Cisco Routers :: Connect SPA122 For VOIP?

Jan 2, 2013

Here is my setup:
Cisco SPA122
Apple Airport Extreme Wireless Router
imac 2.8GHz Core 2 Duo
Thomson DCM475 Cable Modem
The imac is on a desk in the kitchen and is out main computer. The Cable modem, SPA122 and Airport Extreme are in the den just beside the kitchen.
I guess my first question is if the SPA122 has to ABSOLUTELY be attched to the computer? Right now I have it attached:
Cable to cable modem
Cable modem to Airport Extremet
Airport Extreme to SPA122
In this configuration, I can not access

Cisco Routers :: Connect SPA122 ATA To TP-Link TL-WDR3600?

Dec 7, 2012

I am trying to connect my SPA122 ATA to my new TP-Link TL-WDR3600 wireless router. This setup worked with my old router (NetGear WGR614) but I cannot seem to get it to work with the new router.

I am connected to the Internet through a Huawei MT130U cable modem with nominal 28MBS bandwidth. I have been told that the throughput of the router in the SPA122 would restrict that so I had connected it to my old WLAN router in the DMZ. This worked fine before but not with new router.

Cisco Routers :: VOIP Configuration - SRP547

Feb 6, 2012

I am unable to get any configuration parameters to work on my SRP547 for VOIP. ADSL2 works fine. Equipment replaces a (Arcadyan ARV4518PW) which worked ine albeit with significantly less features. Problems encountered due to the lack of equivalents for some parameters and an overabundance in the new unit which simply don't exist in the Arcadyan product.

Cisco Routers :: Voip With SRP547W And SPA303 Phones?

Oct 28, 2012

I have an SRP547W hooked up as the office router with the standard office phones connected via the telephone ports at the back of the unit using 2 SIP lines as well as the PSTN by dialling hash first. We have just added a new staff member and bought an SPA303 with the intention of connecting it through registered SIP lines on the SRP547W, and hopefully have the facility to use the PSTN line when the SIP lines are busy.
The problem is, it connects to VLAN100 and gets its IP address and initializes fine however no lines show as configured and it can't make or receive calls. What do I need to configure on the SPA303 to tell it to use the SRP547W as its SIP Server/Proxy (not sure of the terminology).

Cisco Routers :: RV042 Protocol Binding For SIP And RTP (VoIP)

Jun 26, 2012

I have a RV042 with a DSL (WAN1) and cable (WAN2) internet connection in Load Balance Mode. The DSL provider also provides internet telephony when registered via his line. When I disable the WAN2 port, my IP phone successully registers with the registration server of the DSL provider. I also defined protocol bindings for SIP (port 5060) and RTP (ports 5004 to 5020) to be bound to WAN1. My IP phone is set up to listen on only these ports. [code] With these protocol bindings in place when I re-enable WAN2, then after some time the phone reports "registration failed".Do I need to set something else apart from protocol binding to force the VoIP traffic to go via WAN1?

Cisco Routers :: RV082 - Settings To Improve VOIP

Feb 7, 2012

We have recently purchased an RV082 router for our company. I have successfully managed to establish a VPN connection through PPTP and through Quick VPN (IPSEC?)
When i am connected through PPTP my software SIP client has 0.5% packet loss which is totally acceptable. When i am connected through Quick VPN my software SIP client has a 50-70% packet loss.
i have done the following settings on the router: Bandwidth Management:

High Priority for upstream and downstream UDP 10001-20000 and UDP 5060-5080
Wan Connection settings: MTU: 1492 bytes
I would like to know if there are any other settings that will improve VOIP over Quick VPN since RV082 supports 100 connections compared to 5 for PPTP.

Cisco Routers :: Prioritize RTP Packets For VOIP Audio On RV180

Sep 26, 2012

Advanced networking but have managed to get our small office IP PBX running over a SIP Trunk. The only real problem we are having is choppy outgoing audio when there is other heavy outgoing traffic on the network.
My understanding is that I need to set some QoS parameters, which I have played with but it didn't seem to be useful. I mostly dealt with allocating bandwidth. I now think I need to somehow prioritize the outgoing RTP packets from our PBX (which runs on a PC on our LAN) to avoid the choppy audio. My research shows this can maybe be done with something called DSCP 46 and my router does support that -- how to exactly set the configuration.
Our router is a Cisco rv180w.

Cisco Routers :: WRVS4400N Stopped Working With VOIP Phone

Mar 1, 2013

I have the router for over two years, Present Firmware is V2.0.1.3, I have Polycom phone connected to the router using 8 x 8 VOIP service. The phone was working fine untill yesterday. 8 x 8 tech support suggested getting a different router. I have the same router at home and tried the same phone on my home router - it worked. So, the problem is not the phone but int he router. I tried to call Cisco tech support but found out that the warranty support expired and I need to buy a support plan. Called to buy the support, and gave up after an hours on hold. Left  message.

Routers / Switches :: Manage Static IPS In VOIP Setup?

Jul 21, 2011

I have VOIP and was provided a modem, a Tilgen Router (Vood 452_A). I also currently have a Linksys WRT54G router. I also have a home surveillance system with a DVR that can be accessed via the net. I am trying to allow the ports to open so that traffic can navigate down to the DVR.My IPs:My VOIP has provided me with 6 static IP addresses. For sake of this issue they are:, through .158My subnetmask is set to: Settings:

The Modem is connected to world. To the modem I have the Tilgen Router connected. The Tilgen is set with an ip of .153 and the subnetmask listed above. DHCP is turned on and has IP range set for .154-.158. It is set in Bridge Mode with NAT and Firewall turned off. To that I have the WRTG54G router connected and assigned the router an Static IP of .154.. The cable is going into the Linksys WAN port.From a computer connected to a LAN port on the WRT54G, I see my public IP as .154, currently my internal IP is so I believe I have to assign one of my Static IPs to this PC, however when I try to connect to the Linksys Router (.154) from the outside web, I am get a time out error. (also from a ping test.) My thoughts are to assign the Linksys to DHCP and use a range of .155-.158 to give each lan item a static IP. My question is will this work? Will each item in the network have its own IP and if I forward the port to the DVR that i needed, ie 80 for web client or 6100 for desktop client, will that forward through?Or do I set it to Router Mode and use the Tilgen to assign the ips.

On the Tilgen I also have an option for a DHCP relay or to turn off DHCP.

For clarification here is the setup chain
Broadband/DSL Line>>Tilgen Modem>>(LANPort1)Tilgen Router(LAN Port2)>>(WAN) Linksys(LANPort1)>>DVR/Computers
Found this walkthrough on setting the WRT54G into a Switch. If I did this, in theory the VOOD would assign those computers/dvr connected downstream via the WRT54G a static ip from my range set on the router. Then in theory I would not need to port forward port 80 since the DVR would be on its own public IP.?

Routers / Switches :: Office VOIP With Multiple Private Networks?

Jan 23, 2011

I'm going to move offices into a shared situation with 3 companies. Each company will want its own private network so there's no snooping between companies. I am planning on using VOIP for the phone system (Nextiva cloud based). Is it possible to set up the system so that each company has access to the VOIP system but yet remains sequestered in the their own network for everything else. I was hoping to do this with one data port at each workstation using Cisco SPA-303 phones. The way I understand this, is that the phone plugs in to the data port and you daisy chain the workstation off from each phone. Is this possible to do this while having the system I described? Another wrinkle is that I'd also like all the networks to be access shared printers.

Routers / Switches :: How To Connect Two Internet Routers To One LAN

Mar 8, 2011

How do i connect two internet routers to one IP address range?I currently have one broadband router connected on subnet, I have a second line which is a copper ethernet EFM 2Mb line connected using a Cisco 1800 router configured on subnet, no DHCP is configured on either router. the dhcp is provided by a windows 2003 server on our LAN which is also configured on the same LAN IP range. if i connect the Cisco router into the same switch as the broadband router my network devices stop working and dont respond.

If i check the broadband router it shows all the connections to it as having the same MAC address as the Cisco router?? if i disconnect the Cisco router everything returns back to normal and works perfectly.What I want to achieve is to be able to run both routers on the same LAN to provide internet access by configuring the pc's to route through a specific router. the DHCP I want to stay routed through my original broadband line. at the same time i want all pc's to access to the lan devices (ie. servers and printers) what the correct configuration would be for the two internet routers would be?

Cisco :: Configuring 2960 For VoIP?

Mar 26, 2012

We just purchased cisco 2960 for our VoIP needs and we are using polycom phones, and Phone and Computer will use same port. Since Polycom phones are capable working with CDP protocol and we are hoping to get another switch to expand VoIP network. I found easiest way of setting up each port is as following (from the cisco tutorial)

Switch#configure terminal
Switch(config)#mls qos
Switch(config)#interface fastethernet 0/1
Switch(config-if)#mls qos trust cos
Switch(config-if)#switchport voice vlan dot1p
Switch(config-if)#switchport voice vlan 10
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20

My first question,when we are using switchport voice vlan dot1p ,I thought we instruct the switch port to use 802.1P priority tagging for voice traffic and to use the default native VLAN (VLAN 0) to carry all traffic.Do I still need to create a Vlan 20 for data and Vlan 10 for voice ?

Secondly,same tutorial adds these commands as well,Do you think for our set up, using those commands are feasible ?

Switch(config-if)#switchport priority extend trust
Switch(config-if)#priority-queue out
Switch(config-if)#spanning-tree portfast
Switch(config-if)#spanning-tree bpduguard enable

Thirdly,when we get another switch and do the same configuration for the second switch, can I use any port on Switch 1 as uplink without doing any configuration ?

Cisco WAN :: SIP And VoIP Priority On 1921

Oct 25, 2012

I am fairly new to Cisco, but am trying to configure a 1921 router to give higher priority to SIP/VoIP traffic (Port 5060) than everything else.The connection is only 4Mb and is getting hit hard by video streaming, I don't want to block this, just make a lower priority.Any ideas where I am going wrong?My current config is as below.The IP addresses have been changed for security reasons, but in reality are both in the same range, i.e. are both external IPs, so I am not sure if this is causing the problem.  Do I need NAT for QoS to work?

Selecting A Router For VOIP?

Apr 6, 2012

Trying to select a router that will work well networking a computer with a nettalk duo, on a limited bandwidth connection: .3/3Mbps up/down. From what little I've been able to find on this, QoS bandwidth control seems critical, yet the list of recommended routers from Nettalk seems to favor routers that don't have this feature. On the other hand, the list apparently hasn't been updated in a year and a half.
