DESCRIPTION
SIP Trunking is beginning to become a widely deployed offering from SP. One way of looking at SIP Trunking is outsourcing the essential feature of TDM interconnection from an "on premise" TDM gateway to a service from your SP. With more and more customers deploying SIP Trunking, it is important to understand what is required to successfully deploy this service and where the future of SIP Trunking is heading. In this presentation you will learn about how SP offer SIP Trunking Services and what is required for customers to successfully deploy this new Cloud service.

Cloud is a new computing paradigm. In Cloud, IT resources and services are abstracted from the underlying infrastructure and provided on-demand and at scale in a multi-tenant environment. Cloud has several characteristics:
• Information technology, from infrastructure to applications, is delivered and consumed as a service over the network• Services operate consistently, regardless of the underlying systems• Capacity and performance scale to meet demand and are invoiced by use• Services are shared across multiple organizations, allowing the same underlying systems and applications to meet the demands of a variety of interests, simultaneously and securely • Applications, services, and data can be accessed through a wide range of connected devices (e.g., smart phones, laptops, and other mobile internet devices)

Is outsourcing TDM Gateway by moving to SIP Trunking a good choice for a CLOUD Service ?
YES
1. Service Providers (SP) have a great deal of experience with TDM to IP Gateways
2. The service can be MORE reliable then traditional TDM Gateways on premise
3. The service is technologically more efficient (ie fewer IP translations) , which means quality improves
4. SP can offer additional service on top base service to increase their value add
5. SP can scale and monetize this service, they understand and have capacity to bill the service and as such will make the investments in this service
6. The function is not core to a high quality Enterprise UC deployment

Centralized SIP Trunk
§ Consolidated PSTN SIP trunks at HQ site§ Remote sites have SRST for phone backup,
but need TDM access for PSTN backup (1 FXO)§ Lower cost of equipment needed for
termination§ Bandwidth requirement increases as “PSTN”
calls from remote site now traverse WAN§ QoS concerns as RTP for remote site PSTN
calls traverse WAN twice§ Requires porting of all DIDs to aggregated SIP
trunks – geographic and SP challenges§ E911 locations tied to HQ as opposed to phone
location
Distributed SIP Trunks
§ Each site has its own SIP Trunk and CUBE for PSTN access § SIP trunk remains active during SRST§ RTP path is optimized§ Remote site CUBE also acts as local MTP and
SRST router § E911 locations tied to local site and hence
more accurate§ SP and customer need to provision dial plan
correctly to ensure optimal call routing§ Cost may not decrease as dramatically as
centralized solution

• In summary, there are three methods of deploying SIP Trunks today: centralized where trunks for all regions are centralized and provided only from a central location; distributed, where each regional office has SIP Trunk from the providers; and hybrid models where different solutions are provided for different types of traffic
Centralized Location of All SIP Trunks
Distributed Trunks to All Locations
Hybrid Trunk Deployment, Deploy Trunks Based on Function
All PSTN Trunks are removed from remote sites and replaced with SIP Trunks that terminate only at the central datacenter or headquarters. This HQ site receives and routes ALL PSTN traffic via SIP Trunks to Service Provider.
SIP Trunks are provided from the Service Provider to all sites. Each site removes their PSTN access and instead replaces it with SIP Trunks from the provider that terminate at the remote sites. Provider needs to route phone calls to remote site via SIP trunk at remote sites.
SIP Trunks are added in Headquarters and /or remote sites to complement PSTN trunks. Dialplan is altered so that traffic can flow across most effective trunk, and traffic can be effectively routed via both HQ and remote site Trunks.

• There is currently no standard for SIP Trunks that can provide the same level of consistency and interoperability of PSTN ISDN Trunks
• There are efforts underway in the industry to have more interoperability; various efforts are being lead by the SIP forum, ATIS, TISPAN
• The problem of interoperability is reduced by having a customer owned border element (CUBE) that can provide signaling interworking/normalization and transcoding
• This problem can be further reduced by having a Service Provider owned Border Element that acts as a demarcation point for signaling
• Customer should test before deployment of their first SIP Trunks solution, and replicate successful deployment procedure to ensure scaling

• SIP Trunks can typically use three different methods to supports FAX calls1. All calls are sent as G7112. Call sends a RE-INVITE to up-speed to G711 when a FAX tone is detected3. T.38 FAX capabilities are exchanged and fax relay is used
• SIP Service provides also occasionally offer a separate fax to -mail service using T.37 Store and Forward fax• Recommend that your SP support T.38
Fax MethodT.38 Fax Capabilities Exchanged
as Part of SIP Messages
All Call Sent as G711Fax Tone Is Detected and RE-INVITE to
up-speed to G711 Is sent
Pros § Highest fax success rates can be achieved§ Cleanest solution from signaling
and media point of view§ Use less bandwidth
than G711§ Fax and Voice calls differentiated
§ Most widely deployed§ Simplest solution
§ Provides benefits of least bandwidth with G729 call initially upspeeding to G711 if call is FAX§ Tone (2100Hz) can be mixed between
Modem and Fax§ Fax Pass-Through
Cons § Degree of interoperability§ Not offered by all Service
Providers
§ Consumes a large amount of bandwidth for all calls§ No ability to distinguish FAX calls from Voice
calls in CDRs
§ Each vendors support of RE-INVITEs is different§ Currently not supported with all Cisco
equipment

• Typical Supplementary ServicesPlacing call on HOLDForward on Busy/No Answer to Number within premiseTransferring call to another extensionCorrect billing for forwarded calls
• Testing of Supplementary Services before deployment is only way to ensure success
Create a test case for each service before deploymentReport findings to Service ProviderDetermine if lack of these functionality should effect deployment
• The supplementary service invoked over the SIP Trunk is not supported or understood by the far end SIP switch
For example, the signaling to place a call on hold and temporarily stop media can be done in one of several ways, all of them are compliant with the standard; mismatching methods may be supported between two SIP switches

• Voice Band Data (VBD) is used to send information such as credit card transactions or alarm system information over slow speed modem connections across the voice channel of an PSTN circuit
• Voice Band Data can work reliably up to 56K with TDM Trunks• With SIP Trunks cannot maintain a PCM clock sync ,so 56K connections are not possible; but medium speed
modem connections are possible over G711 (up to about 26.4K)• With compressed codecs (i.e. G729), you cannot reliable send modem tones over VoIP calls (G711 required)• VBD cannot be “guaranteed”, so an important consideration is whether there are PSTN circuits that can be left
to support this at the site where SIP Trunks are being considered; the most used types of VBD are:• Baudot connections for deaf users
• Credit card validation systems
• Security systems
• Pitney Bowes Postage Machines
• These systems should all be tested before a SIP Trunk for PSTN access is used as a replacement at

• Experience has shown that as customers deployed SIP Trunks for PSTN access, the experience for users has sometimes been “inconsistent” (i.e. one calls is great, next is not great)
• A “best practice” is to create a method of flagging calls that are very bad (either via CDRs/CMRs analysis or user feedback)
• Use data from CDRs/CMRs (i.e. Jitter, Packet Loss) to determine if there are trends; these statistics can be gathered from the Customer premise Border Element (ie CUBE) or CUCM
• Try to determine if quality issues correlate with specific events, such as dialing to some area codes or countries or specific times of day; service providers have different methods of routing that can effect quality
• Service providers should ensure that they have a method of measuring quality all the way to the customer premise; this can be used to distinguish their service from others

How to Successful adopt a Cloud Service
1. Read and review White papers on Communications Transformation• http://www.cisco.com/en/US/products/sw/voicesw/ps5640/prod_white_papers_list.html
2. Find out who offers Services in your region• Ask current provider or VARs, look at who provides Layer 2 connectivity
3. Understand what your Telecom PSTN costs are• Both costs of connections (T1/E1/Analog) and per minute costs• Use the Cost Estimate
4. Understand what your WAN costs are• Upgrading your IP to “gold” service WAN with your layer 2 providers• IP costs for SIP Trunk are not FREE (as is shown in many ROI calculators),
for toll quality voice
5. Deploy trial with some services• Outbound is easy as it does not require porting of phone numbers• Inbound does require porting of phone numbers to IP addresses and this
may not be as easy as SP promise
6. Monitor quality of deployment and use experience to determine where you want to be in five years—change the world
