I will be connecting a couple of 1861's...and also some VG224's to 2821 and 3825 routers. If i am plugging analog phones into the FXS ports on the 1861's and VG224's do they automatically mark the packets coming from the FXS interfaces as voice packets (EF) or do i need to do this manually?...if so i am not sure how i would because the interfaces are voice ports which i havent assigned ip addresses to...I would imagine that if i was using an IP phone instead of analogue i would be able to set the QOS on the phone itself so as to get end to end packet marking, but how does this happen with an analogue phone that has no QOS or IP capabilities?
Thanks and regards,

it sounds i cklicked twice on the post :)
anyway
just one note
the above policy should be apllied on the interface of the switch or router that connected to the VG
and add the following line to the
ip access-list extended call-signaling
permit tcp any any range 2000 2002
and good luck

if u have voip dial peer point to ur CCM then u can make the marking through this dial peer
for example
dial-peer voice 1 voip
distination-patren [ccm ip]
codec g711ulaw
no vad
ip qos dscp ef media
ip qos dscp cs3 signaling
however what i sugest u is because u have the VG will be on one vlan which is the vlan that belongs to voice lets say vlan 20
so just creat an ACL that match all traffic coming fron that vlan for example the range will be like 10.1.1.0/24
so make somthing not exactly but similer to :
ip access-list extended call-signaling
permit tcp any any range 1719 1720
permit tcp any any range 2428
ip access-list extended VVLAN
permit udp 10.1.1.0 0.0.0.255 any range 16384 32767
class-map match-all VVLAN-VOICE
match access-group VVLAN
class VVLAN-CALL-SIGNALING
match access-group call-signaling
policy-map VG-marking
class VVLAN-VOICE
set ip dscp 46
class VVLAN-CALL-SIGNALING
set ip dscp 24
here the interface gos from the VG to the lan
interface [port number]
service-policy input VG-marking
u can chose from the above to ways which one suit u
good luck
