similar to: Hardware phones supporting speex?

I'm not an expert either, but I see people choosing iLBC over speex all the time with asterisk; partly it's because they have more market share in hardphones, and partly it's because of marketing and such. (another reason is that iLBC source is included in asterisk, and speex is only compiled in if you have the speex development stuff on your machine when you compile

I've just gotten off a skype conference call and it pisses me off that the quality of skype is higher than my asterisk calls. Is there such a thing as a super high bandwidth codec? In a situation that you have the bandwidth to share is there something that I can use for important calls when the situation warrants it? TIA, Dean -------------- next part -------------- An

Compared to todays PDAs the GameBoy Advance (GBA) is low spec. it has a 16MHz ARM7tdmi RISC processor. 32-bit but it can handle 16-bit instructions in a mode that resembles "bytecode" (a 32-bit instruction is executed using a 16-bit instruction). I got a feeling that the GBA would need a FPU. For more information on the GBA visit this info page:

Good day, I have a puzzling issue that people in the IRC channel recommended I post to the list so here goes :) I am trying to call a SIP softphone from an H.323 hardphone. The hardphone is connected to a Definity Prologix R12 PBX with a MedPro card and a CLAN. The Avaya is setup to send any call to extension 1609 down an H.323 trunk group that is destined for the Asterisk server. When I call

I'm trying to understand why vendors keep making 100Mbps integrated 1-port switches in their hardware SIP phones. Even the recently-announced D40 and D50 Digium phones are limited to 100Mbps. Only the more expensive models (like the D70) can run at 1000Mbps. However, you can't expect a firm with hundreds of extensions to buy the most expensive model... And gigabit speed is important when

Also, you would be sattisfied with the narrowband decoding because the GBA sound quality isn't very good, however, that depends greatly on what you're going to do with speex on a GBA.... (an RPG with audio dialogs? ;-)) also, using a DSP in a GBA Cartridge sounds like overkill to me, however, that depends greatly on what are you developing and what's your target audience....

Hi, I have configured a certified asterisk 13 server with chan_mobile and res_pjsip. I have a Cisco 7940 hardphone and I use ekiga as softphone client. Now the problem is, using the hardphone I'm able to call the softphone and hear everything properly. But when I call from the hardphone to some number that has to be dialed via chan_mobile, I'm not able to hear what the other side says (I

Are you supporting wideband or just narrowband? Jean-Marc

Can anyone recommend a good cordless user-configurable SIP hardphone that is readily available in the states and doesn't cost $300? There seem to be a plethora of decent and affordable corded phones (like from Grandstream) but the search for a cordless unit seems elusive. I purchased a vtech 8100 online only to discover after receiving it that it is locked to vonage service. Thank you.

Hi all, I cover some VoIP issues. I was at VoIP developer conference and asked an embedded manufacturer (we're talking Wi-Fi phones) about supporting Speex in their embedded products. He said that Speex was good but it's too many things to too many people and that he couldn't supported it in his embedded products for the following reasons. * Code size must be extremely small * Data

I've got Asterisk up and running nicely using a couple of different softphones. Audio quality is suffering a bit due to the hardware that I am working with. So I tried to use a Polycom hardphone but the politics is enough to give you a headache. Polycom seems to support SIP only if you buy it thought their vendors. So I'm looking at a Cisco phone. Has anyone successfully implemented

FYI, the Asterisk software PBX <http://www.asterisk.org/> has now incorporated my recent patches to support dynamic RTP payload types. As a consequence, its SIP implementation now supports Speex, so if you have a Speex-compatible SIP client, you can use it to make calls using Asterisk. Some caveats: - Only narrowband (8 kHz) Speex is currently supported; not wideband. (Unfortunately,

Hi all, I am very new to this group. I have a voip application (softphone) which uses narrowband codecs (G.711 and G.729).Even it has explicit voice quality enhancement dsp modules (Baackground noise reduction , Automatic Gain Control and Acoustic Echo Cancellation) the quality of the speech is not yet satisfactory. After doing a long term research to get better speech quality on this I

Does anyone have any recent news on the Virbiage FT201 IAX Hardphone? I'd *really really* like to deploy these phones instead of SIP hardphones, and I can't help but wonder if I'm going to shoot myself in the foot (or another sensitive area) by deploying a ton of SIP phones just to find the IAX Hardphones were released a week later... Thanks, Brian D'Arcy

In a "normal" frame that doesn't have in-band signalling (which nobody seems to use anyway), the frame starts with the narrowband information. If the frame is in wideband, then this will be followed by a bit of wideband information that starts with a bit set to 1 (narrowband starts with a bit set to 0). Have a look at what the Speex decoder does. You may actually want to have similar

I would love to see podcasters adopt the Speex format to deliver clear speech audio at wideband or ultra-wideband formats. However, podcasters want something that can easily play on Windows, Macs, and even Linux web browsers. The Speex website has some nice audio demos, but it doesn't actually offer any HTML embedded samples using actual Speex format. Would there be a way to do this with

Hi, I've been asked sometimes to tailor call history features embeded in SIP hardphones. For example, a cutomer wanted internal call to be taken out. Another wanted calls to sorted according specific criteria. 1. Have you identified a phone offering the possibility to display as Call History, an XML list produced on a distant web server ? With this feature, you would simply have to tell the

Hi, I'm banging my head over this. Usually, I'm using a SIP hardphone feature called "Call Pickup Starcode" to enhance BLF with Directed Call Pickup : basically, SIP hardphone (here a Thomson ST2030S) is configured to send an INVITE message whenever a BLF is pressed while blinking. The INVITE is build with the extension number (attached to the BLF that was blinking and pressed)
