Subject: [OSL | CCIE_Voice] Bandwidth Update with GK

 

Hello,
 
I know in CM, to update bandwidth automatically when calls are going
through a gk, you'll have to modify the BRQ service parameter to true.
Does anyone know if there is an IOS command that does the same thing for
an H323 gateway?  Or if there is an IOS command that resets the
bandwidth allocation on a gk as soon as the call is terminated?
 
The reason being is that I experienced some codec selection issues with
calls from an H323 gateway to CM via a gk when i used a voice codec
class to prefer one codec type over another.  My prference in a codec
class is to use g711 first and g729 as a second choice.  The interzone
bandwidth is restricted to 144 (which is enough for 1 g711 and 1 g729
calls).  Sometime a call would use codec g711 first (which is correct),
and another time it would use codec g729 first (which is not preferred)
even though there is only one active call.
 
Any info is greately appreciated.  Thank you!
 
JD
