Damn good question!! My thought is that the call on hold will be
'termiated' at the call control and not to the phone.
So while a call is on hold, the bandwidth will be near 0 to the phone.
Sent from my phone, apologies for any typos.

Pulling from the QoS SRND, the following configuration is only
supposed to allow the bandwidth for one voice call per switchport
VLAN. Obviously, based on the 128k, we're focused on G.711 calls
(so my next question will not apply to G.729).
I want to know if the following command would disable the ability to
have multiple calls (different lines) on the same phone. For
example: Phone A (with the policing command below) calls Phone B.
At this point, 128k of G.711 bandwidth is consumed. If Phone A puts
Phone B on hold and calls Phone C, would the call no go through due
to policing?
CAT2970(config-cmap)#policy-map IPPHONE+PC-BASIC
CAT2970(config-pmap)#class VVLAN-VOICE
CAT2970(config-pmap-c)# set ip dscp 46 ! DSCP EF (Voice)
CAT2970(config-pmap-c)# police 128000 8000 exceed-action drop
I guess what I am asking is what happens to the initial call when it
is placed on hold? Is the audio stream maintained between phones
(128k), thereby eliminating the ability to place another call?
