How to check the current configuration?
For more information concerning the way to configure the call admission control, please refer to
Administration Guide: Call Admission Control v2.
The configuration loaded by the communication server can be checked via the asterisk console:
Navigate to: SOP > Shell > Diagnostics > Telephony > Asterisk Console
To check the list of sites do the following commands:
00000072*CLI> cac show sites
Name Networks Default route
site A 2 MLE00001
site C 1 MLE00003
site B 1 MLE00002
You can check the number of networks in the site and the routes available.
To check the list of networks, do the following command:
00000072*CLI> cac show networks
NetworkID Netmask Site
172.16.34.32 255.255.255.252 site A
172.16.34.248 255.255.255.252 site A
172.16.32.72 255.255.255.252 site C
172.16.34.36 255.255.255.252 site B
To check the media links, use the following commands:
00000072*CLI> cac show medialinks
Name Maximum Current
MLE00001 1 0
MLE00002 1 0
MLE00003 4 0
3 medialinks
The Communication Server tracks the media streams and based on the IP address of the different peers and the inter-site routing, the media links usage will be updated.
Navigate to: SOP > Shell > Diagnostics > Telephony > Asterisk Console
To check the list of channels do the following command:
00000072*CLI> show channels
Channel Location State Application(Data)
SIP/SDP40001-0000001 s@macro-Action_CallD Up Dial(SIP/SDG30001,35,o)
SIP/SDG30001-0000001 (None) Up AppDial((Outgoing Line))
2 active channels
1 active call
14 calls processed
To check the IP address of the SIP peers, do the following commands:
00000072*CLI> sip show peers like SDP40001
Name/username Host Dyn Forcerport ACL Port Status
SDP40001/SDP40001 172.16.34.33 D N 5060 Unmonitored
1 sip peers [Monitored: 0 online, 0 offline Unmonitored: 1 online, 0 offline]
00000072*CLI> sip show peers like SDG30001
Name/username Host Dyn Forcerport ACL Port Status
SDG30001/SDG30001 172.16.34.39 D N 5060 OK (32 ms)
1 sip peers [Monitored: 1 online, 0 offline Unmonitored: 0 online, 0 offline]
To check the list of mediastreams tracked by the Communication Server, do the following command:
00000072*CLI> cac show streams
Name Local Remote Local link Remote Link Direct
SIP/SDG30001-00000019 172.16.34.39:5004 (site B) 172.16.34.33:16398 (site A) MLE00002 MLE00001 Yes
SIP/SDP40001-00000018 172.16.34.33:16398 (site A) 172.16.34.39:5004 (site B) MLE00001 MLE00002 Yes
2 media streams
The commands will list all the detected streams:
- The first column show the name of the associated channel
- The column 'Local' shows the IP address of the SIP peer
- The 'Remote' column shows the IP address to which the SIP peer is echanging the RTP packet. It can be the IP address of the SOP of the IP address of the remote peer in of peer to peer RTP packet exchange
- Next to the IP address, the site in whic the IP address is located is provided
- After the IP addresses, the list of medialinks over which the RTP packet are going is provided
- The last column indicates whether RTP packets are directly exchanged between the two SIP peers in conversation. This is the case when using re-invite or direct rtp.
To check the current medialink consumption, use the following command:
00000072*CLI> cac show medialinks
Name Maximum Current
MLE00001 1 1
MLE00002 1 1
MLE00003 4 2
3 medialinks
The list of configured medialinks are provided together with some dynamic counters:
- The column 'Maximum' provides the maximum number of allowed streams
- The column 'Current' provides the current medialink consumption
For more details, use:
00000072*CLI> cac show medialinks verbose
Name Maximum Current Local Remote
MLE00001 1 1 0 2
MLE00003 1 1 0 2
MLE00002 4 2 2 0
3 medialinks
- The column 'Local' provides the number of streams going through the SOP (Local Bridge)
- The column 'Remote' provides the number of streams with direct media exchange between two peers (Remote Bridge)
You can see that the Current medialink consumption is equal to the Local usage plus half the Remote usage (C = L + R/2)
