The deployment model covered in thisapplication note utilizes Verizon’s Private IP (commercial MPLS network) to access Verizon IP Trunking. Supplemental guidelines are alsoincluded for using Verizon IP trunking to interface to their IP-based Contact Center Service or IPCC. Please note that in the context of thisdocument, “IPCC” refers to a cloud-based Contact Center product from Verizon, and should not be confused with a Cisco product. Additionalsupplemental guidelines are provided for an EMEA configuration.Testing was performed in accordance with the test plans for the Verizon IP trunking (US and EMEA), and IP Contact Center services. Allfeatures were verified.Although this document does not detail the results of the testing performed it provides the essential configurationsrequired for SIP interoperability with Cisco UCM/Cisco UBE and the Verizon IP Trunking and IPCC services.Verizon IP Trunking OverviewVerizon IP trunking services simplify management of your network and can help drive operational efficiencies. They do this by consolidatingyour voice services onto a SIP-based VoIP network, thereby optimizing your data IP network, and controlling costs associated with maintainingtraditional TDM local lines, trunks, and dedicated PRI circuits. Verizon also offer a native IP Trunking option that provides a SIP trunk directlyto your IPPBX, and an IP Integrated Access option that leverages a gateway device so you can interface with legacy Key or PBX systems.And, Verizon’s latest Burstable Enterprise Shared Trunking (BEST) feature enhancement allows you to share all your voice trunking resourcesacross your enterprise and lets you use idle trunk capacity in one location to accommodate a traffic increase in another location. BEST helpscontrol costs, as fewer concurrent calls need to be purchased at each location and resources can be shared to provide time of day benefits andpeak usage management.Verizon IPCC OverviewVerizon VoIP Inbound is a component of the IP Contact Center (IPCC) portfolio of internetworking services, which tightly couples signalingand functionality from the Advanced Toll Free and IP networks to deliver the intelligent routing and call treatment required by contact centers.The IPCC services are network-based and include IP Interactive Voice Response (IVR) in addition to VoIP Inbound.VoIP Inbound is standards-compliant and provides single-call service that allows PSTN-originated Toll Free calls to seamlessly terminate andtransfer to a SIP or TDM endpoints, without call re-originations that tie up CPE port capacity. VoIP Inbound includes advanced toll free features 2010 Cisco Systems, Inc.

including automatic ISDN User Part and SIP Error overflow for reliable termination to SIP or TDM devices anywhere; and, when combinedwith IP IVR, supports customer-driven pre/post call routing and/or call treatment and queuing for customers using Cisco ICMNetwork TopologyFigure 1. Typical Reference NetworkSystem ComponentsHardware Components CISCO UBE IOS version 15.1.2T2. Primary and Secondary CISCO UBE routers are used for high availability. Cisco Unified Border Element is an integrated Cisco IOS Software application that runs on various hardware platforms, for more details:http://www.cisco.com/go/cube Packet Voice Data Module (PVDM). You will need to install DSP modules on a supported ISR platform if you require MTP,Transcoding or Conference Bridge resources. These DSP resources are co-resident on the CISCO UBE routers in our lab configuration.

Note: RFC2833 is not currently supportedwhen using CTI Route-Points on CISCO UCM 8.0. An MTP resource is required to enable DTMF relay for any calls that utilize a CTIRoute-point. CISCO UBE performs Delayed-Offer to Early-Offer interworking of the initial SIP INIVTE from CISCO UCM. The Cisco UBE devicereceives the invite with no SDP then forwards the invite to the SIP network with SDP included. T.38 Fax relay is not supported by Verizon IP Trunking Service at this time Note: If you have a Cisco Fax Server or other T.38 Faxdevice, you will need to ensure that design considerations have been made to support this outside of the Verizon IP Trunking service.(i.e. T1 PRI) 2010 Cisco Systems, Inc.

Outbound SIP REFER with Replaces. CISCO UCM does not currently support generation of an outbound SIP Refer with replacesmessaging. CISCO UCM 8.0 can only support a single codec between the end device (i.e. IP Phone, ATA) and the SIP Trunk. A workaround forthis used during testing was to create multiple Regions and Device pools in order to control the codec selection prior to being presentedto the SIP Trunk. The end devices were configured with a specific Device Pool based on the codec used for off-net calls. This isespecially true for mid-call codec negotiation, for any calls that require changing of the initial negotiated codec the CISCO UBE devicewill insert a transcoder resource in order to avoid a codec mis-match between the SIP provider and the CUCM end-points. The CISCO UBE device must have transcoder resources configured on the Cisco UBE device and registered with CUCM to support themid-call codec change features on Cisco UBE. This feature allows for dissimilar Voice Class Codec configurations on the incoming andoutgoing dial peers. In order to comply with Verizon’s requirement of supporting g711u as a secondary codec for all calls and for performing Mid-CallCodec Negotiation, Cisco has provided an acceptable solution of providing this feature via the Cisco UBE by performing transcodingfrom Call Manager to SIP Trunk out to the networkFeatures Supported (IPCC)For a full list of supported SIP features please refer to the “Verizon Business IP Contact Center (IPCC) TrunkInterface Network Interface Specification” document.All Tests were performed according to the” Verizon Business IPCC Interoperability Lab Test Plan”These documents may be obtained by contacting your Verizon Business Account Representative.Known Limitations (IPCC) The IPCC service does not currently support SIP Diversion Headers The IPCC service does not support FAX Outbound SIP REFER with Replaces.
