1. Check Access list match or not
show access list "number"  > 看match到的ACL 數是否增加，判斷ACL是否生效

例：sh access-lists 299
    Extended IP access list 299
    10 permit ip host 172.20.20.105 any (15703 matches)
    20 permit ip host 172.20.20.43 any (2963014 matches)
    30 permit ip host 172.20.20.90 any (6871012 matches)

2. Check Frame Relay status

show frame-relay pvc
show frame-relay map

3. Check Voice Router status
撥出:

show call active(history) voice brief | include "number"  >查看正在撥出電話分機資訊

36BA : 828955 -2023620384ms.828626 +3570 +24770 pid:11 Originate 12345

show call active(history) voice brief id "number id"  >查看撥出對方之詳細資訊，判斷是否有撥出

36BA : 828954 -2023620394ms.828625 +3580 +24800 pid:0 Answer 53
dur 00:00:21 tx:1041/20753 rx:719/14380 10  (normal call clearing (16))
IP 10.1.2.229:17582 SRTP: off rtt:6ms pl:10170/280ms lost:-1/0/0

0ms g729r8 TextRelay: off

36BA : 828955 -2023620384ms.828626 +3570 +24770 pid:11 Originate 12345
dur 00:00:21 tx:718/20104 rx:2082/41506 10  (normal call clearing (16))
Tele 1/0:1 (828955) [1/0.2] tx:18440/16390/0ms g729r8 noise:-75dBm
acom:45dBm

撥入：
開啟debug mode-
debug voice ccapi inout ==>開voice debug mode
undebug all ==>關debug mode

terminal monitor ==>開terminial monitor ，即時查看進線Log，側錄Log用
terminal no monitor==>關terminial monitor

4. Voice Router 分機設定

dial-peer voice 99000 voip  >>對應pid
例：292C : 428337 17653222410ms.428330 +8550 +82960 pid:89000 Answer 0966250544 destination-pattern 99.... >>當撥出號碼為99....(後面幾個.與分機號碼設定要一致，三個.跟四個.是有差異，要非常注意)
 session target ipv4:10.1.2.59 >>Router next hop到目地端的Voice Router IP，IP設錯就無法撥通電話
 ip qos dscp cs5 media
!
num-exp 11... 1111...  >> 轉碼使用，表示當使用者撥11345，經過Router送給目地端的Router會收到1111345
num-exp 12... 1212...
num-exp 27... 2727...
num-exp 28... 2828...
