Common Activation Issues

Mediation Server Challenges

ndash PrivatePublic IP settings

ndash Use G711 codec

ndash Single trunk firsthellipthen add redundancy

ndash Add security setting AFTER initial call success

Firewall Challenges

ndash Double-check Network Address Translation (NAT)

ndash Symptoms are 1-way audio clipping signaling timeouts that lead to fast busy

Test Using

ndash 1 DID for Auto-Attendant

ndash 1 DID for Voice Mail Access

ndash 1 DID for Conference Bridge

ndash 2 DID for Users

Building With Quality

Copyright copy 2010 IntelePeertrade Inc All rights reserved

Interconnection

ndash Use Public Internet first to validate call flow

ndash Move to VPN or Private IP connection if needed

Mediation Server

ndash SIP Trunk Redundancy (avoid maintenance downtime)

ndash Use 2 mediation servers or domain name server (DNS) for multiple trunks

Security Considerationsndash Virtual Private Network (VPN)

ndash Transport Layer Security (TLS) for signaling

ndash Secure Real Time Protocol (SRTP) for media

Quality Considerations

ndash Utilize provider trialinterop periodhellipis your network really ready

ndash SIP Trunk provider quality reporting

ndash Answer Seizure Ratio Post Dial Delay PESQMOS

Keys To Evaluate Providers

Geographic Coveragendash No single carrier provides 100 geographic coverage

ndash Make sure you ask about expected coverage areas upfront

ndash More challenging with centralized architectures

Caller ID (CID) Caller Name (CNAM)ndash Support varies by provider

Ask about SLAs amp Turn Around Timesndash SIP trunk turn up

ndash Adding Phone Numbers

ndash Moving Numbers to New Providers

Moving Numbers To New Providersndash Local Number Portability (LNP) amp Responsible Organization (RespOrg)

ndash Letter of Authorization (LOA)hellipsignature matters

ndash Copy of last phone bill to prove ownership

E911 Supportndash Need ldquoWave 14rdquo Microsoft Communications Server 2010 to fully support

ndash Support for 911 solutions available but check state-level requirements

Inbound amp outbound services providing DIDs Toll Free Numbers US and International Long

Distance

30 day evaluation period (no cost non-binding) to ensure IntelePeer is the right fit

ndash 10 DIDs provided for OCS auto-attendant voice mail access conference bridge and direct numbers for

testing

ndash 10 simultaneous call paths

ndash For evaluation connect via SIP trunk over public internet using OCS Mediation Server

ndash Connect to our production networkhellipnot a lab environment

Next steps for evaluation are to sign IntelePeer Mutual NDA and Evaluation Agreement
