We have 2 CCM 3.2(3)sr3 and Unity with centralized design. There is a branch building near our main building. We have 2 T1 and 10 MB wireless between two building.
Thats how we configure on those two routes:
interface FastEthernet3/0
bandwidth 10000
ip address 192.168.254.49 255.255.255.248
no ip redirects
service-policy output voice-priority
duplex half
!
interface Ethernet0/1
bandwidth 10000
ip address 192.168.254.50 255.255.255.248
no ip redirects
service-policy output voice-priority
no ip mroute-cache
half-duplex
As you can see, I apply LLQ on interface. Also, wireless is running on half-duplex.
Now, sometimes user complaint about one-way-audio. Is that because of half-duplex???
We use EIGRP for those 2 T1 and wireless routing, I apply LLQ on 2 T1(serial) and wireless(ethernet). I saw most of Voice and Data traffic use wireless. However, I saw there are a little "signaling" traffic on serial interface, but no voice traffic on that serial interface.
router#sh policy-map interface serial 3/1:0
Serial3/1:0
Service-policy output: voice-priority
Class-map: voice (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: ip dscp ef
Queueing
Output Queue: Conversation 265
Bandwidth 33 (%) Max Threshold 64 (packets)
(pkts matched/bytes matched) 0/0
(depth/total drops/no-buffer drops) 0/0/0
Class-map: signaling (match-all)
5848 packets, 303112 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: ip dscp af31
Queueing
Output Queue: Conversation 266
Bandwidth 2 (%) Max Threshold 64 (packets)
(pkts matched/bytes matched) 9/472
(depth/total drops/no-buffer drops) 0/0/0
What I think of that, if user pick up handset, it will get dial tone(signaling) through serial interface (T1), and then voice traffice go to ethernet interface (wireless), will that cause one-way-audio???
I know my questions are confused and complicated.
Any suggestion and idea will be appreciated it.
Thanks in advance.
