Problem in VoIP - SIP with router D-Link

I want establish communication with ( VoIP-SIP) ,the élements of my Network are PABX BCM50, Router D-Link and Hypermédia, when I call à GSM from the phone connected to the BCM, the person with GSM hear me but idon't hear him.

Please help me,

Thank you.

SOURCE: Won't allow connection to router

Since each of these devices is rated for 1000Mb/s, everything should be compatible. Make sure the NIC driver is up-to-date on your computer....and use automatic settings for speed and duplex wherever you have the option of setting it. The only other thing I can think of is to try a "crossover" cable between the router and switch...although this function is usually handled automatically in most modern interfaces.

SOURCE: Layer3

http://en.wikipedia.org/wiki/OSI_model

Layer3 is the Network Layer of the OSI Model, IP operates at Network Layer, OSI Model comprises of 7 layers, Application, Presentation, Session, Transport, Network, Datalink, Physical layers.

It is a model to follow when you are building Operating systems, applications to be used on the internet or compatibility with others.

Hope this helps

SOURCE: connecting xbox live to my d link 1005d

Is the PC's connected to the D-Link able to browse the Internet? Sometimes the MAC Address will bind to certain IP's and must be cleared out when the Router is replaced. Please unplug the power to the router, X-Box and Cable or DSL modem. 1st plug in the power to the DSL/Cable modem until the "Ready" light comes on. 2nd plug in the power to the D-Link Router, wait 30 seconds then plug in the X-Box, power on and test. If a computer plugged into the D-Link will browse Internet then this is the solution to your problem.

SOURCE: Layer3

Which model are you talking about ? I have included both


Here is the OSI model
Layer 1 = physical medium & signal on the wire (physical)
Layer 2 = MAC Address and SNAP (ATM) (data link)
Layer 3 = IP Addressing V4 V6 (network)
Layer 4 = TCP/UDP (RTP, RTSP) (transport)
Layer 5 = Duplexing Half or full (Session)
Layer 6 = HTTP, FTP, SNMP (presentation)
Layer 7 = Web browser, FTP Client, (application)

TCP Model:
Layer 1 = physical medium & signal on the wire (physical) (Hub and reapeter)

Layer 2 = MAC Address and SNAP (ATM) (data) (Switches and bridges)

Layer 3 = IP Addressing V4 V6,
Layer 4 = TCP/UDP (RTP, RTSP) (Internetwork) (Firewall, IPSEC) Routers

(This function is split between 4&5) Duplexing Half or full

Layer 5 = , HTTP, FTP, SNMP, Web browser, FTP Client, (application) (programs)


I hope this helps,

Thank you,

Can i connect a netgear JFS524 directly to acable modem


Connecting your switch directly to the modem instead of to a router is not a recommended practice. A router has Network Address Translation (NAT) and Stateful Packet Inspection (SPI) which are important built-in security features ( i.e. a firewall). The router also gives priority to certain types of data so that VOIP phone calls ((internet phone service) and streaming media (Netflix, YouTube, etc.) are not interrupted or degraded. As far as I know your switch lacks these features which may then cause problems for some users when the network is busy.

Need driver and firmware for LinkSys RTP 300, or how to set it up for simple home network with interneton the PC and laptop as the 2nd computer.


No drivers are required since there is no actual installation to to the computer. Connect the ISP modem to to the main LAN network port. Then use any available port to access network. 1.Power 2.Main drop. 3.Network. That's it!

If the router is used, you may want to reset custom settings by, holding in the reset pin till it cycles.

Advance setup.

I have a D-link DGS-1005G. I have two computers connected and a printer. The D-Link is also connected via LAN. I can obtain internet connection to each computer with wireless and the printer will not...


Hi, you have to set up your printer as a device that can be communicated in your LAN by the two PCs.

To set up your printer properly in the LAN, you need to assign a fixed IP to this printer such that whenever it is switch on again, both PC still communicate to this printer without changing the new IP assigned to this printer.

You need to set up this fixed IP properly in your DLink router. For guidance please check this in your user manual of the Dlink. Please let me know any problem you may have again in future.

Can you please send me the step by step configuration using d-link


To be able to most accurately answer your question, I would need more information, but I can tell you what I did with my D-link DIR-655 router. 1. With my computer and router turned off, I plugged the ethernet cable from my (cable) modem to the input on the router. 2. I then plugged an ethernet cable from the computer to one of the 4 ports on the back of my router. 3. Once the cables were connected, I then powered on the router by plugging in the power supply. 4. Then I powered on my computer. You should then be able to connect to the internet using a wired connection. At this point you'd be able to also connect to the internet wirelessly by selecting the network named dlink. 5. To configure the router to work for VOIP, gaming or secured wireless networking, you can navigate your browser to the admin configuration page on the internet.

I have a 8 port ethernet switch DES-1108 how do i connect it to a DSL cable modem and the 3 computers i have . do i need to use the router still. or what


If the computers only need to communicate with each other then you do not need a router.
Each of the computers must have the same Network name (workgroup) and have the same IP address range. If you have a fixed IP address on each of the computers the IP address range should be the same - for example 192.168.3.xxx (xxx being a number unique to each of the computers, BUT the first 3 group of numbers (IP address range) MUST be the same on all the computers.
If the computers need Internet access then a router is required and if there is insufficient LAN ports on the router then you need to add a network hub connect the router to tht hub and connect the computers to this hub. You would need to configure the computers to obtail an IP address automatically, the router will issue IP address to the computers automatically.
I would not recommend using the Ethernet switch with the router as it would require a more complex configuration.

I have a tenor dx 6120 connects to an omnipcx office but i cannot make a voip call with it although I 've configured it to make sip call


Unfortunately, there are any number of reasons this could be a problem. The only sure way to tell what's going on is to look at the SIP traffic directly.

If you are up for it, here are the steps you'll have to take:

1. Download and install Wireshark(it's free) from www.wireshark.org

2. Install wireshark on a PC and connect it to the same switch as the Tenor,

3. Configure the switch to use the PC port as a monitor port for the port the tenor is connected to; you need a managed switch for this.

4. Start a capture with Wireshark for the appropriate interface. You'll probably see a shocking amount of traffic on your network all of a sudden. Don't worry, we're going to filter out the stuff that doesn't matter and it will be much more manageable.

5. Click the Telephony tab and select "VOIP calls". Try to make a call or two and see if this provides any useful info.

6. If #5 didn't help, go back to Telephony and select the "SIP" filter. This will provide more basic info on what is going on with the Tenor by showing every SIP packet. If you don't know anything about SIP it can be pretty hard to read though - you may need to post results here and let us take a look.
