Yes you do need to fire up QoS on all links, sounds like serialization delay may be killing you on the lower circuits, which means you need to turn on LFI as well.

Below is the setup that I am trying to do :- CiscoCallManager--------->LAN SWITCHLAN SWITCH | | 2 MBPS | | | | 64 K | 64K | | | | | Cisco ATA Location X Location Y Cisco ATA (2 Phones) With ATA With ATA (2 Phones) (2 Phones) (2 Phones) Setup :- 1) Cisco callmanager resides at Headquarters. (CCM version 3.1(3a) ) 2) The link between HO & RO is 2 Mbps (Voice + Data ) 3) The link from HO to its nearby location is 64k & similarly the link between RO & its nearby location is 64K (Voice + Data). However there are many locations & are connected to HO & RO via Channelised E1 & 64K each. 4) All the locations are having Cisco ATA's where we have option for connection 2 analog phones (FXS ports) 5) In Cisco callmanager following things are configured - (a) Location for every place - for call admission control with 48K as BW (b) region for every location (c) Pool for every location. 6) The codec used between all the WAN locations is G.729 except the locations HO & RO. Between HO & RO where there is 2Mbps the CODEC used is G.711 (Here if we try to enable G.729 as the codec then the voice calls are not going thru.) Problem - The voice calls are going properly w/o any problem between location X & Location Y with a good audio quality.The voice calls are also going fine between HO & RO on 2Mbps link. But the voice quality between Location HO & its nearby location X is very bad (Both Ways) . Similarly the Voice quality between RO & its nearby location is again very bad (Both ways). Can anybody tell me why am I getting this issue only on 64K link. My requirement is that atleast one voice call should go thru at any given point of time along with data. What settings do I need to check from the Callmanager side ?? & from the locations side ?? Do I need to implement QOS between all the WAN locations ??
