LiveKit SIP Outbound call test

This CLI runs a E2E test for SIP outbound calls.

Prerequisites

• Two LK servers with SIP: LK1 (outbound) and LK2 (inbound). Can be the same server.
• Two SIP phone numbers: NUM1 (outbound) and NUM2 (inbound).
• SIP Trunks associated with those numbers: TR1 (for NUM1) and TR2 (for NUM2).
• SIP Dispatch Rule for inbound: DR2 (for TR2 and NUM2). With optional PIN.
• Two LK rooms: RM1 (on LK1) and RM2 (on LK2).

}

Trunk config for TR2

{
    "inbound_addresses": [],
    "inbound_numbers": ["<NUM1>"],
    "outbound_number": "<NUM2>"
}

Dispatch Rule config for DR2

{
    "trunk_ids": ["<TR2>"],
    "rule": {
        "dispatch_rule_direct": {
            "room_name": "<RM2>",
            "pin": "<PIN>"
        }
    }
}
