Avaya IPO Call2Teams Setup

Port Forwarding

Call2Teams registers users as SIP extensions on the Avaya IPO

The Call2Teams public IP addresses will be provided when you setup the PBX in Call2Teams

These public IP addresses will need to be allowed through the firewall to the Avaya IPO internal IP address to allow registration and voice traffic.

Depending on the method of registration, you will need to configure one of the below ports on the firewall.

5060 UDP (if registering via UDP)

5060 TCP (if registering via TCP)

Additionally, you will need to allow the below UDP port range (RTP ports for voice traffic)

46750 through to 50750 UDP (if using an Avaya IP500v2 PBX)

40750 through to 50750 UDP (if using an Avaya IPO Server Edition)

FQDN or Public IP Address

An FQDN or Public IP address can be used with Call2Teams. In our guide we have used an FQDN for the SIP Domain and FQDN
