Document Overview

This document outlines the configuration best practices for the Ribbon solution covering the Ribbon SBC Core (SBC 5K, 7K, SWe) when deployed as a proxy between native Zoom Client and Zoom Cloud.

A ​Session Border Controller​ (​SBC​) is a network element deployed to protect​ ​SIP​-based Voice over Internet Protocol​ (VoIP) networks. ​Early deployments of SBCs were focused on the borders between two service provider networks in a peering environment. This role has now expanded to include significant deployments between a service provider's access network and a backbone network to provide service to residential and/or enterprise customers. ​The interoperability compliance testing focuses on verifying inbound and outbound call flows when Ribbon SBC 5K/7K/SWe is deployed as a proxy between native Zoom Client and Zoom Cloud.

Ribbon SBC 5K/7K/SWe is deployed on the customer site in order to meet the following customer requirements:

  • Ribbon SBC Core acts a proxy, prevents direct TLS access from Zoom Client to Zoom Cloud through public internet.
  • B2B Encryption of both signaling (TLS) and media (SRTP).
  • Topology hiding - Zoom customers enterprise internal network is totally hidden from public internet.
  • Advanced routing capabilities - Ribbon SBC solutions may add some advanced routing capabilities that would enable to connect additional devices, third party carriers (BYOC), PBX, etc.

The interoperability compliance testing focuses on verifying inbound and outbound call flows between Ribbon SBC Core & Zoom Cloud.

This guide contains the following configuration sections: 

  • Section A: Ribbon SBC Core Configuration
    • Captures general SBC Core configurations for deploying SBC as a proxy between native Zoom Client and Zoom Cloud.
  • Section B: Zoom Configuration
    • Captures the Zoom configuration.

  • All basic calls, along with the supplementary features like call hold, call transfer, and conference can be tested with configurations from Section A and Section B.

  • Advanced supplementary features can be configured on Zoom as mentioned in Supplementary Services Configuration on Zoom. These cover:

    • Auto Receptionist

    • Call Flip

    • Shared Line Appearance (SLA) or Call Delegation

    • Shared Line Group (SLG) 

SBC 5x10, 5400, 7000 and SWe are represented as SBC Core in the subsequent sections.

Non-Goals

Document workflow

Section A: SBC Core Configuration

The following SBC Core configurations are included in this section:

  1. Network and Connectivity
  2. Static Routes
  3. TLS Configuration on Ribbon SBC Core

  4. Zoom Client Leg Configuration
  5. Zoom Server Leg Configuration

1. Network and Connectivity

Ribbon SBC is as shown below:

Ribbon SBC


Mgmt is an RJ45 port and is the management interface of the SBC.

Media 0/Media1 depicted as pkt0/pkt1 are RJ45 ports. Media 0 and Media 1 are used in the current deployment and the same interfaces can be used in SBC Core 5K , 7K (appliance based). 

For the SBC SWe (virtualized platform), the logical pkt0/pkt1 interfaces must be mapped to a physical port.

2. Static Routes

Static routes are used to create communication to remote networks. In a production environment, static routes are mainly configured for routing from a specific network to a network that can only be accessed through one point or one interface (single path access or default route).

Tip
  • For smaller networks with just one or two routes, configuring static routing is preferable. This is often more efficient since a link is not being wasted by exchanging dynamic routing information.
  • For networks that have a LAN-side Gateway on Voice VLAN or Multi-Switch Edge Devices (MSEs) with Voice VLAN towards SBC Core, static routing configurations are not required.


Add the static route once Zoom Client Leg and Zoom Server Leg configurations are done on the SBC.

3. TLS Configuration on Ribbon SBC Core

Prerequisites:

  • For TLS to work, a trusted CA (Certificate Authority) is needed. In this scenario, GoDaddy is used as a Trusted CA.
  • Make an entry of Ribbon SBC Core private IP in the Public DNS. In this scenario, Godaddy public DNS is used.
  • Digicert Root Certificate is required on public side of Zoom.
  • Enable Zoom Server with TLS/SRTP.

Generate a CSR with OpenSSL 

# To create a Certificate Signing Request (CSR) and key file for a Subject Alternative Name (SAN) certificate with multiple subject alternate names, complete the following procedure:
  
Create an OpenSSL configuration file (text file) on the local computer by editing the fields to the company requirements.
  
Note 1: In the example used in this article the configuration file is req.conf.
  
Note 2: req_extensions will put the subject alternative names in a CSR, whereas x509_extensions would be used when creating an actual certificate file.
  
[req]
        distinguished_name = req_distinguished_name
        req_extensions = v3_req
        prompt = no
        [req_distinguished_name]
        C = US
        ST = VA
        L = SomeCity
        O = MyCompany
        OU = MyDivision
        CN = www.company.com
        [v3_req]
        keyUsage = keyEncipherment, dataEncipherment
        extendedKeyUsage = serverAuth
        subjectAltName = @alt_names
        [alt_names]
        DNS.1 = www.company.com
        DNS.2 = company.com
        DNS.3 = www.company.net
        DNS.4 = company.net
  
Make sure there are no whitespaces at the end of the lines.
  
#Run the following commands to create the Certificate Signing Request (CSR) and a new Key file:
openssl req -new -out company_san.csr -newkey rsa:2048 -nodes -sha256 -keyout company_san.key.temp -config req.conf
  
#Run the following command to verify the Certificate Signing Request:
openssl req -text -noout -verify -in company_san.csr
   
# After receiving the CSR with above information, provide it to CA (Certificate Authority). You will then receive the proper CA signed certificate in .crt format that is convertable into other formats using openssl.
 
# By default, you should receive two or more certificates from CA (depanding upon your CA). One is the SBC certificate, and other is CA's root and intermediate certificate.
 
# Upload the certificates to the SBC at /opt/sonus/external and convert them into SBC-readable format, i.e. SBC certificate is in .pem or .p12 format and root certificate is in .cer or .der.
  
#Converting .crt to .pem USING OPENSSL for SBC certificate.
openssl x509 -in sbc_cert.crt -out sbc_cert.der -outform DER
openssl x509 -in sbc_cert.der -inform DER -out sbc_cert.pem -outform PEM
  
#After generating sbc_cert.pem file, convert it to .p12 format using below command and the location of the certificate key.
openssl pkcs12 -export -out sbc1_cert.p12 -in sbc_cert.pem -inkey /opt/sonus/company_san.key.temp
  
#CONVERTING CRT to CER USING OPENSSL for CA's root and intermediate certificate.
openssl x509 -in root_cert.crt -out root_cert.cer -outform DER
  
After converting all these certificates upload them on SBC at /opt/sonus/external location.

This Zone groups the set of objects used for communication towards Zoom.

set addressContext default zone ZOOM id 6
set addressContext default zone ZOOM remoteDeviceType appServer
commit

6.4 SIP Signaling Port

Set the SIP Signaling port, which is a logical address used to send and receive SIP call signaling packets and is permanently bound to a specific zone.

Replace "x.x.x.x" with the SIP Signaling Port IP address of the SBC towards Zoom.

set addressContext default zone ZOOM sipSigPort 7 ipInterfaceGroupName LIF2
set addressContext default zone ZOOM sipSigPort 7 ipAddressV4 x.x.x.x
set addressContext default zone ZOOM sipSigPort 7 portNumber 5090
set addressContext default zone ZOOM sipSigPort 7 tlsProfileName ZOOM_TLSPROF
set addressContext default zone ZOOM sipSigPort 7 transportProtocolsAllowed sip-tls-tcp
set addressContext default zone ZOOM sipSigPort 7 mode inService
set addressContext default zone ZOOM sipSigPort 7 state enabled
commit

Attached the TLS Profile created earlier ZOOM_TLS_PROF.

There are a few areas that result in a TLS negotiation issue. One area involves assigning the incorrect port. Ensure the following are accomplished: 

  • Zoom listens on port number 5091 (default setting).

  • Configure port number 5090 on Zoom IP-Peer since Ribbon SBC Core increments the port by 1 when the transport protocol is TLS.

6.5 IP Peer

Create an IP Peer with the signaling IP address of ZOOM and assign it to ZOOM Zone.

Replace "x.x.x.x" with the Zoom SIP signaling IP.


set addressContext default zone ZOOM ipPeer ZOOM_IPP ipAddress x.x.x.x
set addressContext default zone ZOOM ipPeer ZOOM_IPP ipPort 5090

Section B: Zoom Configuration

Login to Zoom Go account Web portal at https://go.zoom.us/.

This section describes the following Zoom configurations:

  1. Adding SBC FQDN in Zoom portal
  2. Configuring Zoom User
  3. Configuring supplementary services configuration on Zoom

Adding SBC FQDN in Zoom Portal

  1. Navigate to Phone Systems Management > Company Info > "Site name" > Settings > Proxy > Zoom Phone Local Proxy
  2. Add the SBC FQDN (Internal) and Port as shown below, Save and Apply the configuration.

    Add External Number

    SBC FQDN "zoom.customers.interopdomain.com" should resolve to private IP and the entry for the same should be done in public DNS.

    Anonymous Call - *67 is a feature access code to enable Anonymous call. Zoom app shows the following notification when dialed *67

    "Caller ID blocking is not guaranteed to be effective in all countries or regions".
