It doesn't have any knowledge of whether or not the formats or allowed or disallowed - just that you have a list of formats. What's more, this string is already enclosed in paranthesis, so there's no way to individually put a "!" in front of each disallowed codec. So the allow/disallow values can look identical:
allow=ulaw,alaw => (ulaw|alaw)
disallow=ulaw,alaw => (ulaw|alaw)
This puts the "!" in front so that the dialplan can tell that the entire list is disallowed:
disallow=ulaw,alaw => !(ulaw|alaw)

While I was looking at it, I thought that - other than the name of the endpoint associated with the channel - endpoint details really shouldn't come from the CHANNEL function. They should come from something else. Hence, the PJSIP_ENDPOINT function.
This function lets you query any property configured on an endpoint, for any endpoint, from the dialplan. Assuming the CHANNEL function gets applied to chan_pjsip, this would let you extract information about a channel's endpoint - or whatever endpoint they're going to go talk to.
This has some obvious implications in knowing what's about to happen before you go Dial some endpoint.
As an aside, I think this patch also shows (to a small extent) the usefulness of both Sorcery as well as XML configuration information. More lines of code are spent on sanitizing input than anything else.</pre>
