This is one of the strong points of the ShoreTel architecture. Shoregear switches all keep a copy of the current configuration and know where the end points (i.e. This will setup a ping to port 5440 at the target device of 192.168.10.12 and the quotations are required! The comma 100 means, send 100 packets in this test. To do this you will need to run the ipbxctl security command from a ShoreTel server first, then telnet into the device and run your test. Unlike Ping which you can run from your local computer to a destination ip address, you will need to telenet or Ssh into a ShoreGear switch to run lsp_ping. In the example Bob can Ping Carol, so why is the BOX red? The answer might be to run an lsp-ping command. This ping makes it possible to test network connectivity at the higher L4, transport level by enabling you to Ping with a port number. ShoreTel has a proprietary protocol named lsp_ping. What happens if the Ping is succesful? You do your Ping test and you get an excellent reply and the network is not broken at the Layer 3 level. The more challenging problem is more perplexing. Now if the test fails, the next step is to figure out where the network connection is broken. You will ping from the source IP address of one site, to the destination ip address of the other sites device.
The network engineer will undoubtedly do a Ping test. Why is this happening? Lets Ping and find out! The RED box at the intersection of two lines helps you visualize connectivity or lack of connectivity. This is very not good! Sites can not communicate and calls are failing all over the place! For example the trunk group that terminates on HQ SGT1K-03 (Line 13), for example will not be able to complete an incoming call to a user on the user switch Central Time Zone (Line2). How do you visualize this in ShoreTel? You go to the second screen and by clicking on Connectivity and you see the famous ShoreTel Christmas Tree! Carol can also connect with the Ted and Alice sites. Bob however can connect with the Ted and Alice Sites. You quickly scan the screen for RED! (That is what is so simple about alarms: Green is good, Yellow means something needs attention and Red is bad)! In this example the site known as Carol can not connect with the the Bob site. ShoreTel administrators learn very quickly that the first place you go when someone complains about the phone system is the ShoreWare Director portal to the “Quick Look” section. It can be used to determine latency and jitter and is a very quick, effective and easy to execute network test tool. Ping is generally a knee jerk reaction for a network engineer! It will establish and demonstrate connectivity between network devices. Ping target Īs an example : ping -n 5 -l 1500 the ping command is used to ping the hostname The -n option tells the ping command to send 5 ICMP Echo Requests instead of the default of 4 and the -l option sets the packet size for each request to 1500 bytes instead of the default of 32 bytes. Some even know that you can add options to ping to set packet size and repetitions, but at the end of the day, Ping is a level three ICMP command. Audio still cut off at the 15:36 mark.Most network folks are comfortable with a standard Ping command. In the Siperator Under sip services, interoperability, I tried changing the signaling order of reinvites from send re-invites all the way directly to send response before re-invites are forwarded.Īll that did was keep the far end from dropping immediately. Nothing gets sent to the siperator and as a result the siperator sends a 408 request timeout to the service provider, dropping the link. The shoregear switch then responds to the IP set with a 507 status : 409 server internal error - re-invite inside a re-invite. Packet captures indicate a 15 minute keep alive reinvite being sent to the siperator, to the shoregear switch, to the IP set then the IP set responds with an invite of it's own. Have not tested calls directly answered by a 480G set. In calls answered by the auto attendant and routed to their destination do not drop at the 15 minute mark. Pick up a polyccom conference phone (registered to the shoretel system) dial a telephone number and have a call continue past the 20 minute mark. I usually abandon the call at the 20 min mark. Pick up a Shoretel IP480G telephone set, Dial a telephone number, place the call on hold then unhold, the call continues past the 15:36 mark.
At the 15:36 mark, the far end drops but the trunk test tool and communicator (I have not looked at the icon on the telephone set yet) show the call still in progress. Pick up a shoretel IP480G set and dial a telephone number. Outgoing calls placed on SIP trunks disconnect at fifteen minutes and thirty six seconds.
