We have created Webhook Subscription for getting missed calls.
We are using "/restapi/v1.0/account/~/telephony/sessions?direction=Inbound&missedCall=true" to get all missed calls/voice calls.
Webhook works good as we get all call information but somehow for some number we get only extention value(101) instead of phone number i.e
[to] => Array
(
[phoneNumber] => 101
[name] => Sneha Rao
[extensionId] => 712273005
                )
.
is there any way to get actual phone number instead of extention number?
