Cisco WAN :: 3750G QoS And Voice Call Break Ups
Mar 6, 2011
We have installed a SRST in one of our remote offices. They have ISDN Primary, and we have a 6mb MPLS link to our main HQ with 400k of QoS on the line. During the day, both Internal calls over the MPLS and external calls over the ISDN break up, but it doesnt happen all the time, i.e in a day the morning will be ok, then the users experience the break ups in the afternoon, then its everything is ok again.
The only factor that the calls share is the Lan infrastructure i.e the 3750G switches (7) of them which are stacked.We did have MAC flapping errors, and our telecoms provider suggested that it maybe these causing the issues, however we have got rid of all MAC flap errors, and are still receiving voice break ups.
Because the Lan switches are the only "item" both calls share, I am wondering now if the setup of the switches is correct. [code]

Has any come across show ver memory details on 3750G-48PS as below, One of our Catalyst 3750G running software 12.2(44)SE2 shows unexpected DRAM as below:
cisco WS-C3750G-48PS (PowerPC405) processor (revision F0) with 0K/12280K bytes of memory. This would equate to around 11MB memory which does not seem right... Is it a known IOS bug?

I have a 3845-Mb that has a username and password already on it. This needs to be wiped as its a sold unit. However i cannot break into teh IOS in Hyperterminal using Ctrl-Break either as it boots or after teh IOS image has loaded (after it shows Decompressed image {ok} etc). I have tried several break key combinations such as ctrl+F6+break and they dont work either. On boot the unit does show Password recovery Functionality is disabled. IOS image is 12.4(13r)T.

I have over 20 units doing the same thing and it seems to be a software isssue but i dont see any bugs or posts on it. This is only on 2960S switches and not 2960 or 2960G units.
If i use the password reset feature to break the units into rom and then type "boot" instead of power cycling the unit, they will fail MBIST post tests. If the unit is power cycled or left to boot normally on its own, there is no issues and all post tests pass. I know MBIST is Memory Built In Self Test and was thinking maybe breaking the unit into rom disrupts those memory tests for some reason. I tried the following software and got the same results with all of the images:
122-55.SE2
122-55.SE
122-53.SE2
122-53.SE1
Logs attached are from the same switch, one with password reset procedure used and while left to boot on its own.

I am trying to come up with a standard way to configure controllers for my field guys. I'd like to just have them paste in a config that has all the settings, like we use to be able to do on aIOS. I am not seeing away to break out of the wizard so that they can just paste in a config. Do you have to go through the wizard in order to get to a CLI ?

I have a Dell Latitude E6410 laptop that does not have a Serial port or a Break key on the keyboard. I have a Prolific PL2303 USB-to-Serial adapter which is installed and I can access the CLI ok with this setup via HyperTerminal.
My problem is that I am unable to break into ROMMON using the break sequence Ctrl + Break (as there is no break key). I have also tried TeraTerm with the break sequence of Alt + B.
Additionally, I have tried setting the baud rate to 2600 and pressing the space bar for 10 seconds to no avail.
when I may need to break into ROMMON.

we have the following setup for our network :
UserNetwork - ASA5550 - WAN Router 2911 - ISP Netowrk - Branch Routers 877s / 1941s
Since last week we started noticing this problem that the branch users started to complain of slow application response.. After verifying it with the ISP and middle network we noticed that if i ping from my machine (ie usernetwork) to the WAN Router interface (facing the ASA) , i get time outs.. which is strange cause this is directly connected to it via ethernet cable.

I have a 887 setup as a EasyVPN server, and a 861 as an EasyVPN remote - network extension mode with split tunnelling.This works fine - I can ping and connect to machines across the tunnel.However if I setup a VOIP handset to connect across the tunnel it registers and calls work, but drop after 30secs....I know this is normally a firewall or nat problem, are easyvpns firewalled or natted?

I would like to use the Cisco ATA 186 as a SIP device with Cisco Call Manager 7. However, I have found that the SIP firmware for the Cisco ATA 186 is unsupported by Call Manager 7.Therefore, In order to use the ATA as a SIP device with the Call Manager, I believe I will need setup the ATA as a 3rd Party SIP device by doing the following:
1. Disable the TFTP option within the ATA, so that the SIP firmware is not overwritten by firmware from the TFTP server.
2. Install the 3.2.1 SIP firmware on the ATA, since the ATA is currently running the 3.2.4 SCCP firmware.
3. Register the ATA, as a third-party SIP device, with the Call Manager .Should I register the ATA as a 3rd party device?

I have a 2811 with CME 8.5; I recently added a SIP trunk and can make & receive calls just fine. I noticed today that when connecting to an external IVR system, I can't send additional tones (press 1 for Sales, for example). I have two DIDs, same provider, both doing the same thing. The config for one of my SIP trunk dial peer and translations are shown here - I think this is what's appropriate to review but can add anything else that's necessary. I've also omitted some dial peers for X11 and international dialing for brevity.

I have CUCM 8.5 in a lab environment that connects to a Cisco 2801 which has a VIC2 FXO card on board, I have believe that I have configured the MGCP correctly and also configured my CUCM correctly but I'm just getting a fast busy when I make a call through the PSTN, I have tried removing the Ethernet cable from the Router just to test what happens when I dial external and again I get fast bust.
Here is my configuration setting: -
From CUCM gateway details:
Gateway Name MGCP
Protocol MGCP
AALN/S0/SU1/0@MGCP
AALN/S0/SU1/1@MGCP
AALN/S0/SU1/2@MGCP
