How SIP Trunking Achieves Cost Savings “SIP Trunking Infrastructure cost reductions will allow Triton to realize ROI in as little as 3 months” Cameron Symonds, Director IT/TS, Triton Technologies Eliminates dual last mile facilities Mixed voice, video, data on same infrastructure More competitive market Greater geographic reach Improved flexibility “Fortune 1000-size organizations can save anywhere from 25-60% on their telecom expenses.” Sorell Slaymaker, Unified IT Systems “SIP Trunking can deliver savings of 30-50% for branch environments in mid-size and large enterprises” Gartner, Inc., 2009 “SIP Trunking returns an average savings of 25% vs. a traditional separate voice and data infrastructure” Global Crossings, 2011 NAT (network address translation): Extensively used today to resolve public IP address with private address of destination device Firewall traversal: Most firewalls can’t handle VoIP and block inbound VoIP calls Interworking: Not all IP PBXs and VoIP networks use SIP, or the same SIP implementation Transcoding: Multiple codecs in use today (e.g., narrow-band, wide-band)

SIP Trunking Looks Good; Upgrading PBX environment …“Not So Good” Continuing pressure to reduce operational costs Postponing/avoiding major capital expenditures Legacy (TDM, IP-PBX) infrastructures still work Effort to upgrade is slow and a distraction Carrying over certain existing functionality may not be supported
