"""Client for the packetdial skill — NetSapiens SNAPsolution API v2.
|
|
|
|
Talks to the live PacketDial / OITVOIP reseller PBX at pbx.packetdial.com
|
|
(NetSapiens v44.4). voip.packetdial.com is the customer-facing white-label
|
|
portal and is NOT the API host — the programmable surface lives on pbx.
|
|
|
|
Auth: Bearer token. Two credential shapes are supported, tried in this order:
|
|
1. Static API key (`nsr_` reseller-scoped or `nss_` system) used directly as
|
|
the bearer token. Preferred for machine-to-machine.
|
|
2. OAuth2 password grant: client_id + client_secret + username + password
|
|
POSTed to /tokens, which returns a short-lived access_token (JWT).
|
|
|
|
Credentials are NEVER hardcoded. They are loaded at runtime from the SOPS vault
|
|
entry `msp-tools/oitvoip.sops.yaml`, or from environment overrides. As of the
|
|
skill's creation that vault entry does not yet exist — see SKILL.md for the
|
|
one-time provisioning steps.
|
|
|
|
Transport: prefers httpx if installed, else falls back to stdlib urllib so the
|
|
skill works on a bare Python install.
