Deutsche Telekom SIP-Trunk

Patton SmartNode products integrate IP and TDM communications for Enterprise and Carrier access networks, offering VoIP gateways combined with IP access routing, WAN transmission, and transcoding functionality. SmartNode scales from 1 to 32,768 VoIP or fax calls with various telephony interfaces including analog FXS/FXO and digital ISDN BRI, PRI, DS3 and STM-1.

This document includes a general overview of the requirements and provides the necessary configuration to interconnect Patton SmartNode VoIP Gateway / eSBC devices with the NGN Platform of Deutsche Telekom through the SIP interface CompanyFlex SIP-Trunk (Technical Specification 1TR119) or DeutschlandLAN SIP-Trunk (Technical Specification 1TR118).

CompanyFlex SIP-Trunk and DeutschlandLAN SIP-Trunk are SIP-Trunking services of Deutsche Telekom AG, which are available to Business customers.

Certified SmartNodes
In scope of these tests, Patton SmartNode VoIP Gateways & eSBCs have been tested in the 3rd-Party Lab of Deutsche Telekom in Bonn.

Recommended Firmware version for 1TR119 : Trinity 3.18 and higher

Recommended Firmware version for 1TR118 : Trinity 3.17.1 and higher
Following Patton equipment has been tested:

  • Analog Gateways interconnecting analog devices (phone, fax) to SIP-Trunk

  • ISDN Gateways interconnecting Legacy ISDN PBX (BRI, PRI) to SIP-Trunk

    • PRI (S2M) models

    • BRI models

  • eSBC (Enterprise Session Border Controller) for SIP-SIP and mixed connectivity

Note: Limitation concerning the virtual SN (vSN), SN5300 and SN5600 (products with no physical DSPs on-board): with the new Soft-DSP functionality, SRTP is supported, but no transcoding.

Test Environment

The tests performed in the 3rd-Party Lab involved Patton SmartNode Gateways / eSBCs with analog & ISDN devices connected through FXS & BRI interfaces. Customer tests have also been performed with a PRI PBX. Additionally, specific tests with SIP hard- and softphones on LAN side of SBC have been used to test SIP-SIP interworking (Yealink T41S as SIP phone, and MicroSIP as SIP softphone).

As displayed in the figure above, SIP and RTP termination is realized between Patton Gateway / eSBC and the NGN-Softswitch, meaning that the SIP-Trunking functionality on the IAD shall be disabled for this scenario.

Fax Calls
