Introduction

The interoperability compliance testing focuses on verifying inbound and outbound call flows between Sonus SBC 5XX0 and Skype for Business 2015.

Audience

This technical document is intended for telecommunication engineers for the purpose of configuring the Sonus SBC 5XX0 series aspects of the Virgin Media SIP trunk group together with Skype 2015. There will be steps that require navigating third-party equipment and the Sonus SBC Web browser user interfaces, as well as the Embedded Management Application (EMA). Understanding basic concepts for IP/Routing, SIP/RTP, and TLS are also necessary to complete the configuration and perform any troubleshooting, if necessary.

This configuration guide is offered as a convenience to Sonus customers. The specifications and information regarding the product in this guide are subject to change without notice. All statements, information, and recommendations in this guide are believed to be accurate but are presented without warranty of any kind, express or implied, and are provided “AS IS”.

Interoperability Test Results

The following table provides results from interoperability compliance testing.

Test Results

Interoperability Test No	Test Scenario	Test Setup and Result Summary	Test Status	Comments
IOP1	vendors eSBC response to SIP OPTIONS messages from SBC	No calls are required for this test. SIP trace to be captured for approx 60 seconds and checked for correct signalling. For each eSBC, the SBC will periodically send an OPTIONS request to the vendors eSBC to check if its SIP stack is reachable. If a SIP response 200 OK is received from the IP-PBX, the SIP trunk will be placed (or remain) in an In-Service state e.g. OPTIONS sip:ping@<ip-pbx_IP_Addr>:5060 SIP/2.0	Pass
IOP2	SBC response to SIP OPTIONS messages from vendor eSBC	No calls are required for this test. SIP trace to be captured for approx 60 seconds (depending on agreement) and checked for correct signalling. Vendors eSBC setup for Solution IP.Addr Mode eSBC configured to send OPTIONS messages to the SBC on a periodic basis. The SBC responds with SIP response 200OK - e.g. "OPTIONS sip:ping@192.168.1.10:5060 SIP/2.0" Check that the eSBC can simultaneously send SIP OPTIONS messages to both the solution SBC addresses.	Pass
IOP4	Basic test call from IP-PBX to PSTN line through SBC-A (using SBC-A IPV4 ip address).	IP-PBX line initiates call, Call is answered, IP-PBX line terminates call. Vendors eSBC setup for Solution IP.Addr Mode Call from the IP-PBX. Invite seen from eSBC to SBC-A, proxy authentication challenge returned to eSBC, re-invite with correct credentials from eSBC and call progresses as expected. e.g. Request-Line: INVITE sip:<B-party>@<SBC-A ip.addr TBD>:5060 SIP/2.0 To: sip:<B-Party>@<SBC-A ip.addr TBD> Check the wireshark trace and confirm that G.711 A law codec with 10 or 20ms packetisation is being used. Also check to see if INVITE contains Session-Expires header and that it is syntatically correct. Check for Supported Header to see if 'timer' is supported. Ensure response in 200 OK is compatible with INVITEand check for Required Header and if it contains 'timer'. (x-ref IOP9)	Pass
IOP5	Basic test call from IP-PBX to PSTN line through SBC-B (using SBC-B IPV4 ip address)	IP-PBX line initiates call, Call is answered, IP-PBX line terminates call. Vendors eSBC setup for Solution IP.Addr Mode Call from the IP-PBX. Invite seen from eSBC to SBC-B, proxy authentication challenge returned to eSBC, re-invite with correct credentials from eSBC and call progresses as expected. e.g. Request-Line: INVITE sip:<B-party>@<SBC-B ip.addr TBD>:5060 SIP/2.0 To: sip:<B-Party>@<SBC-B ip.addr TBD> Check the wireshark trace and confirm that G.711 A law codec with 10ms packetisation is being used.	Pass
IOP7b	Called Number format - vendors eSBC to soft switch number normalisation - Global Dial Plan Test eSBC capability to send the called number in one of the following Global number formats (user part of Request & To URIs) 0yyyyyyyyyy (where y refers to any number, calling party = national) +44yyyyyyyyyy (where y refers to any number, calling party = national) +yyyyyyyyyy (where y refers to any number, calling party = international) yyyyyyyyyy (where y refers to any number, calling party = unknown)	SBC to be configured for Global calling plan. IP-PBX line initiates call to PSTN line, Call is answered. IP-PBX line terminates call. Configure the eSBC to present the called number in the user part of the Request & To URIs to be sent in one of the following formats 0yyyyyyyyyy (where y refers to any number, calling party = national) +44yyyyyyyyyy (where y refers to any number, calling party = national) +yyyyyyyyyy (where y refers to any number, calling party = international) yyyyyyyyyy (where y refers to any number, calling party = unknown)	Pass
IOP8b	Calling Number format - vendors eSBC to soft switch number normalisation - Global Dial Plan Test eSBC capability to send calling number in one of the following Global number formats (user part of FROM & PAI URIs) 0yyyyyyyyyy (where y refers to any number, calling party = national) +44yyyyyyyyyy (where y refers to any number, calling party = national) 00yyyyyyyyyy (where y refers to any number, calling party = international) yyyyyyyyyy (where y refers to any number, calling party = unknown)	SBC to be configured for Global calling plan. IP-PBX line initiates call to PSTN line, Call is answered. IP-PBX terminates call.
