we have a Cisco 1801 at one of our remote sites that uses an ADSL line for it's primary connection and ISDN as backup. Despite no apparent problems with the ADSL line the ISDN is repeatedly dialling the internet every 2-3 mins during office hours and considerable expense to the customer.

Both of these ISDNs are up, this gives us 4 channels. Someone said they recieved a busy tone when they attempted to dial out. I looked over the system and seen there are two outbound pots dial-peers. Each dial-peer references one of the BRI ports. The preferences are the same on each dial-peer. I think what is happening is that the system is randomly selecting one of the dial-peers due to the preference, even if both channels of the BRI are in use. How does the system know if that port has both channels in use? I've not used ISDN before, so tried to enter the B-channel sub interface and the system (UC500) tells me I cannot do this. I was thinking about adding each channel into a trunk group and then referencing the trunk group in the dial-peer. I can obviously add both BRI's into one trunk group.

Here is what I connect the device. (I am in Japan)
ISDN Line (NTT east) >> DSU(NTT east INS Mate V30Slim with S/T port) >> Cisco 1812j(S/T)
On DSU setting I enable DSU and Disable Terminator.
First of I would like to test outbound call. Here is the config.
interface BRI0 ip address 192.168.92.2 255.255.255.0 encapsulation ppp dialer map ip 192.168.92.1 name Router1 broadcast 080********(Cell Phone Number) dialer-group 1 isdn switch-type ntt isdn point-to-point-setup ppp authentication chap ppp chap password 0 CISCO ip route 10.92.0.128 255.255.255.248 BRI0 192.168.92.1
Then I test by ping with #debug dialer. #ping 10.92.0.129
And I could not receive a call by my cell phone landline either.
Here is the debug.

I have configured Cisco 2811 and 3825 routers to connect the main and remote sites as per the attached topology. At the main site, the Cisco 3825 router is equipped with SFP ports (HWIC-1GE-SFP with GLC-LH-SM=) for fiber optic connectivity and also has a HWIC-1CE1T1-PRI installed The Cisco 2811 routers at the remote sites are each equipped with a WIC-1SHDSL-V3 module for SHDSL connectivity and with a WIC-1B-S/T-V3 for backup ISDN connectitivty.
In normal time the routers are using the SHDSL to Fiber optic connectitivty for communication. This has already been configured and is working. Now, there is a need to implement a backup connection between these sites such that in case the SHDSL or fiber optic connectivity fails, the routers should automatically dial up the backup ISDN connectivity so as to ensure business continuity.
ADSL line do not activate. Telco Confirmed Like is Okay . They have tested no issue observed. Router replaced but did not work. Supspecting Firmware not compatible with telco . Not sure how to confirm on this.

One of my branch offices is connected to an ADSL line as well as a VDSL line.Since I really don't need the ADSL line I came up with the idea to use it as a backup line.So I searched google and found this nice little article URL. I wonder if the router will switch back to the primary ISP if the primary line comes up again?
View 3 Replies View RelatedSite A, site B, site C, site D is connected using leased line each other. We are using Cisco 1800, 2800 and 2900. Each site also have Internet connection using ADSL connected to firewall, we are using pix 501 and ASA 5510.My question is, can i use the existing ADSL line to be use as a backup line if the leased line is down on any of the site??
And i want it to trigger itself, once the leased line is down, the firewall UP the backup line? something like that..

View 1 Replies View RelatedI'm about to install a new E1 onto my 3845 as backup line for my data network. We usually use VWIC2 cards since our infrastructure covers EU and US sites. But this time, I ran out of stock and so did my supplier. I have a VWIC-1MFT-G703 card here but not sure if it would work. What is the difference compared to the regular VWIC-1MFT-E1 ?
FYI, I run 12.4 T train release on my 3845s.
We are currently running Cisco prime 4.1 and want to make sure there is a backup of the configurations from our switches and routers. The VLANconfig is not collected according to the devicestatus dashboard. i am aware there were a known issue with LMS running on a virtual server and vlan not being able to be collected, is this issue resolved? i have tried the various workarounds with TAC support and it hasnt worked. We have the running and startup config collected for our devices when looking at the device status dashboard. does this mean if a switch crashes we can restore the config to a new switch immediately?
i saw there is a version 4.2. maybe this version resolves the issue with LMS on a virutal server? i cannot find the download to upgrade to 4.2 in the support section though.
Is it possible to create a job what automatically export the devices configs that are in the folder CSCOpxfiles medemushadow? It would be wonderdul if CW could export the .cfg files into a .rar and send in email or something like this.

View 5 Replies View RelatedHow to get this VC traffic through this network. I am quite new to ASAs, and I feel I am making a tonne of headway
The setup: The VCS Expressway is currently sitting within the DMZ (ip 172.16.10.10) which is NAT'd to 208.118.125.130. The internal VCS Control is pointed to the the VCS Expressway within the DMZ (as it is designed to do).
I have accessibility from the DMZ to the internal network. And from the DMZ to outside seems works partially (more on that below).
The problem:
Calls signalling is able to get through my network, but not media. IE, the call initiates, but media does not connect. Furthermore, I registered an internal endpoints (10.2.20.118) to the DMZ expressway (172.16.10.10). The registration works fine, but again, when I call to another endpoint (internal GK register endpoint to external GK registered endpoint) the call sets up, but media doesn't establish.
Here is the network topology, and below that is the run config.

Found you on Google and prays that the regulars here will take pity on a former Juniper admin. I've got a brand new shop to handle that is all Cisco including CUCM 8.x and I have zero Call Manager experience. How to enable international calling for a single user
[code]...
brief flow/steps for making sure a user can dial international? I figured it was as easy as making sure their DN CSS had the ability to do so, but apparently not.
In CUCME if you do not configure any translation rules and leave the system mainly at default, when a call is routed to the PSTN the CUCME system sends the true calling party ID which would be a users extension number. Is it correct to assume that a CUCM server based system, when too left at the majority of default (without translation rules or stripping etc) that it will send the true calling ID to the gateway?
View 1 Replies View RelatedJust recently bought a Linksys E4200 router and it's been rocking so far! I upgraded from a WRT320N. However it seems that calling with SIP (using my Voip Buster account) doesn't work anymore.I don't seem to be able to register with the Voip service. Port is the standard 5060 (if my memory serves me well, I'm not at home now) and I already activated on the router the special tick for Voip ALG calling. Router is upgraded to the latest firmware and it's the V1 router.With all of the above, I still can't connect using SIP to VoiceBuster. It worked like a charm with the WRT320N so it's something with the router?.

Every few minutes my WGR614v6 loses connection to the cable modem though the wireless in-house is strong. Cable modem being reset does not work. Resetting netgear router brings us back online but only for a few minutes. Have replaced power supply to router and it is still occurring.We have a desktop and 2 laptops online. Also, the notebooks always drop to 18mbps while the desktop stays at 54mbps.
View 2 Replies View RelatedMy computer has developed a habit of spontaneously having no internet connection even though it says the signal is as strong as it can be. When I began to investigate the issue I ran some diagnostics and the Internet IP ping test failed. I have no idea what that means or how to fix it. I did do a ipconfig/all on a c prompt and have the results I can post if anybody wants to see that. Beyond this I can't lend much more except to say that when it happens I can click on the troubleshooting and while it is trying to determine what the problem is (usually takes at most 30 seconds) the issue resolves itself and I can resume doing what I was doing. Last night was the worst it ever has been I had to restart my computer completely but once it had gone through the boot process and was in Windows again it was fine.

I have wireless router F5D9230-4. I use this every day to connect to my employer's corporate network from my home, using a VPN connection via Cisco AnyConnect Mobility Client.
Just about every day my VPN connection is interrupted and, although it "thinks" it is connected, it loses connectivity to my company's corporate resources. This occurs even though I'm connected to my router using a Cat5 cable. While this VPN connection is lost, my Internet connection keeps working.
When I use the same computer, even wireless, connected through other networks outside of my home, the VPN connection is never lost (or at least never that I remember).
When I wire my computer directly to my cable modem, this problem does not occur and my VPN connection stays connected throughout the day.
Note that I reset my wireless router to all default settings other than the password to access its management utility, to avoid any "weird settings" coming into play.
I wonder if this has to do with "VPN Passthrough" or the windows 7 firewall conflicting with my router's firewall?
I've been working with the IT department at my job for weeks on this and a resolution doesn't seem to be coming from that direction. I'm on calls every day that use this VPN connection and it's to the point where these VPN connection losses are embarrassing to me.
I have a Cisco 2800 series router with E1 PRI module at Head Office,and Cisco 786 with single ISDN BRI port,When I dial from either side only one B channel is up ,means 64 K only.
