similar to: Echo Problems with IAXy

Ok, I searched the lists and found no definitive answer. I'm assuming the IAXy has some primitive form of echo cancel, is there anyway to adjust this? Or any ideas on what to do instead. Here's the setup, this will not be a typical setup for our company however, well whatever. Anyway it looks like this: IAXy --> Netgear router --> Charter --> Level3 --> Asterisk --> VOIP or

I'm using iaxagent on a Droid X to connect by IAX to 1.8.3 at the office. 1.8.3 has sip phones. The audio is fine on the Droid X side. On the office side, they hear an echo of _their_ speech, not mine. The office uses sip-providers generally without any echo problem. Where do I start to figure this out? How do I narrow it down? Can I figure out if it is an iaxagent problem? Could using

I have been searching for a while and can't find anything specific like this. Here's is my setup: IAXy -- broadband network -- Asterisk -- TE110P -- Channel Bank -- POTS lines (FXO) Everything works fine except for the echo at the IAXy. There is no echo on the POTS end, so Asterisk is doing a good job of echo canceling. Is there any provisioning in the IAXy to do echo

Simply to say, in a quiet room, you can play a impulse signal and then find it's impulse response signal from the microphone. For example, if the delay between the impulse signal and its response signal range from 500 to 3000 cycles, you can buffer the far-end signal to 0-300 cycles and set the filter length to 4000. It is also called to align far-end signal and near-end signal. BTW: Speex

Hi Jean Marc, We are running the speex echo canceller code on a Windows Mobile smartphone using a TI OMAP 201MHz 850. We are making voip calls and audio is working without echo canceller code. Simply adding the following 2 functions whether the echo cancellation is wired in (ie we use the output frame ) or not performance becomes terrible. Note 2 separate threads are used to handle audio.

A Polycom 550 and a IAX client (Mozphone and ZoIPer were used) are having a conversation. Call quality is reported as good except for an echo with a 3 second delay. Most of my searches are saying echo happens only on the PSTN piece, but there isn't one here. Can someone point me in the right direction?

Hi Bradley, Yes, I experienced quite a lot of echo with my IAXy, until I switched analog handsets - in my case, it was severe acoustic coupling in a cheap handset.

Hi, I have three Iaxy devices (s101i) parts. Two of them seem to work fine. The third plays a loud repeating click sound when an analog phone is plugged in. I can provision all of them, and make calls to all of them. The clicking one will blink when a call is incoming, but no audio from the call can be heard on the handset, and the caller only hears silence. The same handset works on the

Thank you, Andreas Engel.

Hi.. I have to setup an extension in a remote location that will use a cordless analog telephone.. I am looking at the IAXY to do this for me..Basically the data path will be as follows... [Asterisk] == (NAT) == {Internet} == (NAT) == ATA -- Handset Since there are two NAT boxes in the path I know SIP won't work.. I also don't want to move the Asterisk box to the internet side of the

Hi, I'd like to try using a good quality microphone and a set of PC speakers (in the first instance) to create a powerful speakerphone; if I get that working, I'll probably try more elaborate audio equipment. For this to work, I'll need software acoustic echo cancellation, or the caller at the other end will constantly hear his/her voice echoing back. I gather Asterisk can do

I have a brand new IAXy I'm playing with. I do not get a dialtone on the phone, or any response at ll on the phone. No sound, no dialing, no ringing. The phone and wire are tested and known to be good. I think I have it setup correctly. When I give the iaxprov command I get this: #iaxyprov 192.168.1.90 iaxy.conf 02: c0 a8 01 5a 05: 11 d9 03: ff ff ff 00 04:

Hi, I've got an IAXy, and provided it with connection data - unfortunately didn't provide a fixed ip address, but left with dhcp. Everthing went fine, and I could work a while with it. After a restart of IAXy, it didn't negotiate a new IP address, nor used the old one. I even restarted the DHCP server and cleared its cache. No success. I went to another office with a different

For anyone playing around with IAXy(S100i) devices, I am making the following available: Windows IAXy Provision v1.00 This is a from-the-ground-up development of a means of provisioning IAXy devices using a Windows environment. For some users, being bound to Linux for IAXy provisioning is not viable or convenient in some cases. This application provides a GUI data entry for the various IAXy

I need a cheap simple adaptor for analog phones to use with Asterisk. It should be some kind of "configure and forget" type of device, to use at the office, or just throw it in a road warrior's bag and use it while travelling, to call back to the "mothership". I can't decide between iaxy and sipura. Can you guys help? Which one would you use? (and why?) I feel that iaxy

I'm having a problem with my IAXy not always connecting to my Asterisk box. When I pick-up the phone plugged in to the IAXy I get a busy signal. I have to hang-up the phone and wait a few seconds after the orange LED goes out and then try again. When this happens I don't see any connection attempts in the Asterisk -r output. When I do get the IAXy to connect to Asterisk I get a

Hi all, I have a Soekris net4801-50 board with OpenBSD 3.9 where I've configured a dhcp server and tested it with a regular PC connected directly via a crossover cable with success. The problem comes when I try to connect my IAXy device instead of the PC. I can see with 'tcpdump -nettti sis1' that the IAXy isn't sending any packets to the dhcp server. I thought my IAXy was bad

Hey Everyone, I recently purchased a few IAXy units for some testing, and have come across a some problems. One of them can be provisioned but will not ring the connected telephone. It also does not provide a dial tone when you pick up the phone. When a call is made to the IAXy one of the green lights on the board goes from a solid on state, to a flashing state that coincides with the

Yesterday I was using one of the cheap Radio Shack phone polarity on various phone outlets in my house and ended up plugging it into my IAXY. While the regular phone jacks tested OK, the IAXY tested as being reverse polarity. The tester was plugged directly into the IAXY so there is no chance of this being caused by crossed wires. Is this something that is misconfigured on the IAXY, a hardware
