> The problem is that one such code chunk was forgotten and is still here in the "else if (!name && sin)" block, duplicating what is already done in the for() line.
> The end result is that instead of going through the linked list of MGCP gateways one by one, when a static unnamed MGCP GW is encountered in the list, the next GW is skipped.
