 (or TCP/5061 if using secure SIP) will need to be permitted (inbound and outbound).
• UDP port range matching the media ports on your phone system inbound (to you from Fonolo), and UDP/10000-20000 outbound (from you to Fonolo), will need to be permitted for RTP data.

4. Call Routing/Network Configurations

Fonolo uses several SIP Gateways for inbound and outbound connections to your AVAYA phone system, which need to be added within your phone system. Also, we will need a public IP address that Fonolo can use to reach your phone system. Lastly, two route patterns will need to be configured (if they do not already exist).

You will need to configure:

• Provide 1 or more public IP addresses that Fonolo can use to reach your AVAYA phone system. Load balancing or Fail-over configurations are acceptable.
• 66.207.221.161 and 66.207.221.162 are used for call transfers from your system to Fonolo on port UDP/5060 or TCP5060 or TCP/5061. You can load balance requests between these two SIP gateways.
• 66.207.221.163, 66.207.221.164, 66.207.221.165, and 66.207.221.166 are used for calls from the Fonolo system, to your AVAYA phone system.

  For example, to AVAYA Session Manager.

• We will need the UDP port range (min/max) for RTP data, which matches the media settings on your phone system.

  For example, this is configured via the IP Network Region settings on the AVAYA platform.

• One routing pattern that matches the inbound extension so Fonolo can connect to the skill directly.
• One routing pattern to place outbound calls to callers (by default, Fonolo formats outbound numbers as 11 digit numbers- e.g. 1xxxyyyzzzz).

5. NAT (optional)

In the case where your network has NAT (Network Address Translation) set up, Fonolo requires 1-to-1 NAT. Port-Based NAT will not work with the Fonolo Call-Back service.

You will need to provide:

• The public IP addresses of your NAT gateway that Fonolo can use to connect to your phone system.

6. IPSec VPN (optional)

Fonolo supports connecting to companies via a direct site-to-site IPsec VPN. For more details, see Connecting via an IPSec VPN.

7. Media

By default, Fonolo uses the following media settings for a SIP connection:

You will need to configure:

• g711u (μ-law), with a ptime of 20ms.
• RFC 2833 / RFC 4733 DTMF

8. Audio Prompts / Messaging (optional)

There are several audio prompts used by the Fonolo service, some presented to the caller, and some presented to the agent – all of which can be customized by you. This gives you the ability to keep a consistent voice as your callers’ transition on to the Fonolo platform, as well as customize verbiage so you can use preferred terminology.

Visit our Downloads page for a spreadsheet outlining all the files (with suggested messaging), that would be required to support the Fonolo Service.

You will need to provide:

• For each of the Audio Prompts listed in the spreadsheet, a voice file will need to be generated by your voice talent.
• Even when using the Fonolo Default Audio Files, you will still be responsible for the initial offer message (ex. “If you’d like to get a call-back rather than waiting on hold, press one now.”)
• The required format for all Audio Prompt files is .wav, 16bit, 8kHz, mono PCM.

9. Fonolo Portal Setup (optional)

Fonolo has an online portal (https://portal.fonolo.com/) where you can manage your Fonolo features and view call stats. To complete the set up of the Fonolo Portal for you, you will need to provide additional information on your company and phone system.

You will need to provide:

• A list of users who will have access to the Fonolo Portal, as well as their Role within the portal
  
  Stats Only User – Access to view graphs, call logs, and real time stats.
  Standard User– Access to the full portal and can make changes to features and set up new queues
  Admin – Same access as Standard but can manage other users
• The Hours of Operation for your phone queues, including holiday hours/closures.
• The Caller ID and Number that you would like your Clients to see when we call them back

10. Agent Training (optional)

In our experience, it is imperative to educate call center reps to give them an idea of what to expect when they receive a Fonolo call, and what the experience is like from a caller’s perspective.

We have provided a simple training document which can be found in our Downloads section, which can be used to enhance your existing training material, or can be provided directly to Agents. It typically does take the Agents a few days to “get the hang of things”, so the sooner they can be notified on when to start expecting Fonolo calls, the better.
