Share on Facebook Share on Tweet

Mục tiêu thực hành:
- Cấu hình Dial-Peer trên CME1 đóng vai trò ITSP.
- Cấu hình Dial-Peer và Translation-Rule trên CME2.
- Thực hiện quá trình debug ccsip message trên CME2.
- Khảo sát lỗi debug ccsip message (forbidden) trên CME2.

Các bước triển khai:
Cấu hình Dial-Peer trên CME1 đóng vai trò ITSP.
- ITSP là nhà cung cấp dịch vụ SIP Trunk chẳng hạn như Viettel, VNPT, FTP, CMC.
dial-peer voice 1 voip
  destination-pattern 02838120120
  session protocol sipv2
  session target ipv4:10.0.1.2
  codec g711ulaw
  exit
dial-peer voice 2 voip
  destination-pattern 02838120130
  session protocol sipv2
  session target ipv4:10.0.1.2
  codec g711ulaw
  exit

Cấu hình Dial-Peer và Translation-Rule trên CME2.

- Cấu hình Dial-Peer và Translation-Rule tiếp nhận cuộc gọi tới 02838120120 và chuyển cuộc gọi cho 201.
voice service voip
  ip address trusted list
    ipv4 10.0.1.0 255.255.255.0
    exit
  exit

voice translation-rule 1
  rule 1 /02838120120/ /201/
  exit
voice translation-profile SipTrunk_Incoming
  translate called 1
  exit

voice class uri 120 sip
  host ipv4:10.0.1.1
  exit

dial-peer voice 1 voip
  incoming uri via 120
  session protocol sipv2
  codec g711ulaw
  translation-profile incoming SipTrunk_Incoming
  exit

Thực hiện quá trình debug ccsip message trên CME2.
- Thực hiện quá trình debug ccsip message trên CME2 khi IP Phone 101 thực hiện cuộc gọi tới 02838120120.
