[Asterisk-Users] sip.conf not paying attention to allow/disallow

[Race Vanderdecken]

This is correct.

Out going calls default to the global capability.

Then some CODECS are added or subtracted.

But,

	The CODECS are not in a list the way you would think. They are
in a bit field.

	So the obvious list of 

		1. alaw
		2. ulaw	
		3. gsm

	where you would think that Asterisk would first try alaw, then
ulaw, then gsm. 
	This NOT what happens.

(Aside : The capabilities are blended into a bit field, "010110110". The
first bit that works is the winner.)

	But when you call out the default "globals" are dropped in to
the capablitiles bitfield with the "privates" only being used if the
jointCapabilites has not been previously set. Asterisk does not seem to
check the private CODECS going out the door. But that is only a short
quick look at the code.

The SIP channel is good, but not great. It is not a bug so much as an
unexpanded feature.

My advise, create a database.

It's not a bug. You are setting global parameters. When you do that, it 
overrides the peer settings. Try setting for each individual peer. If
you 
have many peers (100 or more), use a database solution such as RealTime
or a 
script to build your sip.conf (one is included with the cvs).
