i have a problem in configuring IP RSVP

i already configure everything but when i make a call it drop even if i increase the bandwdth to 300 still the call not working

this is my configuration

interface Tunnel0
 description MPLS
 ip address 172.16.21.122 255.255.255.252
 tunnel source GigabitEthernet0/0
 tunnel destination 172.18.18.12
!
interface GigabitEthernet0/0
 Description "Wan"
 ip address dhcp
 duplex auto
 speed auto
!
interface GigabitEthernet0/1
 Description "Lan"
 ip address 192.168.63.254 255.255.255.0
 duplex auto
 speed auto
 ip rsvp bandwidth 3
!
dspfarm profile 1 mtp
 codec pass-through
 codec g729r8
 rsvp
 maximum sessions software 4
 associate application SCCP

After that i add the MTP and MRGroup and Assign it to MRList and assign it to the device pool
i configure location and configure that it will talk to other location with rsvp Mandatory
once i do that the call drop but even if i increase the rsv bandwidth in the GiG0/1 to 200 still call will not work

but if i remove the RSVP configuration in the CUCM then the call it work

Please tell me what ami missing

Hi

Can you try the below;-

1- MRGL

assign the MRGL direct to the phone , under phone setting then reset the phone.

2-Disable G711 under MTP , only use G729

dspfarm proofile 1 mtp

no codec g711ulaw.

exit

no sccp

sccp

3-Lets say we need to make 4 calls G729 which will be 256. So configure bandwidth to 256.

4- Last thing make under tunnel " ip rsvp bandwidth".

Thanks

please rate all useful information

Hello aysar

1- Did you configure bandwidth under location , system - location?.

2- Did you assign location to DP?.

3- Did you check that MTP is registered on CUCM?

Thanks

Thanks very much i just needed to assign the Bandwidth under the location and it work like a charm and i also configured the AAR and i low the RSVP on the interface GIG 0/0 which is the Wan interface and i receive network congestion rerouting and Obba the call went through PSTN

Thanks very Much

i have just a quistion i know it been a while but

when i configure RSVP no matter how big the number under ip rsvp bandwidth 1000 still the call drop isn't that should at least allow for 15 calls

but when i configure the AAR it aallow for re routing which is perfect
