GOING GLOBAL

MULTIPLE GEOGRAPHIES

!  Need to work with service providers in each geography

!  Pricing will vary !  Provisioning time will vary

!  International charges become important

!  Obtaining phone numbers in various countries will require different procedures in different geographies

t

GOING GLOBAL

THE TWILIO WAY

!  Provision numbers in 50 different countries on one trunk

!  Automated routing to nearest Point of Presence for minimal latency

!  Automated selection of upstream carriers to couple best quality and lowest latency

t

DISASTER RECOVERY

WHEN THE NETWORK GOES DOWN…

!  Some, but not all, providers provide in-bound disaster recovery capabilities

!  These typically involve ���re-routing calls when the IP network is down

!  Several providers suggest a PSTN backup or redundant IP links using different carriers

t

DISASTER RECOVERY

THE TWILIO WAY

!  Can define alternate SIP endpoint to connect to

!  Alternatively can define full TwiML Scripts to fully control call flows

!  Replicate IVRs or take caller details for a call back

!  Even failover to a full WebRTC cloud solution

!  Also support NAPTR and SRV for load balancing across enterprise equipment

t

MONITORING

MONITORING THE SIP TRUNK

!  Most providers offer some type of monitoring portal, but monitoring is often not a highlighted capability

!  Typically usage and CDR records

!  Some provide more complex monitoring, including billing breakouts

!  Important to put in an SBC as a demarcation point (helps with debugging problems)
