DIAL PLANNING
Order numbers in continuous blocks
Specify allowed ranges to avoid system extension overlap
Dial full e.164 format to simplify digit manipulation and location dependance
Use least cost routing to terminate calls to Twilio POP closest to destination
[2‐9]11|011XXX.T|[2‐9]XXXXXXXXX|[2‐9]XX.T
STEVEN PLATT |
ROUTING & FAILOVER
Geolocate network egress to closest Twilio POP
Avoid ‘hair pinning' calls in Hub & Spoke networks
Round trip time must not exceed 300ms
Use DNS SRV to allow failover Twilio side

EMERGENCY SERVICES: 911 & 112
Cloud providers waive emergency call liability
Local termination may be required
Emergency services are highly regulated
US has e911 regulation requiring desk location tracking in some states
e112 regulation is pending in Europe
Developing markets often use manual PSAP routing (operators)
