Tariff in combination with pascom: Vodafone NGN Trunk

Since pascom 18.05, a trunk template for Vodafone NGN Trunks is available.

As the authentication to the Vodafone SIP server takes place via the your Internet connection IP address, configuring these trunks is only possible in a self hosted on-premise pascom phone system.

1. Your Account

After the purchase and activation of your Vodafone NGN trunk, you will receive a letter containing your account information. This document contains important information relating to your telephone connection:

Name Description Example
New number Phone number or number block for your telephone connection 0991/9881499 0..99
Extension length Number of extension digits should you have a number block 2 digital variables
SIP Username Telephony connection username XXXXXXXXX
SBC-IP IP address of the SBC which is only reachable via the telephone system IP.Enter the SBC IP from your access data here. (without leading 0s) XX.XXX.XXX.XXX
SIP Domain SIP Domain of the telephony connections pascom.ngn.vodafone.de
(For data proctection purposes exact numbers and data have been replaced with “X”)

2. Router preparation

Please note that SIP communication with the entered SBC is only possible from the phone system IP address. Should you use your pascom phone system inside your own network with a private IP address, please verify the necessary network settings on your firewall / router (NAT).

Inbound traffic from the Vodafone SBC must be forwarded onto the pascom phone system. For security reasons, the firewall rule should be exclusively limited to port 5060 UDP / 5061 TCP to port 5060 / 5061 of the phone system. Conversely, outbound traffic must be modified per NAT, as the Vodafone SBC only accepts data from the external IP from port 5060 / 5061 to port 5060 UDP / 5061 TCP of the connection. Finally, you must consider your phone system settings in terms of the range of RTP ports so that these packets are transmitted from the phone system via the firewall to the SBC.
