Cisco WAN :: 4500 - PDLM RTP Audio
Dec 12, 2011
Im trying to locate the PDLM for the RTP audio for the 4500 series switch,
System image file is "boot flash:cat4500-entservices-mz.150-2.SG.bin"
Cisco WS-C4507R+E (MPC8245) processor (revision 7) with 524288K bytes of memory.
MPC8245 CPU at 333Mhz, Supervisor IV
Last reset from Power Up
8 Virtual Ethernet interfaces
48 Fast Ethernet interfaces
100 Gigabit Ethernet interfaces
403K bytes of non-volatile configuration memory.
It seems to be an easy task for routers:

But not for these 4500's

I have a user that uses an ASA 5505 in NEM to have his/her laptop and Cisco IP Phone at home. The ASA 5505 establishes a tunnel to an ASA 5510, which is connected and speaking EIGRP to our core switch. Off of the core switch we have our CCM cluster.
The issue happens on the first call after a long period of no calls. After if happens on the first call, he/she can continue to make calls without the issue. I though it was a timeout issue, but his/her ASA configuration is the exact same. Also, he/she is using the same group policy, tunnel-group etc. as everyone else with the same setup.
This issue happens regardless if she has a PC behind the phone or not.Internal calls and external are both affected.
I am aware that most one-audio issues are RTP connectivity issues between the two endpoints. I can clearly see in the routing table of all of our routers, that the route to the subnet her phone is on has not changed for days, and she has had the issue within that amount of time.
I'm looking for a good place to start troubleshooting that doesn't require me to to a pcap. If all else fails, I will do a pcap.

Im curious to know if there is a way, to stream music to my iPad from a drive connected on my network? Either by USB to the router or a hard wired NAS. Im aware of programs like Streamtome but this requires a mini server running on a PC which is want i want to avoid!
I know there are things like the slingbox etc but i cant believe its needed! If you can access the files on a MacBook on the wireless why not an iPad?

I would like to make my audio MP3 stories and audio books available to the visually impaired and others who can no read for any number of reasons. I have already written and recorded the material in MP3 format.I find that virtually everywhere I look I must pay, or the upload limit is so small that a story of any size can not be uploaded. I have an Ipage web site and two blogger blogs where I could post the link for listeners to download the text. I do need to do it all for free, since I am on S.Security.
Stated differently; I want to offer my audio books and audio essays for free from my blogs or website. I can not seem to find who will store my recordings (large enough to actually be a book) for free. The site should be easy to navigate so impaired patrons can use it easily. I did find one, yourlisten.com, but the user has to agree to buy something from their advertisers before they can download my audio text. For the user, then, the service is not free.Does any one know who will store and share my audio text for free?

I work from a computer that can not install any software(locked out), but I want to record good quality audio (at least 192kps) from websites, I've spent along time googling for a website that would record the audio (audio from a different website, i.e. streaming radio, etc.) which I could then download to my USB stick. I just can't find a website that does this, but I think I'm just not using the right search words

I am able to stream audio from a website when i connect directly to my cable modem but when the router is connected it doesnt work. I have tried resetting the router, ping the website and get "request timed out"The firmware is up to date version 2.25 I have tried other computers that access the same network and they also cant stream the audio.I have also turned off my windows 7 firewall with no luck I can access other sites I visit and stream audio just fine so I wonder if the router may be blocking something on this website?Is there a way to allow an audio stream to come through that may be blocked by the router?

I've got an ASA 5505 running 8.2 configured for solely as an IP phone proxy, it is the default gateway for the cucm box and PRI router, its inside interface is directly attached to the same subnet as all internal phones as well. Calls can be placed from either end, but after call is established, proxy phones does not hear audio from internal or pstn phones. The proxy phone registers with cucm with the remote internal IP of the phone that obviously cannot be reached by corp network.
Debugging from pri router shows the rtp traffic destination is the internal ip address of the proxy phone 192.168.0.50, why is the phone registering with its internal IP 192.168.0.50 rather than its Natted external IP 50.50.50.50 that can be reachable by cucm and other phones?Proxy phone is a 7945, after it registers, I do not see it under sh phone-proxy secure-phones, or sh phone-proxy signaling-sessions while on a call.

I have the WAP4410n connected to a SLM2008. I tried to change to 100Mb the port in the switch but then I lost the connectivity.
But it's a giga port and it must work as a giga port. The new firmware must resolve the problem, and not to be a work around. Or what will be the next, not to use N, only G, or only 20MHz or...
I need the WAP4410n for streaming audio and video?

I am trying to hook up a wireless projector and connect an old audio mixer to my Laptop wireless and in sync so that I can operate the projector video and audio from my laptop anywhere in the room. I have a 30' by 60' sanctuary in my church an old audio mixer hooked up to key board, mics and speakers and one cordless mic. I am considering purchasing a Epson Powerlite 96W Projector and the optional wireless LAN module but wondered if there was a way to hook up a Epson EX7210 projector wireless as it does not accept the optional wireless LAN module. Also we currently have a great singer and no musicians so I am trying to find church presentation software that would include lyrics, background effects and music to accompany our singer.

Advanced networking but have managed to get our small office IP PBX running over a SIP Trunk. The only real problem we are having is choppy outgoing audio when there is other heavy outgoing traffic on the network.
My understanding is that I need to set some QoS parameters, which I have played with but it didn't seem to be useful. I mostly dealt with allocating bandwidth. I now think I need to somehow prioritize the outgoing RTP packets from our PBX (which runs on a PC on our LAN) to avoid the choppy audio. My research shows this can maybe be done with something called DSCP 46 and my router does support that -- how to exactly set the configuration.
Our router is a Cisco rv180w.

I bought my first Dell laptop (Inspiron 7720) and I can't make my bluetooth audiosystem (Logitech Mini Boombox) to work. I've got positive experience on Fujitsu-Siemens Amilo Xi2550 and on HP Compaq 6530b, where I had to just download another drivers for widdcomm bt adapter. I tried to do this trick o this computer, but I get only three bluetooth peripheral devices, which I can't install, because there is no driver for them. What shoud I do to make audio transfer through A2DP to work?Bluetooth drivers are working, I am able to pair the device. Problem is in instalation of all services.

On several calls i noticed that the outgoing audio stops for 5..15 seconds randomly. I'd say it happens on an average of every 5 minutes.
When this happens, i can see that the value after "Call1 Packet error:" increases by one. Why just a wrong packet may stop the outgoing audio for so long? i've much more packet losts (about 3%) but they give me no problem at all.
Since a little and cheaper Handytone HT502 gave me intermittent audio too, but the effect was much better (audio still stops, but in a second it comes back), i wonder if is there something i can do by tweaking the WRP400 settings, I'm still using firmware 1.01.00.

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.

When I view my DCS-932L camera in the Main Console of DViewCam, I can here the sounds in the room being viewed. But if I record the video and play it back, there is no audio on the playback. I have the microphone on the camera enableI now have sound recording, however, the audio is about 3 seconds behind the video. Is there a setting somewhere to keep them synchronized? I have checked all the video sync checkboxes I can find.

I recently bought a Bose Soundlink bluetooth speaker and have paired it with both my ipod touch and ThinkPad w500. The iPod Touch sounds great, but the audio coming through the speaker via the w500 sounds like it is clipping, especially at normal-loud listening levels. Both the soundlink and the w500 have the latest bluetooth driver updates installed. The clipping occurs even when the main volume (and iTunes/Spotify) is turned down to 50% power.whether there is a way to reduce the "power" of the bluetooth signal so it does not cause the speaker to distort. Audio played through the speaker via 3.5mm from the w500 sounds great even at high volume.
Currently installed bluetooth drivers:
Bluetooth Enumerator (Microsoft)
ThinkPad Bluetooth 2.1 with Enhanced Data Rate (Broadcom)
Bluetooth Hands-free Audio (Broadcom)
Bluetooth Remote Control (Broadcom)

Have a new 4500-x (Comes with IPBase enabled), but I see only universal image is available for download (Which I understand has "all" features)...assume it is safe to use the latest universal image on 4500-x and the IPBase license will be automatically applied?
I also see there is a new rom upgrade available - Is this the correct procedure to follow: [URL]
Should I be doing the rom upgrade first?

I have a 4510R+E switch that won't change to the SSO redundancy mode. After entering the 'mode SSO' command, the switch reboots the peer supervisor (as it says it will), but after it comes back up it remains in RPR mode. I've tried rebooting the peer supervisor manually, rebooting the entire chassis, manually power cycling the entire chassis, and reseating the sups, but the switch remains in RPR mode. The issue started when I swapped the switch's supervisor with the supervisor of another 4500. The same issue was observed on the other 4500 as well, but after several reboots, I got it to change to SSO mode. Prior to the swap, both switches were running in SSO mode just fine.Since we're running IOS version 15.0 with the 'spare sup' license, I suspect the issue arose because of licensing complications (with relation to the chassis serial number and the like) when I swapped the sups....although this doesn't explain why the other switch changed to SSO after some troubleshooting.

how to setup this old switch 4500. It is running CATOS and I want to make sure that when I connect it to the network it doesn't create a loop since it has to be compatible with other vendors, not just Cisco.I don't have anything connected but these are my concerns: It doesn't show my lacp-channel (i believe this is what is used to for Teaming network cards), it doesn't show my trunk ports.
TestSwitch> (enable) show lacp-channel
No ports channelling

We inherited a lot of the equipment from another team of network administrators and every now and then, we run into a switch with some old code or configuration that was left behind and missed by us. Today, I discovered that CPP was enabled on 3 of our access-layer switches in one of the buildings we support.

We have a Cisco 4500 core switch and 2 Motorola AP 6532 access points. From the Motorola side the goal is to allow my corporate users access to network resources meanwhile offering my guest users only internet connectivity. My thought is to create two separate VLAN’s on my Cisco switch ex: vlan 10 (Business) 192.168.50.x and create another vlan 20 (guest) 192.168.2.x, also I made the proper configuration changes inside my Motorola AP device as well. From the Motorola I can ping myself but not my switch?
