  11. 11. Common Activation Issues  Mediation Server Challenges – Private/Public IP settings – Use G.711 codec – Single trunk first….then add redundancy – Add security setting AFTER initial call success  Firewall Challenges – Double-check Network Address Translation (NAT) – Symptoms are 1-way audio, clipping, signaling timeouts that lead to fast busy  Test Using – 1 DID for Auto-Attendant – 1 DID for Voice Mail Access – 1 DID for Conference Bridge – 2 DID for Users Copyright © 2010 IntelePeer™, Inc. All rights reserved. Page 11
  12. 12. Building With Quality  Interconnection – Use Public Internet first to validate call flow – Move to VPN or Private IP connection, if needed  Mediation Server – SIP Trunk Redundancy (avoid maintenance downtime) – Use 2 mediation servers or domain name server (DNS) for multiple trunks  Security Considerations – Virtual Private Network (VPN) – Transport Layer Security (TLS) for signaling – Secure Real Time Protocol (SRTP) for media  Quality Considerations – Utilize provider trial/interop period….is your network really ready? – SIP Trunk provider quality reporting – Answer Seizure Ratio, Post Dial Delay, PESQ/MOS Copyright © 2010 IntelePeer™, Inc. All rights reserved. Page 12
  13. 13. Keys To Evaluate Providers  Geographic Coverage – No single carrier provides 100% geographic coverage – Make sure you ask about expected coverage areas upfront – More challenging with centralized architectures  Caller ID (CID) / Caller Name (CNAM) – Support varies by provider  Ask about SLAs & Turn Around Times – SIP trunk turn up – Adding Phone Numbers – Moving Numbers to New Providers  Moving Numbers To New Providers – Local Number Portability (LNP) & Responsible Organization (RespOrg) – Letter of Authorization (LOA)…signature matters! – Copy of last phone bill to prove ownership  E911 Support – Need “Wave 14” / Microsoft Communications Server 2010 to fully support – Support for 911 solutions available, but check state-level requirements Copyright © 2010 IntelePeer™, Inc. All rights reserved. Page 13
  14. 14. Fast Start Program SIP Trunking for Microsoft OCS 2007 R2  Inbound & outbound services; providing DIDs, Toll Free Numbers, U.S. and International Long Distance  30 day evaluation period (no cost, non-binding) to ensure IntelePeer is the right fit – 10 DIDs provided for OCS auto-attendant, voice mail access, conference bridge, and direct numbers for testing – 10 simultaneous call paths – For evaluation, connect via SIP trunk over public internet using OCS Mediation Server – Connect to our production network…not a lab environment  Next steps for evaluation are to sign IntelePeer Mutual NDA and Evaluation Agreement IntelePeer SIP Trunking for Microsoft OCS 2007 R2 http://www.intelepeer.com/MicrosoftPartner/business-value.php Email: SIP@intelepeer.com 1-877-336-9171 Copyright © 2010 IntelePeer™, Inc.
