Headscratchers / Star Trek: Deep Space Nine S07E06 "Treachery, Faith and the Great River"

• The Jem'Hadar were ordered to jam all communication frequencies so that Odo could not contact them and let them know that he's on board. So how was Weyoun-6 able to contact Cardassia Prime in the end?
• Couldn’t Weyoun-6 have just pretended to kill himself? It not like he had to pull out a phaser and shoot himself; he pressed on his chin. It seems like that would be extremely easy to fake over a monitor - though this is assuming the Dominion doesn’t have some way of keeping track of such things remotely.
