QOS configuration for Wireless voice over IP

HI, I've been asked to install approx 5 wireless phones on a network that consists of the following:-
1 x 4006 core switch
8 x 3550 Access switches
6 x 1100 AP's (that are connected to the Access switches.
My question is this - does anyone have a basic QoS configuration that I can place onto the LAN infrastructure (Core/Access switches).
Kind Regards
Steve

Should refer to http://www.cisco.com/en/US/products/hw/phones/ps379/products_implementation_design_guide_book09186a00802a029a.html. Also Cat 4K should have Sup2+ or higher to support voice.

Separate vlan for wireless voice

Hi all, I'm about to embark on reconfiguring my home lab, at present I have just 2 vlans which are for VoIP and data, I'm going to split my network so I have the following:
Data VLAN for our home PC's
Voice VLAN for phones
1 wireless VLAN for home laptops
1 wireless VLAN for games consoles
1 wireless guest access so I don't have to give out my own ssid credentials
1 Management VLAN
My question is do I have a separate VLAN for wireless VOIP or do I just use the same Voice VLAN?
Regards

Martyn:
Both solutions are valid. You can use the current voice VLAN or create a new VLAN.
If you create a new VLAN you need to apply needed QoS to wired side as well.
If your current Voice VLAN is already configured for QoS then using it for wirelss voice is easier.
So the preffered option is to use your current voice VLAN for wireless voice as well.

Recording your own commands for the Voice Over Utility

To Record your own commands for the Voice Over Utility?
Is this possible?
How?
thanks

If you simply want to change the command used, or add an extra command that does the same thing, you just need to know that the file names are used as the name of the commands for Speakable Items.
If you open system preferences, the speech pane, select "Speech Recognition" at the top and then "Commands" on the next line there's a button there - it's labeled "Open Speakable Items Folder". Click on that and it shows you a folder containing all the global commands. If you want to change one of these, you can edit the file name. It's probably safer if you duplicate the file ("duplicate" from the context menu) and then change the name of the copy, so the original is still there in case of mishaps! I'm not sure if a comma in the file name would work but I suspect it wouldn't - none of the commands there have commas in them.
If you want to change a command in a specific application then open the "Application Speakable Items" folder and explore from there.
Another thing which might help is to go back to System Preferences and click on the "Global Speakable Items" in the command set list and then click the "Configure" button. There's an option there which will make more variations on the commands work.
The most complicated way is to write your own new speakable items. This gives you the most flexibility but also you need to learn some AppleScript to enable you to do it. If you want to learn AppleScript, check out the AppleScript resources - it does lots more than just speakable commands and the general resources should help you most.
Best of luck!

Is there a fix for skipping or repeating songs, or for the voice over to come on without pushing any buttons?

Is there a fix for skipping or repeating songs, or for the voice over to come on without pushing any buttons?
I only use this 5th generation Shuffle when I run. I don't have headphone issues because I use running headphones meant to handle sweat. However, my Shuffle will, halfway through a song, go back to the beginning, play a few seconds and jump back to the beginning again. Also, when this starts happening, the Voice-over comes on again and again with no buttons being pushed. I keep the Shuffled clipped to the waistband of my running shorts, so it probably does get a little sweatty, but not like it would if it were clipped to the collar of my shirt!
Is this a problem I'm going to have to live with? I never had this issue with my old Shuffle, which was the first of the clip-on Sheffles.

Hi punisherbv,
Are you using the beta? it's not fully secure, so try using Firefox 3 instead. If you are already using Firefox 3, it seems like what Firefox is saying is correct- the site is not supplying identity information. So what you could do is go to that exact site, then click on the little golden lock at the very corner of the page. Then, enter the 'permissions' tab and allow everything. Exit, and then try bookmarking the page!

QoS Configuration for NME-AIR-WLC

Hello,
I have a question on the correct QoS configuration for a VoIP deployment. I have followed the steps referenced here but have two questions..
1) The last recommendation in the list is to set DCA channel sensitivity to High to avoid changes during business hours. I think this should be Low? The manual states "Low—The DCA algorithm is not particularly sensitive to environmental changes."
2) The recommendation is to trust dscp on AP uplinks and to trust cos on the WLC uplink. However I can't find any configuration guidelines for configuring QoS if the WLC in question is an NME hosted in a 2921.
2a) The link between the switch and the 2921 is an 802.1q trunk so should I trust cos on this link rather than dscp?
2b) What configuration should be on the 2921? Create a policy-map and apply it to the uplink port?
2c) Should there be a service policy assigned to the In1/0 interface for the WLC itself?
Any thoughts appreciated.
Thanks,
Dave

Well I appear to have answered question 2 after I stopped being lazy and did some packet captures.
No configuration required on 2921 as packets captured from In1/0 and Gi0/0 show correct DSCP markings on RTP and SCCP packets.
Would still be interested to know on question 1 though.

HT203077 Is there any way to get other voices for the voice over? Alex is dull.

Is there any way to get other American English voices for the voice over--besides Alex?

Switchport QoS configuration for WLC

Hi guys,
I am having a question about switchport QoS configuration for WLC. In the "enterprise mobility deployment guide 4.1", it says we can use both either "mls qos trust cos" or "mls qos trust dscp", depending on the mapping, however looking through Jerome's video tutorial on QoS in youtube, he actually mentioned that we need to keep this value as "mls qos trust cos", and I have also read from somewhere else that since controllers are layer 2 device, we do need to use "mls qos trust cos" on the switchport directly connected to the WLC.
however I did see some configurations using "mls qos trust dscp" on the switchport, which is for 5508 WLC due to some hardware design in the 5508 WLC. so I just want to ask what is the differnece between these two commands when we use them for switchports connected to WLC, and does this command really specific for what controller platform we use or it only depends on code version?
thank you very much for your time and help.

Hi George,
Thanks for your reply, however I am still a bit confused on the difference between the two commands...
so in the deployment guide it does say we can do either one on the switchports connected to the WLC, so when should we use trust dscp instead of cos?
it sort of make sense when we talk about WLC is a layer 2 device hence we should use cos, but we also have packets marked with dscp values and I think the controller will keep the value without any modification, then that means we can also use trust dscp in order for this mapping to be done correctly, is this correct?
I did see some other people saying that when using turst dscp and did a packet capture, the values cannot be mapped correctly, but there are also cases that this works. expecially with 5508 series controllers, does it really have some hardware features that doing different things than the 4404s and the 2100 series?
but still, in what situation should we trust dscp on switchports connecting to WLC and when should we use trust cos as a best practice? or we should just forget about trust dscp for switchport connecting to WLC?
Thanks.

How to setup a 1262 aironet for Wireless N over 54mb

I've been trying to figure this out as the documentation leads me to think this can only be set to 54mb on wireless N. How can I configure a "AIR-LAP1262N-A-K9" to have wireless speeds over 54mb?
The config guide only shows settings for up to 54, but the specifications indicate it could go up to 300.
Is there something simple that I am missing?

U can get N speeds only if u have plugged all the antennas and then if the AP is configured for either one of the below..
1>> Open Authentication with no encryption
OR
2>> WPA2 with AES as the encryption.
AND
WMM enabled and also with all MCS rates enabled..
Please do the same and this will help u in getting the N speeds..

What is the recommenden access port QoS configuration for 8900/9900 video enabled phones

Hi all,
we are currently starting to roll out some video enabled 9900 and 8900 phones in our network. In the past we did not use video and configured the access ports on our Catalyst 2960 switches with "auto qos voip ciscp-phone". This however creates a policy which does not include a class-map to correctly handle the AF41 video traffic coming from those phones. I have thougth about extending the autoqos policy with a AF41 class-map but am not sure if this is the right way to do it.
That's what I have in mind:
class-map match-all AUTOQOS_VIDEO_DATA_CLASS
match ip dscp af41
class-map match-all AUTOQOS_VOIP_DATA_CLASS
match ip dscp ef
class-map match-all AUTOQOS_DEFAULT_CLASS
match access-group name AUTOQOS-ACL-DEFAULT
class-map match-all AUTOQOS_VOIP_SIGNAL_CLASS
match ip dscp cs3
policy-map AUTOQOS-SRND4-CISCOPHONE-POLICY
class AUTOQOS_VOIP_DATA_CLASS
   set dscp ef
police 128000 8000 exceed-action policed-dscp-transmit
class AUTOQOS_VIDEO_DATA_CLASS
   set dscp af41
police 1500000 8000 exceed-action policed-dscp-transmit
class AUTOQOS_VOIP_SIGNAL_CLASS
   set dscp cs3
police 32000 8000 exceed-action policed-dscp-transmit
class AUTOQOS_DEFAULT_CLASS
   set dscp default
police 10000000 8000 exceed-action policed-dscp-transmit
How do you guys do it ? Is there some documentation for this ?
Thank you for your kind help
best regards

Hi
You have to keep this table on your mind. Your configuration is fine if your configuration for SD video , but if for HD video , it is not ok you have to change video bandwidth at least 5M.
Traffic Type
Layer 2 CoS
Layer 3 IP Precedence
Layer 3 DSCP
Voice RTP1
5

EF
Voice control

AF13
Data
0-2
0-2
0-AF23
*Interactive Video "AF41"- Sensitive but can tolerate packet loss of about 1% and latency almost same as voice.
*Streaming Video "AF13" - Less sensitive - can tolerate about 4-5% packet loss and latency of about 4-5 seconds.
*HD video conference will require between 5M to 16M , but SD video conference will use 384K to 1 M
Note:-Video QOS , if you will assume that your video conference will use around 384K , you have to add 20% because video conference include voice so the total bandwidth 460K.

SRW Series QoS configuration for VoIP

Hello Cisco experts,
I have SRW224G4 switch in an office connected to the internet through port1, Asterisk server through port 9, Internal computers through ports 16-24.
Currently, voice is cutting in the inbound direction when computer users are using Internet. I am trying to make some QoS configuration in which remote IAX2 phone, which uses UDP port 4569, will not be affected by Internet usage made by internal computers.
I have logged in to the switch management webpage, I found a section for (QoS), but I need some help in specifying which parameter should I configure.
Internet connection speed is 1mbps DL / 512kbps UL. I can configure Asterisk to mark packest with some TOS if required.

One way to do it would be to configure Asterisk to assign a DSCP value of 46 to voice packets.
Then on the SRW224G4, use:
CoS Settings tab / QoS mode: Basic
Basic tab / Trust mode: DSCP
That would give priority to voice packets inside your network.
Possible problems:
your ISP will most likely clear DSCP markings on packets going out of the network
rare case: your ISP might charge you more for packets marked with DSCP 46 (not likely on an ADSL connection)
bottleneck will be the ADSL router, so if possible, you should implement QoS based on DSCP on that device
if some PC based software uses DSCP markings, it'll get priority also
Hope this helps!
Cheers,
Tamas

Audio input is gone. What plug/adapter do I need to plug in a rode mic for fcpx voice overs? Any help will be much appreciated.

Hi,
First time user.... Bare with me.
My old imac had an audio input and I could simply plug in my rode mic and perform voice overs etc.... Now the new imac has no audio input.
I gather I need an adapter, but am I really stuck buying the iRig Pro at $219? Will this even work for voice overs in FCPX or is there a much cheaper and cheerful option for this problem that apple could have avoided in the first place...
Any advice will be welcomed and appreciated.

Thanks Very much A Brody!
None of the research I did came up with this option. Really appreciate it.

IMac-Questions for professional voice over recording

I'm about to purchase an iMac.Hi-I've used a PC for years recording VOs.Now I'm considering an iMac (3.20GHz Intel Core i3,4GB 1333MHz DDR3 SDRAM - 2x2GB,1TB or 2TB Serial ATA Drive,ATI Radeon HD 5670 512MB GDDR3 SDRAM) Anyone willing to share some ideas and answer some questions I have about the eventual switch? Since I enjoy things very simple,until now I've achieved great results with a Sennheiser MD421-II mic,DBX 286A preamp/processor and Audacity on my PC. I'm a bit technically challenged when it comes down to knowing the inner workings of computers and Macs but I was told that I might need to look at the sound card that comes with the above iMac and consider upgrading it? Is this true? Is the graphics card adequate? Are the processor,Ram,hard drive adequately sized for VOs? Also...with the PC,my signal chain (if you want to even call it that: ) is mic,preamp,processor to computer via miniplug. Can I use the same with the iMac or do I need extra equipment? Thanks! So many questions....Thanks for any help or suggestions.

That computer will do everything you want and more. I have the same thing.
I haven't used the input on it yet, but the output is great minus 1 fault and that is the ground seems weak. I have two rokit8 monitors hooked up and was getting horrible ground loop noise, didn't happen in my old imac, just the new one.
Now in terms of software you are gonna be in recorders heaven. I have both garageband and logic pro 9 on mine. Garageband can be used for simple recordings, or fairly in depth recordings depending on the project and how good you become with GB. Logic pro is about as professional as you can get, a lot of the songs you hear on the radio are recorded using logic.
Now with the hardware it depends on your taste, I personally have never heard better sound from a computer then the setup I have now. And I am pretty sure I could make professional voice overs using the built in mic . But the quality of the sound card in question depends on you.
I would bet you would be content with the sound card they come with.

Wireless Voice over IP

Dear forum members, I have deployed quite a few WLAN environmnets but none so far for
Wireless VoIP.
If I have to design a system for both data and Voice isnt reccomended to create 2 VLANs/ 2 SSIDs, one for voice and one for Data?
Also what needs to be done on the Controller to accomodate the Voice? what are the authentication mechanisms?
Anyone has any great document to share?
i would appreciate your help on the matter.

Best mic setup for FCE voice overs?

Hi - I need to add a voice over to some footage. Any recommendations on microphones... Would the standard audio in jack be good enough, or would a Griffin iMic be the best option?
Cheers for the advice.
15" MBP 2.0GHz 2g RAM Mac OS X (10.4.7)

I use the M-Audio Fast Track guitar/mic recording interface. You can hook-up your XLR mic or use it to play your guitar in Garageband.
