Belkin Connection Lost During Phone Calls

Jan 30, 2013

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.

Cisco Wireless :: 7921 Wi-Fi Phone Calls Have No Audio With UC540 And AP541n

Mar 24, 2010

We have a new deployment where we have 5 total 7921G wifi phones connected via 2 AP541n access points, one connected to a ESW520p switch and then to the UC540 and the other connected directly to the UC540.  The wifi phones are intermittently giving no audio when calling each other, however, calls to the PSTN consistently do have 2 way audio.  Is this a security issue perhaps?  We are running the latest CCA software pack as this is a brand new deployment, also the AP's were upgraded to the latest firmware.

Cisco Routers :: RVS4000 QoS Configuration / Phone At Remote Site Drops Calls

Aug 22, 2011

We have an RVS4000 router at two ends of a VPN tunnel. The VPN tunnel is  working fine, however a phone at the remote site drops calls, even  though they sound clear and unblemished. I have set highest priority on  the port the phone is hooked up to at the remote site, and have set a  priority for upload traffic on both routers, but the phone stills drops  calls after 2 to 3 minutes.

Cisco VPN :: H323 Calls Dropping Over VPN?

Feb 9, 2011

We 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.

Cisco :: Transferring Calls Through The Network To A Legacy PBX?

May 1, 2011

As 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 ?

Cisco :: E1-CAS With E1 Controller On 2811 - No Outgoing Calls?

Nov 8, 2012

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


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.

Cisco :: Cucme Through Sip Trunk Not Receiving Calls From Landlines

Apr 9, 2013

I heard from customers calling into the office stating that they have experienced some issues with our prompts and the extension input, that it is not recognizing their input. Stating sometimes it does not work on their land line but once they call back on their cell phone it works. We in the office all had people from the outside call from a land line to our office to verify the issue but the calls went through. We are thinking that they may be dialing the wrong extensions.Has anyone had any issues with land lines having trouble calling in.I am running cucme connected to a sip trunk.

Cisco Firewall :: No Outgoing Calls To Outside After ASA5505 Installation

Dec 6, 2012

Have a asterix PBX running my system and I upgraded my security with a cisco ASA 5505. Now all the extensions are working including the remote once. Everything elase like internet.Other servers all working fine. Only problem is that when ever someone dials a landline number from an extension it does not go through.seems like the firewall is blocking it but I cannot figure out why or how. All the NAT and Access list is fine. Although I have no idea how to accept the SIP PROXY IP through the firewall and I am guessing that might be the problem.  There is no any other problem and I am 100% satisfied with the ASA5505 except this problem

Cisco WAN :: Debugging SIP Voice Calls On 3800 Router?

Oct 24, 2011

We're having some numbers ported over to us and we'd like to verify that we are in fact receiving all of the numbers at our SIP gateway.  Since we have been getting more and more activity on this router, I'm becoming more concerned about using certain debug's for fear that the router maxes out CPU and drops.
What the best debug command would give me this information with minimal impact on CPU?  In the past I've used 'debug ccapi inout' and a couple of others similar to that.  With so much activity though sometimes it bombs the router.  Also I am logging to the console directly, maybe there is a better method with less CPU impact.  I just don't want to have to go back and forth to look for stuff 50 times either if I write out to a file or something, it could work though I suppose.

Cisco WAN :: 3750 Improve Quality Of Skype Calls

Mar 28, 2012

I'm in charge of the IT of a dorm with 200 inhabitants. A lot of people complain about the bad quality of "skype-calls". Audio is delayed and video stucks. The actual speed of our internet connection should be fast enough so I guess it has something to do with the QOS setting. I checked it on our WLC 3750 and right now we use Silver (best effort). Could there be any improvement when I set it to Platinum?

Cisco 871 WAN - Router Drops H323 Calls After 1 Hour

Jun 20, 2011

I know the problem lies in the timeout for the default inspection rules. I cannot find where to change this.I have nat statements for 1 to 1 nat to my polycom and tandberg video devices. I have set the firewall for the ouside to in rules to inspect all. This allows the devices to communicate with public addresses, but the video calls drop after 1 hour. How do I change the settings so this does not happen. I have tried setting the rule to allow instead of inspect, but when I do this, I have no access at all. I just want to nat 1 to 1 and allow all traffic to the nated devices. I know this is not secure but it is the only way to allow h323 through to let the video conferencing devices work.

Cisco WAN :: 2911 / Multiple Video Conferencing Calls Takes Down T1 Connection

Jan 8, 2012

I have only seen this problem with several video conferences from one location.  Currently there is only one T1 connection from our HQ to remote location.  When two conference calls are set to use 256Kbps connection to come back to the main HQ, after an hour or so the T1 connection would drop.  What I mean about drop is that the route on the 2911 will disappear.  I have to wait about 10 minutes for the connection to come back up or I have to reboot the router for the connection to appear again.  There are no interface drops on the serial connections or ethernet connections.
HQ - 2911
Remote - 1821
 2911 running config:
 Current configuration : 3529 bytes
version 15.0

Cisco Routers :: Wag120n How ADSL Modem Handle Incoming Sip Calls

Feb 14, 2013

I have a Cisco wag120n adsl modem. I am setup with a SIP provider, so all my incoming and outgoing calls use SIP.So my question is, how does my ADSL modem handle incoming SIP calls,e.g the SIP call comes in and reaches my adsl modem. Then, how does the modem find the actual port that has my ATA adaptor (analog phone) or CME router attached  ? I know port forwarding would handle this, but I am not actually using any configured port forwarding rules.
