hi All,

I am trying to connect HQ and SB with a 384 k frame relay
 PVC.Enable FRF.12 link fragmentation and interleave on the Frame Relay 
connections to
fragment large data packets and interleave voice packets to minimize delays. 
Max delay between fragments should be
set at 10 ms . Also provision RTP header compression.

Configure LLQ between HQ and SB to ensure voice bearer traffic gets priority 
queue treatment & voice signalling
is guaranteed for 16kbps. Configure the priority queue accomodates
up to 4 G729 calls between HQ and SB.

Lastly, assume all bearer voice traffic has been marked with
traffic CS3.


Here are the steps I am following ...
-------------------------------------------------------------

1) Going to serial interface connecting from HQ to SB  on the HQ router 
and changing the BW to 384

R1(conf)#int ser0/1/0.X
R1(config-subif)#bandwidth 384


2) Then apply "auto qos voip trust" under the interface

R1(conf)#int ser0/1/0.X point-to-point
        #frame-relay interface-dlci 201
        #auto qos voip trust


3) Then after the auto qos trust is applied . I remove
no match ip dscp af31


4) add ...priority 47
and bandwidth 16

5) Then remove "no frame-relay ip rtp header-compression"


6) Add the following...


map-class frame-relay AutoQoS-FR-Se0/1/0-201
frame-relay cir 364800
frame-relay bc 3648
frame-relay be 0
frame-relay mincir 364800
frame-relay fragment 480
service-policy output AutoQoS-Policy-Trust



7) add "compress ip header rtp"



8) I then move to SB router and do the same steps ( 1-7) on the interface 
connecting to HQ



9) After this I create a class map on HQ router with Site C


map-class frame-relay 2MBPS
frame-relay cir 2048000
frame-relay bc 20480
frame-relay be 0
frame-relay mincir 2048000


interface Serial0/1/0.2 point-to-point
description *** FR Connected to BR2 ***
frame-relay interface-dlci 202
class 2MBPS


Problem:
-------------------------

1)
 My phones in Site C unregister and don't register back after the above 
configuration.  Looks like QOS breaks phone registration


2) The calls between sites appear to be slightly delayed.

3) Audio on the phones seems to be watery.



Questions :
------------------------ 

1) What is wrong with the above config?

2) Is there an easier and safer way for achieving the task?

3) How can the above task be achieved without causing problems?
