VOIP Card on Cisco 2821

Hi,
I want to set up a VOIP environment in my company. The topology is like this:
PBX1-75xx-WAN-2821-PBX2-phone
PBX2 is a panasonic TD88 Model.
The dial plan will be (from phone-set):
1.dial 8 for PSTN access direct to PBX2
2.dial 9 for accessing branch office under PBX1.
I want to know which module/card shall I choose on cisco 2821 router?
Thanks
Joey

Hi Ivan,
I know little about telephony. But I think the interface is analog. Because it seems using RJ-11 interface on PBX.
Actually,TD 88 get 8-port for connectiing to telecom company. Now we just used 4 of them. I want to use the other 4 interface for voip that may be connected the Cisco 2821.
Do you have any recommendation?
Thanks
Joey

Changing the Compact Flash on Cisco 2821 Call Manager Express

Hello All,
I'm gonna have to swap the compact flash on a Cisco 2821 who is serving as the Call Manager express and the Dialling Router.
What's the best way of approaching this? As far as i know it doesn't have a second slot? And i just can't plug it in and copy everything from 1 flash to another.
Must i copy all of the files on the flash to my tftp or? How can i be sure that everything will be copied to the new flash? I will be creating downtime i suppose? since when i'm copying towards the new flash the router will not properly work with the previous configuration

So i figured out that i can use the archive tar /create command:
To copy the entire flash towards TFTP:
archive tar /create tftp://X.X.X.X/flash.tar flash:
Now i will have to insert the new flash and probably format it first towards the correct file systems. Then i will have to use the next archive command:
archive tar /xtract "Here i am unsure of the syntax, i want to be copying and extracting the tar I backed up from the old flash"
After these steps are complete can i just reboot the router with the new flash card, won't there be any issues, since the startup config is on the NVRAM it will load the config properly, and i haven't seen any boot parameters but they shouldn't pose any issues since i'm not changing the flash slot.
Thanks for your assistance

I want to upgrade the IOS of my Cisco 2821 from Version 12.4(11) to v 15.1 (XB), but I have CCME v 4.2 (0), is there any problem if I only upgrade the IOS and leave the CCME as it ?

Thanks

CME is part of the IOS, so you can't upgrade the IOS seperately from CME.
That said, if this is a production environment you should proceed with caution and be prepared to roll back as you may find bugs, etc.
You should also look at release notes and make sure your phone firmware will still work or needs to be upgraded too.

Need a tool for flash backup on Cisco 2821 series routers

Hello Folks,
We have around 1200-1500 cisco 2821 series routers on those we are performing the hardware upgrade so we are taking the backup of all the files available in the flash of all the routers, we just want to know is there any trusted tool available to make this task easy to schedule and take the backups.
Please let me know if you know any tool name.
Thanks,
Raja.

Sorry, I don't know any tool that makes a backup of the whole flash...
You could fo it with from ios cli maybe execute it automatically...
To flash:
archive tar /create flash:/backup.tar flash:/
copying directly to ftp should also work:
archive tar /create ftp://test:[email protected]/backup.tar flash:/

P35 Neo2-FR and VOIP card questions

Hi,
I'm evaluating buying this motherboard and would like to know a couple of things:
- Do all P35 Neo2-FR include ALC-888T codec instead of ALC-888? If not, how do I find out which ones do and which ones don't? I'm asking this because it clearly says "Optional" in the product web page, but it doesn't specify which ones have the ALC-888T codec
- If I understand correctly the only difference between ALC-888 and ALC-888T is VOIP card support, is this so?
- Has anyone tried using this MB with a VOIP card? How did it go? (Ease of installation, ease of use, sound quality, etc.)
- Are VOIP cards common? I just did a quick search at Newegg and I couldn't find any. Not a single one ???
- I think the P35 Diamond MB comes bundled with a VOIP card. I guess the P 35 Neo2-FR DOESN'T come bundled with one, am I correct?
- If anyone has bought a VOIP card to use with this board, where did you buy it and approximately how much did you pay for it?
Any help GREATLY appreciated

Thanks everyone for your replies.

that's only P35 Platinum, not P35 Neo2-FR :(
city_zen, is VOIP a must-have feature for you?
No, not really a must-have feature, but it would be a very nice thing to have on my board. I'd definitely use it if it was in fact available (i.e. ALC-888T) and I can get a hold of a VOIP card. However, it's looking like that's not very likely to happen ... Oh, well ...
Anyway, this is a very good board even w/o the VOIP feature, so I'm still considering buying it.

How many Voice connections can cisco 2821 support?

Good day.
I have a cisco 2821 with EVM slot, NME-X slot and two HWIC slots. I have 4 port FXOs on the two HWIC slots. The EM-HDA-8FXS module on the EVM slot can handle 8 FXS connections. Please i would like to know if there is an EVM module that can do FXO connections and also how many voice connections can this router handle in total. Can the EM-HDA-8FXS module handle both FXS and FXO connections?
Hope someone can help me out. My deadline has already passed.
Regards,
Obinna.

Hi, already replied to this in the appropriate forum.

Upgrade Cisco 2821 to IOS 15

Hi everyone,
I am currently going to upgrade the Cisco 2821 IOS to version 15. Do I need to apply any licences for advice ip service after the upgrade. thanks for the help in advance.
Kind Regards,
Lei

ISR G1 doesn't have any "licenses". Just make sure you are upgrading to the same Feature Set as your old IOS.
Read the Release Notes carefully. Make sure you have adequate DRAM and Flash.

Netflow export on Cisco 2821

Hello,
a question or more a problem with netflow exports on Cisco 2821's.
I configured netflow export on a Cisco 2821 with IOS Version 12.4(24)T
ip cef
interface FastEthernet0/0/0
description to XXX
ip address XXX
ip flow ingress
ip flow egress
duplex full
speed 10
ip flow-cache timeout active 1
ip flow-export source GigabitEthernet0/0
ip flow-export version 5
ip flow-export destination XXX XXX
The netflow collector shows "only ingoing traffic" on interface FastEthernet0/0/0 and
"only outgoing traffic" on interface GigabitEthernet0/0.
Same problem with an IOS Version 12.4(20)T1 on other Cisco 2821's.
But same configuration on other Cisco 2821's with IOS Version 12.4(11)XJ4 work well.
Any references/suggestions or explanations?

#It's surprising to me that it's even possible to configure both directions on a single interface.
#It's generally not a good idea to configure both directions among interfaces on a single router.
--> It is possible. ;-) I need QoS (DSCP information) for ingoing traffic and
--> and for outgoing traffic of this interface FastEthernet0/0/0.
#How's g0/0 configured "ip flow" wise?
--> There's no netfow configuration on this interface, only on Fa0/0/0.
-->#sh ip flow interface
--> FastEthernet0/0/0
--> ip flow ingress
--> ip flow egress
#Maybe you're seeing "only outgoing traffic" on
#interface GigabitEthernet0/0, because those are incoming traffic through fa0/0/0
#(where IOS ignores the "ip flow egress" part) and flowing out through g0/0?
--> You're right. The outgoing traffic at Gi0/0 is the ingoing traffic at Fa0/0/0.

Can I use Sandisk Compact 4GB Flash card on Cisco 2800 series Routers

Can I use Sandisk Compact 4GB Flash card on Cisco 2800 series Routers

Yes can confirm the Sandisk Compact 4GB Flash Card works in 2800 series, the exact card above...
Initially I attempted to shrink the partition on the card to a 2GB FAT partition using the steps here http://timescience.wordpress.com/2010/08/09/how-to-downsize-a-4gb-compact-flash-card-to-2gb/
However when I inserted it into the router and tried a directory list it wouldn't have a bar of it...
*Jun 23 14:11:01.391: %FILESYS-5-CF: CompactFlash insertedrtrvoip#dir flash:%Error opening flash:/ (Invalid DOS media or no media in slot)rtrvoip#format flash:
So I ended up running a format flash and voila, 4GB of flash memory no problems...

Cisco 2821, add 8 FXO

Hi,
I have Cisco 2821, currently we have pRI circuit terminated on it.

It is possible if you have enough dsp resources. You can calculate hardware need with Cisco DSP calculator - http://www.cisco.com/web/applicat/dsprecal/dsp_calc.html

RPS 2300 together with 3750 - 48 PoE and Cisco 2821

Hi,
I'm wondering what kind of power modules to include in RPS 2300 (750 or 1150 Watt) to provide redundant power supply for 1 x Cisco 2821 router (standart power supply) and Catalyst 3750 with PoE 48 ports.
Thanks

I am not qualified to answer your question... I would like to mention to be careful when calculating power for phones, because some of the phones (especially color) will take more power than others. We ended up only being able to support 24-ish phones on a 3750 due to power limitations.

Valcom 2001A single zone paging system with a Cisco 2821 FXS port

I am new at troubleshooting the Valcom paging system with Cisco 2821 router. I recently installed a Valcom 2001A that is connecting to FXS port on the Cisco router. The paging works but the ringing does not stop when the page extension is dialed (you can talk over the ringing). I was told to use the Valcom 9970 to work with the FXS port on my router. Will the V9970 worth with the 2001A or in place of it? Is there anything else I need to know to perfect this install? Thank you!

Put the command 'forward-digits extra ,,,,01' on the outgoing POTS dial-peer. Each comma is one second of delay.

Traffic Shaping on Cisco 2821 router

I have two sites and connected with MPLS links of 2MB with Cisco 2821 routers. Now a requirement came that two sites will have additional server ( one each location - for data replication purpose) and 75% of the bandwidth needs to be allocated to data replication servers on each site and rest of 25% bandwidth will be utilize for both sides normal traffic.
Is there any additional modules to be added on each router to isolate the traffic. Please let me know.
Thanks,

To expand on the information that Collin provided . . .
If you really want to cap the bandwidth to a class of traffic, i.e. truly limit replication to 75%, you can add a policer or shaper to a class, similar to what Collin shows.
e.g.
policy-map RestrictAltiris
class Altiris
bandwidth percent 20
shape average 1500000
However, like Collin, since CBWFQ guarantees bandwidth allocations, you rarely need to cap bandwidth if you, for instance, insure your other traffic gets the other 25% (i.e. 100% less 75% for replication).
e.g.
policy-map RestrictAltiris
class Altiris
bandwidth percent 75
(NB: BTW, there are other rules pertaining to bandwidth reservations, but prior examples, both Collin's and mine, should suffice.)
Also BTW, since you mention MPLS, and since MPLS often allows multisite communication, if there are more than just these two sites that can communicate with these two sites across their 2 Mbps links, other considerations apply for dealing with such a situation.
PS:
Although software based QoS should meet your stated requirements, there are optional modules to provide "WAN optimization", see http://www.cisco.com/en/US/prod/collateral/contnetw/ps5680/ps6870/product_data_sheet0900aecd8058218c.html.
PPS:
BTW, when Collin describes:
". . . but when the link gets congested the router will limit the traffic for this host to 20% of the total interface bandwidth, and all the remaining traffic to 80%.", this might be just a bit misleading since when the link is congested individual classes aren't really limited they are instead guaranteed their bandwidths as a minimum, not precisely the same thing. For example with 20% and 80% guarantees, either class could still obtain unused bandwidth from the other class while the link is congested.
[edit]
This being true, for something like what you describe, I would recommend using the least amount of bandwidth guarantee that data replication needs. Assuming your other traffic, on average, doesn't consume more than 25% of the bandwidth, you might find even providing replication only 1% for a bandwidth guarantee works fine. Why you would want to do this, by lowering the bandwidth guarantee for replication, you allow other traffic to burst. Such bursting capability normally improves any kind of transactional or conversational applications and doesn't (usually) unduly delay replication.

Configuring lines 1 60 on Cisco 2821

Hi all,
I'd like to know what is necessary to configure the parameter line 1 60 in a Cisco 2821 router with a two E1's direct connected in a interfaca VWIC2-MFT-E1 and two PVDM's modules installed.
When I try to enter the line "router(config)#line 1 60" the ios returns an error message that there are no physical hardware to support "line 2". I just can enter line 1.
Which is necessary to do this?
My best Regards,
Adriano

try to do a show of the interface using the following example and see the output.
#sh voice po 1/1
