Sure. The best place for me to get patches (so they get disclaimed and all) is through bugs.digium.com. If you post them there, and open up a bug under libss7 I should get assigned to it and can apply your patches. For any other questions, you can of course email me directly as well, though if they're related to ss7, it might profit others on the list to see some of the correspondence.
