Vic,
Loppback solution is only used as a workaround for invoking
Xcoder .Because calling from WAN to CME and then hitting AA would
not force CME to involve Xcoder.
So as a workaround we direct traffic to the loopback thus CME and
Xcoder and then AA will come to play.
Here is the proof.
GK with setup of G711 .
voice translation-rule 800
rule 1 /6667878/ //
voice translation-profile INCOMING_GK
translate called 1
dial-peer voice 800 voip
service aa
translation-profile incoming INCOMING_GK
incoming called-number 66678784444
dtmf-relay h245-alphanumeric
codec g711u
no vad
sh gatekeeper call
LocalCallID Age(secs) BW
138-14 13 128(Kbps)
Endpt(s): Alias E.164Addr
src EP: GK_TRUNK_1 2001
CallSignalAddr Port RASSignalAddr Port
140.0.0.1 3345 140.0.0.1 3245
Endpt(s): Alias E.164Addr
dst EP: CME 66678784444
CallSignalAddr Port RASSignalAddr Port
140.0.3.254 1720 140.0.3.254 49270
Opbviously ARQ does not comes into play adn we need just 128 for
G711 .
This way Service aa kicking in and work properly with out loopback
solution.

Vic,
Loopback solution is used as workaround to force CME to kick in the
Xcoder.As we can see with G711 ,there is no need for loopback
solution.
But BACD work properly ,we need at least 144k BW on GK, please
correct me if I'm wrong
128+16 for incoming calls from WAN

Ok- Jose got it right and this is what he was about to say (right?)
What is the difference between these two dial-peers on a gateway
registered
to GK?
Dial-peer voice 1 voip
destination-pattern 1...
session target ras
...
AND
Dial-peer voice 2 voip
destination-pattern 1...
session target ipv4:<Loopback0 IP Address>
...
When peer 1 is used an ARQ is sent to GK- it contains a bandwdidth
Request
and also a called # that needs resolving.
When peer 2 is used an ARQ is also sent to the GK since this is also
a VOIP
call on a gateway to a gatkeeper- it contains just a bandwidth request
though since we already did the resolution on the gateway (Lo0).
With the B-ACD call we all know that we are sending the call to
himself- the
Loopback interface- as a workaround to invoke "service aa" on the
inbound
voip dial-peer. However the gateway/gk is master/slave and no VOIP
call can
take place without GK's authorization. The gateway doesn't cross-
reference
locally configured ip addresses for every session target.
So even though the call is local GK still needs to accept the
bandwidth
request. And this is where "bandwidth total ... <128" would hurt you
since
the B-ACD call will always use g711ulaw and the INTRA-bandwidth
required is
going to be 128kbps.
Bandwidth total and B-ACD are dangerous for this reason.
