Explanation
A Route Group in CUCM is exactly designed for this use case. It groups multiple gateways in a prioritized, ordered list and implements an automatic failover (hunt) mechanism: CUCM tries the first gateway; if it is unavailable or busy, it moves to the next, and so on. The administrator creates a Route Group containing: Houston GW (priority 1) → Bryan GW (priority 2) → Laredo GW (priority 3). This Route Group is then referenced by a Route List, which is in turn referenced by a Route Pattern for international calls. A single Route Pattern pointing to all gateways (A) provides no ordered failover. A Line Group (B) is for DN-level hunt, not gateway selection. A new Partition/CSS (C) controls access, not routing order.
