Document Overview

Use this configuration information to connect a Ribbon Session Border Controller (SBC) with a Microsoft Skype for Business version 2015 system and a Virgin Media SIP trunk.

This configuration information is applicable to the Ribbon SBC 5XX0 series and SBC 7XX0.

For more information about Ribbon SBC, refer to your Ribbon SBC product documentation http://ribboncommunications.com/.


Introduction

The interoperability compliance testing focuses on verifying inbound and outbound call flows between a Ribbon Core SBC and Microsoft Skype for Business 2015.

Audience

This technical document is intended for telecommunication engineers that configure the Ribbon SBC Core aspects of the Virgin Media SIP trunk group with the Microsoft Skype for Business 2015. This configuration requires access to a third-party server and the Ribbon SBC Web browser user interface, Embedded Management Application (EMA). Engineers require a basic understanding of  IP routing, SIP, RTP,  and TLS to configure and troubleshoot this solution.


The links are only internally to Ribbon partners and employees. They don´t work outside from the Ribbon Network.

Equipment

The following table lists the equipment and software used to complete the tests that a Virgin Media SIP trunk requires to connect with Ribbon software.

Features Not Supported

  • Microsoft Skype for Business 2015 does not support Busy line. There is no impact to the latest requirements from Virgin Media. 

  • Busy is not supported because there it all the time activated call waiting on all lines so they cannot be busy, if voice mail is activated, calls are forwarded there after some timeout.

  • Microsoft Skype for business 2015 does not support busy it has the option to either always forward to another number or to always forward to voice mail.

Test Results

The following table provides information about the tests that Ribbon performed to complete all scenarios that Virgin Media needs for his customers.

S.NoProcedureObservationResultComment
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 signaling.

For each eSBC, the SBC periodically sends 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 is placed or remains in an In-Service state.

e.g. OPTIONS sip:ping@<ip-pbx_IP_Addr>:5060 SIP/2.0

Pass
IOP2SBC 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 signaling.

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, for example:
"OPTIONS sip:ping@192.168.1.10:5060 SIP/2.0"

Verify that the eSBC can simultaneously send SIP OPTIONS messages to both the solution SBC addresses.

Pass
IOP4Basic test call from IP-PBX to PSTN line through SBC-A (using SBC-A IPV4 ip address).

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.
For example:
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 used.
Also check to see if INVITE contains the Session-Expires header and that the INVITE is syntactically correct. Check for Supported Header to see if 'timer' is supported. Ensure that the response in the 200 OK is compatible with the INVITE and verify that the Required Header contains 'timer'. (x-ref IOP9)

Conclusion

Ribbon successfully completed configuration and testing for the Ribbon SBC Core to interoperate with a Skype for Business 2015 system and a Virgin Media SIP trunk. All feature and serviceability issues were completed with the noted exceptions and observations.


Appendix A


  • For test case IOP13, Ribbon used NGT Lite software to enable text directly to emergency services.


IOP13



  • For test case IOP27, the following SMM rule was applied to match the case conditions:
IOP27 
set profiles signaling sipAdaptorProfile "PAID_CHANGE" state "enabled" advancedSMM "disabled" profileType "messageManipulation"
set profiles signaling sipAdaptorProfile "PAID_CHANGE" rule "1" criterion "1" type "message"
set profiles signaling sipAdaptorProfile "PAID_CHANGE" rule "1" criterion "1" message messageTypes "request" methodTypes "invite"
set profiles signaling sipAdaptorProfile "PAID_CHANGE" rule "1" criterion "2" type "header"
set profiles signaling sipAdaptorProfile "PAID_CHANGE" rule "1" criterion "2" header name "P-Asserted-Identity" condition "exist" hdrInstance "all"
set profiles signaling sipAdaptorProfile "PAID_CHANGE" rule "1" applyMatchHeader "one"
set profiles signaling sipAdaptorProfile "PAID_CHANGE" rule "1" action "1" type "header" operation "modify" headerInfo "fieldValue"
set profiles signaling sipAdaptorProfile "PAID_CHANGE" rule "1" action "1" to type "header" value "P-Asserted-Identity"
set profiles signaling sipAdaptorProfile "PAID_CHANGE" rule "1" action "1" from type "value" value "<PrgSkype1>; <sip:+441183374130@216.110.2.220:5060>"


  • For test case IOP28, you must select Enable forward P-Asserted-Identity data to set CLIR.

Select Control Panel > Voice Routing > Trunk Configuration

IOP28


  • For test case IOP29, IOP30, IOP32, to configure any kind of Call Forward in Microsoft Skype for Business Client you need to select the number to forward the call:


IOP32

 


  • For test case IOP34, by default, the Ribbon SBC does not forward RE-INVITE messages from Skype for Business to the Virgin Media SIP trunk.


IOP34



  • For test case IOP36, use the Microsoft Exchange admin center software to configure the Unified Messaging service. This allows Skype for Business to send 480 messages to Ribbon SBC 2000. You need to disabled Unified Messaging service


IOP36_1



IOP36_2

 
  • For test case IOP39, the following configuration needs to be changed on the SBC Ribbon in order to send the DTM inband:
IOP39 
configure
set profiles media codecEntry SKYPE_G711A_20ms_2833 dtmf relay rfc2833
set profiles media codecEntry SKYPE_G711U_20ms_2833 dtmf relay rfc2833
set profiles media codecEntry VIRGIN_MEDIA_G711A dtmf relay none
set profiles media codecEntry VIRGIN_MEDIA_G711U dtmf relay none
commit


  • For test cases IOP43 and IOP44, the following configuration needs to be changed on the SBC in order to send the Fax inband:
IOP43 and IOP44 
configure
set profiles media codecEntry FAX_G711A_20ms_2833 fax toneTreatment none
set profiles media codecEntry FAX_G711U_20ms_2833 fax toneTreatment none
set profiles media codecEntry VIRGIN_MEDIA_G711A fax toneTreatment none
set profiles media codecEntry VIRGIN_MEDIA_G711U fax toneTreatment none
commit


  • For test case IOP45, you must modify configuration settings in Skype for Business and SBC Ribbon in order to maintain a muted call, without sending RTP packets, for more than six minutes.

In Skype for Business you need to add the following lines by Shell:

Set-CsTrunkConfiguration -EnableSessionTimer $True
Set-CsTrunkConfiguration -RTCPActiveCalls $false -RTCPCallsOnHold $false.

For the Ribbon SBC, access the RTCP Options page to enable RTCP and Termination For Passthrough for the VIRGIN_MEDIA_PSP packet service profile.
