I dunno what a netlogic switch is. It doesn't matter. They send the invite in g711, we send a reinvite in t.38.
Look at frame 26, reinvite t.38. Now look at frame 30. They don't accept the codec. 488 not acceptable simply means a codec we are asking for (only t.38 in the re-invite) is not in their list. Either they do not support t.38 OR reinvite, or don't have the account configured properly. Up to the 488 there is nothing wrong with any of the transaction at all.
