Restcomm – Configure and Connect to External DID Providers

This tutorial will give you a short overview of what you need to do to connect Restcomm Cloud communication platform to DID providers like VoipInnovations, Bandwidth or Nexmo

Requirements

• Basic Knowledge of Restcomm
• Account from any of the above mentioned DID providers
• Install Restcomm as explained HERE
• Change Default Password as explained HERE

Step 1

• Go to $RESTCOMM_HOME/bin/restcomm
• open the file restcomm.conf for edit

To fill out the section # Network configuration

run the following command on your bash terminal

$> ifconfig 
enp19s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.3  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::f2bf:97ff:fe03:9e0a  prefixlen 64  scopeid 0x20<link>
        ether f0:bf:97:03:9e:0a  txqueuelen 1000  (Ethernet)
        RX packets 44916  bytes 36481273 (34.7 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 37502  bytes 5636746 (5.3 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

$> netstat -r
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
default         192.168.1.1     0.0.0.0         UG        0 0          0 enp19s0
192.168.1.0     0.0.0.0         255.255.255.0   U         0 0          0 enp19s0

Use the information above to fill out your configuration as shown in the example below:

NET_INTERFACE=enp19s0
PRIVATE_IP=192.168.1.3
SUBNET_MASK=255.255.255.0
NETWORK=192.168.1.0
BROADCAST_ADDRESS=192.168.1.255

Restcomm Ports to open on the firewall for NAT

• tcp:8080
• udp:5080
• udp:64535-65535
• tcp/udp: 5060

1. Port 8080 is used for the restcomm-management console over http
2. Port 5080 is used to make calls ex. sip:1234@Restcomm_IP:5080
3. Port 64535-65535 are used for media RTP traffic
4. Port 5060 is used for SIP

Step 2 – Setting the Static Public IP Adress

• Go to the file restcomm.conf under the section # PUBLIC IP ADDRESS
• Get the public IP address of the server on which Restcomm is installed

Use the public IP address to fill out the STATIC_ADDRESS below

# PUBLIC IP ADDRESS
STATIC_ADDRESS=SERVER_PUBLIC_IP_ADDRESS

ex. STATIC_ADDRESS=222.222.111.111

Step 3 – DID Provider Configuration

In the file restcomm.conf, go to the section # DID Provision provider variable declarations

# DID Provision provider variable declarations

PROVISION_PROVIDER=”               # values: VI (VoipInnovation), BW (Bandwidth), NX (Nexmo)
DID_LOGIN=”
DID_PASSWORD=”
DID_ENDPOINT=”
DID_SITEID=”

Enter your account details as provided by your Telco Service Provider.

• Save the restcomm.conf file
• start restcomm by running the script $RESTCOMM_HOME/bin/restcomm/start-restcomm.sh

You must stop ($RESTCOMM_HOME/bin/restcomm/stop-restcomm.sh) and start ($RESTCOMM_HOME/bin/restcomm/start-restcomm.sh )restcomm after making changes to the restcomm.conf file.
