The guy who helps you out, the phantom, places his summoning sign wherever he feels like, in an area that houses a boss. The phantom can have already killed the boss of the area and still be able to place summoning signs in that area. The most usual spots to place a summoning sign is by the closest bonfire, or by the boss fog. You and the summoner/phantom could also come to an agreement and have the phantom place it someplace secluded to reduce the chances of someone else summoning them. The summoning sign should eventually appear.
If you're having a hard time finding the summoning sign in the agreed spot, the host should quit the game for a minute or two and then try again, to refresh the IP storage. There's a certain limit. Silly mechanic.
