Ingress

When using the Asterisk add-on, SIP Core can use it's ingress feature to connect to Asterisk without needing to port forward or setup SSL in Asterisk itself.

Technical Setup

When SIP Core detects the text.asterisk_addon_ingress_entry entity, (which is created by the Asterisk add-on on startup), it will use it's value (for example /api/hassio_ingress/1234567890abcdef) to create a ingress session using the Home Assistant API.

const resp: { session: string } = await this.hass.callWS({
    type: "supervisor/api",
    endpoint: "/ingress/session",
    method: "post",
});

This session is then stored in a cookie which Home Assistant's frontend uses when making requests to the assembled URL. The final URL will look like this:

template: {WS_PROTOCOL}://{HA_HOST}{INGRESS_ENTRY}/ws
wss://homeassistant.local/api/hassio_ingress/1234567890abcdef/ws

This method is borrowed from lovelylain's ha-addon-iframe-card,
and implemented by mrk-its in PR 131.

For more information on how the Asterisk add-on sets up ingress, see the Add-on documentation.
