I am encountering delays when making any calls using VOIP. I understand that there is always a delay using VOIP but not as much. I've done a bandwidth test on my network and everything seems to be Ok, we have 4 T1s with 55 Reps using it. There is nothing choking up the network.

View 1 Replies View RelatedA couple of users on my network complain about timeouts. They access the same server which runs a SQL server. People from outside world can access it without a problem but internally it keeps timing out. I have also noticed that VoIP phones have a delay internally. So if i pickup my phone and dial an extension the other person can't hear me sometimes but i can hear him.
I have experienced the VoIP problem but have never had any time outs on my machine. I tried packet capture on a couple of computers but i cant see anything out of the ordinary. Alot of ARP, some STP which i think shouldn't reach the machines, dropbox traffic etc.
I recently purchased a rvs 4000 wired linksys router for my business. Everything works great with the exception of my VOIP PBX server. I can receive a call and make a call one at a time. If a second line rings in and is picked up the first call and the second go dead air. I am sure that it is a security setting somewhere that I just can't seem to figure out. I sure would like to get some direction on this.

I just upgraded my DLink DIR655 to WDR4300. My VOIP service has worked for the last 5 years. But with WDR4300, I'm frequently experiencing dropped calls. The call will be cut off every 20 seconds or so. This is really a deal-killer.

View 1 Replies View RelatedI've got a strange problem with my internet connection. I have recently moved and brought my desktop with me. While I am able to connect to the internet in my new place, a weird problem arises: whenever I try to access a new webpage, there is a consistent 5-10 seconds delay before the page actually loads. After the initial delay however, the webpage will load quickly. This problem will repeat itself whenever I try to access a site that is not cached. I have tried switching ethernet cables/wireless adaptars and this problem persists. I have also tried scanning and cleaning my computer yet nothing works. Speedtest.net show that my ping, d/l and upload speed are all fine.
PS: Just to add some information, my new place comes with its own existing router (the building includes internet into its rent), and I am simply plugging an ethernet cable from my computer to it. In addition, my roomates and my laptop seem to be able to access the itnernet fine with this problem. Since this sounds a lot like a DNS problem, I have also tried using OpenDNS and that doesn't work either. In addition, the delay persists regardless whether I am trying to access a website via its domain name or numerical IP address.
i'm having some problems to configure.i have two sites, a primary site and the secundary site, in both sites every switches are layer two. I configured and activated the RSTP (802.1W) in every switch, but about every 30 minutes the topology change and happening a delay in network and loss some ping (ICMP).

View 3 Replies View RelatedI have Cisco Catalyst 6500 with IOS Version 12.2(17r)SX5I need real-time monitornig of failed interface, to shut it administratively down and after 5 minutes "no shutdown" it.I think is good idea to use Cisco EEM for this task.My algorithm is below:
1. EEM script is looking for event about failed interface.
2. EEM script is shutting interface down.
3. EEM script is waiting 5 minutes.
4. EEM script is enabling interface.
I know how to configure EEM for steps 1, 2 and 4, but step 3 I do not.
Is there a device, which is able to produce a time delay on fiber optical link? I mean for example if one would like to reduce the power level of an optical signal, he could use simple air-gap optical attenuator on optical link. However, has somebody seen a device, which is able to introduce a time delay on optical link?
View 6 Replies View RelatedAny good way to force a serial link to delay packets to simulate a hi latency WAN link? Found this command so far:
Router(config-if)# transmitter-delay hdlc-flags
I can dial the speed up/down via clock rate all good but I need to also simulate latency. This is for simulating a WAN bonding scenario so I was going to aggregate a 10M ethernet port with a 2M serial and a 512k serial. But I need to also ensure varying latency.
I noted that my router (Linksys3200) has delays or lag on the average of 5 to 10 seconds apart, but random, while playing on line games. While continuously monitoring delays (ping) with a program called Ping Plotter, it ranges from 25ms to 65ms. When not gaming, just surfing the net, the ping is zero and once in a great while a 5ms or 6ms spike may occur.
Am I looking at a malfunction in the router or the computer? or Is this normal?
I have a fairly new HP Proliant server that serves as a fileserver, among other things. I've tried serveral operative systems in order to find the one that suits my server-needs best and ended up with Windows 2003 Server.When browsing shares on my server over local network, there is a slight delay on approximately half a second every time I navigate. It's not a huge problem but it's enough to be annoying.However, there was no problem when I tried Debian 6 with Samba. So logic would suggest the problem is somewhere in a setting or something like that. But which setting? [code]

View 3 Replies View RelatedActually i have problem with my connection and i would like to find that problem. i have 3 sites(1,2,3) connected together through fiber multi mode cable. The site 1 having the control room, the maximum distance between site (1 and 3) is 1.8 Km, the other distance(1 and 2) is 1.2 km and i already used 3750X switch and GIBIC GLC-FE 100Fx with support MM cable up to 2 KM.
i have in site (2 and 3) 10 cctv 3 mega pixel cameras and i check for the bandwidth is less than 100Mbps when i connected the 2 switches(2 and 3)to the switch in the site 1 there is a delay i thought maybe because of the bandwidth so i tried to connect only 1 camera but the same problem(delay). i did not make any configuration for the switches.
I start to use the CM. I received a request to block a number,I need to block the call only on the Call Manager or also on the Gateway that I have?
Can I get a modem that calls using analog and once it reaches my ISP it converts to 64K?
View 1 Replies View RelatedI have a wierd "2 second delay" issue with audio generation on a SRP527w.When in a call, with myself on both ends of the setup DECTphone - FXSport on SRP527w - VOIPprovider <> PSTN/GSM - Mobile I can hear my voice on the mobile immediately, as expected. However, the same words i speak (having both the DECT and the Mobile at my ears), are heared on the DECT with 2 seconds delay. Trust me when I say that this is the base for a poor rated telephone call and misunderstandings therein.
This issue is the same when calling to other mobiles and even land-lines, both in being called and being the calling party... Every time the voice from the other side is heard "delayed" on the DECT. Testing the DECT on a normal non-voip connection results in a normal conversation, as far as this is possible with me talking to myself I do have a separate CBR pvc for the voice on the SRP and to investigate the issue I've put the SIP user on a soft client, using a UBR pvc on the same SRP, both pvc's do use the same provider but diverend gateways. And with the UBR + softphone i do not have this "2sec delay" issue.
So, ruffly said this seems to locate the issue in the SIP>FXS DSP, with specific only the digital>analog decoding/generation (not with the analog>digital encoding, as i hear myself normally on the mobile, with no/normal msecs delay).

View 6 Replies View RelatedWe have 2 h323 IP phones (non cisco) that connect to an IP PBX via a VPN connection using PIX 5505's at each end. The VPN seems to work fine and the phones can be used normally with good call quality, display, status...The problem is that when talking on the phones for any extended period of time, the phone reboots, drops the call and then restarts automatically. This problem usually happens on phone calls lasting 20 minutes or more but has happened on calls as short as 15 minutes. I have also made calls which have gone 45 minutes before the reboot. I have removed everything from the network hosting the remote IP phones except for a single phone and the problem still occurs. It is not a POE Issue as the phones can use a power brick and it still happens. The same phones work perfectly on-site when not using the VPN.Someone has mentioned that I should adjust the UDP Timout Timers of the VPN. I don't see any UDP timers and am at a complete loss on what is causing this. The data traffic does not seem to get dropped when connected accross the VPN for hours at a time.

View 4 Replies View RelatedAs stated in the attached picture, my company has a remote office which its PBX was connected to the main PBX via a pair of leased lines and a pair of E1/HDSL converters. (The distance is about 2 kilometers, so the E1 was converted to HDSL and then back to E1 at the remote site)
Now, IP network is developed between two sites.We want to transfer the calls via a pair of 2811 Routers, both equipped with VWIC2-1MFT-T1/E1, as the second part of the picture. I tried to find an straightforward document, but I was unsuccessful.What configurations should be made at both ends to transfer the calls to/from the remote site ?
I have programmed two E1 ports on Cisco 2811, one for E1-PRI and other for CAS. My running-config is as below
controller E1 0/0/0
framing NO-CRC4
clock source internal
ds0-group 1 timeslots 1-15,17-30 type r2-digital dtmf dnis
[code]....
I have made 4 as trunk group access on the PBX for E1-PRI and 8 as trunk group access for E1-CAS.I am able to dial 4-1-6261 to place calls on telephone 6261 from 6000(outgoing and incoming over PRI). And I am able to dial 4-2-6261 to place calls on telephone 6261 from 6000(outgoing on PRI and incoming on CAS).But I am not able to dial out from my PBX extensions over the E1-CAS card using 8-1-xxxx or 8-2-xxxx. I have patched two PBXs back to back on their E1-CAS ports and am able to dial out using 8-xxxx. So this means the trunk group allocation on PBX is working fine. The show controller e1 0/0/0 is showing normal stats.When I do a show voice port 0/0/0:1 I see that one of the ds0 timeslots are being seized when I try to dial out on 8-x-xxxx but the Out Status column entry against the timeslot says clear_bak.When I am placing calls on PRI, I don't see any such indication against the timeslot being seized.Basically since I am able to dial in to my E1-CAS port, the line coding, framing, signaling(to some extent) must be right, or so I guess. But am not able to dial out.
About 2 years ago I bought my first laptop and the person I was with recommended my purchasing of a Belkin router. I bought the router, it worked great until this past summer when suddenly whenever somebody called my house phone, my connection was dropped. I was angry cause naturally I have those family members that want to call and talk on the phone with my mother for hours. Eventually I figured out I could work about the problem by hooking the Ethernet cord on my Westel directly to my laptop. Its a temporary fix though in my opinion because this requires me having to sit on the floor against my bed room door and this isn't comfortable, not to mention its also confining, I miss walking around the house with my laptop. Anyway this past weekend I decided to try buying a new Belking N300. This however didn't solve the problem, I still got my signal dropped whenever somebody called the house.
