In this section:


Use these procedures to configure SBC and Lync servers to use the TCP protocol.

This page provides sample configuration therefore the values provided will vary based on the user environment.

The pathCheck Profile on Lync IP-Peer needs to be disabled while switching from TCP to TLS and vice versa.


Note

The  SBC 7000 system supports creating IP Interface Groups containing sets of IP interfaces that are not "processor friendly" (i.e. carried on physical Ethernet ports served by separate processors). However, restrictions exist regarding the usage of such Interface Groups.

(This ability does not apply to the SBC 5400 system which have only two physical media ports. IP interfaces from the two physical ports may be configured within the same IP Interface Groups without restrictions.)

For complete details, refer to Configuring IP Interface Groups and Interfaces.


Note
Ribbon recommends using the highest TLS version supported by both the SBC and the peer equipment.


Note

If a zone's sipSigPort is configured for transportProtocolsAllowed = sip-tls-tcp, the SBC increments the configured portNumber by 1 and uses it as the new port number for SIP over TLS signaling. The SBC then opens a TCP socket for SIP over TLS for the new TCP port number.

Example: When sipSigPort is configured with a portNumber of 5060 and transportProtocolsAllowed = sip-tls-tcp, the SBC listens on TCP port 5061 for SIP over TLS.

Global Configuration

This section provides global configuration steps.

  1. Create Codec Entry.

    1. Create G.711 Codec Entry or create G.711 with Silence Suppresion Codec Entry for Comfort Noise.

      set profiles media codecEntry G711_2833_20 dtmf relay rfc2833

set profiles media packetServiceProfile LYNC_PSP packetToPacketControl codecsAllowedForTranscoding thisLeg g711u otherLeg g711u

  3. Create IP Signaling Profile.

    set profiles signaling ipSignalingProfile LYNC_IPSP
set profiles signaling ipSignalingProfile LYNC_IPSP commonIpAttributes flags includeReasonHeader enable
set profiles signaling ipSignalingProfile LYNC_IPSP commonIpAttributes flags sendPtimeInSdp enable
set profiles signaling ipSignalingProfile LYNC_IPSP commonIpAttributes flags sendRtcpPortInSdp enable

set profiles signaling ipSignalingProfile LYNC_IPSP egressIpAttributes transport type1 tcp
set profiles signaling ipSignalingProfile LYNC_IPSP ingressIpAttributes flags sendSdpIn200OkIf18xReliable enable

  4. Create Feature Control Profile.

    set profiles featureControlProfile LYNC_FCP ipProtocolFlags useIpProtocol enable defaultCalledUser enable

  5. Create IP Interface Group.

    set addressContext a1 ipInterfaceGroup LIF1 ipInterface PKT0_V4 ceName LYNCSBC portName pkt0
set addressContext a1 ipInterfaceGroup LIF1 ipInterface PKT0_V4 ipAddress 10.10.10.11 prefix 24
set addressContext a1 ipInterfaceGroup LIF1 ipInterface PKT0_V4 mode inService state enabled

  6. Create Zone.

    set addressContext a1 zone LYNC_ZONE id 2
set addressContext a1 zone LYNC_ZONE domainName sbc.domain.com

  7. Create SIP Signaling Port.

    set addressContext a1 zone LYNC_ZONE id 2 sipSigPort 2 ipInterfaceGroupName LIF1 ipAddressV4 10.10.10.11 portNumber 5060 
transportProtocolsAllowed sip-tcp state enabled mode inService

  8. Create External DNS Group or local DNS group.

    # Configuring External DNS Group
set addressContext a1 dnsGroup EXT_DNS
set addressContext a1 dnsGroup EXT_DNS type mgmt server DNS1 ipAddress 10.10.10.10 state enabled
set addressContext a1 zone LYNC_ZONE dnsGroup EXT_DNS

# Configuring Local DNS Group
set addressContext a1 dnsGroup LOCAL_DNS
set addressContext a1 dnsGroup LOCAL_DNS localRecord DNS1 hostName lync.domain.com data 1 ipAddress 10.10.10.22 state enabled
set addressContext a1 dnsGroup LOCAL_DNS localRecord DNS1 hostName lync.domain.com data 2 ipAddress 10.10.10.23 state enabled
set addressContext a1 dnsGroup LOCAL_DNS localRecord DNS1 hostName lync.domain.com order roundrobin state enabled
set addressContext a1 dnsGroup LOCAL_DNS localRecord DNS1 state enabled

set addressContext a1 dnsGroup LOCAL_DNS localRecord DNS2 state enabled hostName med1.domain.com data 1 ipAddress 10.10.10.22 state enabled
set addressContext a1 dnsGroup LOCAL_DNS localRecord DNS3 state enabled hostName med2.domain.com data 1 ipAddress 10.10.10.23 state enabled

    You can configure centralized round-robin or strict round-robin for first-come first-served basis. Centralized round-robin is not recommended for high call traffic volume.

    For distributed round-robin over a large volume of traffic, configure the following:

    set addressContext a1 dnsGroup LOCAL_DNS localRecord DNS1 hostName lync.domain.com order roundrobin state enabled

  9. Create SIP Trunk.

    set addressContext a1 zone LYNC_ZONE sipTrunkGroup LYNC_TG media mediaIpInterfaceGroupName LIF1
set addressContext a1 zone LYNC_ZONE sipTrunkGroup LYNC_TG policy media packetServiceProfile LYNC_PSP
set addressContext a1 zone LYNC_ZONE sipTrunkGroup LYNC_TG policy signaling ipSignalingProfile LYNC_IPSP
set addressContext a1 zone LYNC_ZONE sipTrunkGroup LYNC_TG downstreamForkingSupport enabled
set addressContext a1 zone LYNC_ZONE sipTrunkGroup LYNC_TG signaling rel100Support enabled
set addressContext a1 zone LYNC_ZONE sipTrunkGroup LYNC_TG services dnsSupportType a-only

set addressContext a1 zone LYNC_ZONE sipTrunkGroup LYNC_TG signaling acceptHistoryInfo enabled
set addressContext a1 zone LYNC_ZONE sipTrunkGroup LYNC_TG mode inService state enabled

  10. Create IP Peer.

    set addressContext a1 zone LYNC_ZONE ipPeer LYNC_IPP
set addressContext a1 zone LYNC_ZONE ipPeer LYNC_IPP policy sip fqdn lync.domain.com fqdnPort 5068
set addressContext a1 zone LYNC_ZONE ipPeer LYNC_IPP pathCheck profile LYNC_OPTIONS hostName lync.domain.com hostPort 5068 state enabled

  11. Create Static Route

    set addressContext a1 staticRoute 10.10.10.22 32 10.10.10.1 LIF1 PKT0_V4 preference 100

If you are using IPv6 addressing, then Static Route, IP Peer and Ingress IP Prefix needs to be configured as per IPv6 addressing scheme.

Below is an example of IP interface group and SIP signaling port configuration in the Lync Side using IPv6 addressing scheme:

Example IP interface group and SIP signaling port configuration:
###Create IP Interface Group
set addressContext a1 ipInterfaceGroup LIF1 ipInterface PKT0_V4 altIpAddress fc00::10:f:f:f:11 altPrefix 64

###Create SIP Signaling Port
set addressContext a1 zone LYNC_ZONE id 2 sipSigPort 2 ipAddressV6 fc00::10:f:f:f:11

Configuration in the Service Provider Side (SP Network)

    set addressContext a1 staticRoute 20.20.20.22 32 20.20.20.1 LIF2 PKT1_V4 preference 100

Global Call Routing Configuration

The following is the global call routing configuration:

  1. Create Routing Labels.

    set global callRouting routingLabel LYNC_RL routingLabelRoute 1 trunkGroup LYNC_TG ipPeer LYNC_IPP inService inService
set global callRouting routingLabel SP_RL routingLabelRoute 1 trunkGroup SP_TG ipPeer SP_IPP inService inService

  2. Create Routes.

    set global callRouting route none Sonus_NULL Sonus_NULL standard 10 1 all all ALL none Sonus_NULL routingLabel LYNC_RL
set global callRouting route none Sonus_NULL Sonus_NULL standard 20 1 all all ALL none Sonus_NULL routingLabel SP_RL
set global callRouting route none Sonus_NULL Sonus_NULL username Sonus_NULL Sonus_NULL all all ALL none med1.domain.com routingLabel LYNC_RL
