they both handle echo suppression. The grandstream has a program that auto detects this and sets it up. The audio codes is primarily programmed using bootp while we have an auto provisioning system for the grandstream, we only use the audiocodes where we require hookflash.

One question - the two ATA devices (Grandstream & AudioCodes) are around the same price so could you give us some more info on why you would prefer the one over the other (besides the hook flash feature). Do they handle echo cancellation or do you deploy a separate solution for that? Thanks again for your help! On 09/03/2011 08:35 PM, Darcy wrote:

For cases where I require a hook flash I use the audio codes fxo gateways. I never tested it on the freeswitch, we have own ap we wrote to handle it, we were doing this before we discovered freeswitch. I know it works and it is quite reliable. If I get time later today, I will give it a try on a freeswitch.
Brand: AudioCodes Mfr's SKU: MP114/4O/SIP VoIP SIP Gateway, 4x FXO, 1x WAN, LBR Codecs,
Here are the options you have for using it. they have a variety of configurations, fxo/fxs combos a 4 port is in the 375 range.
Hook Flash Option [HookFlashOption] Supported hook-flash Transport Type (method by which hook-flash is sent and received). Valid options include: 0 = Hook-Flash indication isn’t sent (default) 1 = Send proprietary INFO message with Hook-Flash indication 4 = RFC 2833

Does this ata support picking up call waiting while in a call from the fxo? If it were to do that, I would get one right away. The Digium FXO card I have has problems doing this with freetdm.

Hi, for fxo's with the freeswitch I currently use:
Mfr's SKU: GXW4104 Brand: Grandstream 4 x FXO Gateway, 2 x LAN, 1 or 2 stage dialing, G.168 echo cancellation
They work exceptionally well, easy to configure and can be auto configured if you are into that, we are. You can also get an 8 port version. I pay 220 for the 4 port and 300 for the 8 port. I have quite a few of them deployed.

Thank you all for your replies.
Anthony, you reply has left me uncertain again. All of the ATA's listed here (wiki.freeswitch.org/wiki/Interop_List) seem to have some limitations and bugs which have to worked around.
Your reply suggests that buying a OpenVox A400P04 card (currently only $219 for 4 FXO's) would be more difficult to install and maintain that 4 ATA's. I would have thought that the FXS/FXO cards were engineered to work with Freeswitch/Asterisk etc. without limitations like caller-id not working or call-transfer not working as expected.
I can see the benefit of an ATA since I can add them on as needed with little or no hassle (except for the large power board to plug them all into:-)
I have only just got the SPA3102 receiving incoming calls and I am no expert in either solution but would have thought that a 4 port FXO card would be easier as it is made to purpose?
ps. the PAP2T seems to be one of the better Linksys ATA's from the list of features that work?
Thanks again for all your help and suggestions.

If you are doing FXO and you already have an ATA working that might be as good as you'll get. Its nice to not have to deal with TDM if you can help it and most analog ATA are cheap and effective and much less painful to deal with than analog cards.

One think you should consider also, is the FXO/FXS board that you will buy, you have to check compatibility with your server/pc.
For example openvox models A800P and A1200P has an issue with motherboard based on chipset H55 for example.

In the following order, most people usually recommend:
1. Sangoma 2. Diginum/OpenVox 3. Building your own Tormenta Zapatel Card (Only for serious engineering types of people) from COTS

Hi
As a new member of the forum, I am curious to know your experience with FXO/FXS cards.
I have a SPA3102 and have configured it to work with FS, but it feels a bit like I am trying to make a square peg fit a round hole. I am hoping to implement FS at a business which currently has 4 POTS lines and would prefer to use an internal IDE card for the job of integrating these phone lines into FreeSwitch.
Has anyone got some advice on which cards I should be looking at that just "work" with FS? What about echo cancellation - is that something I should just cater for or does it depend on the client situation? What about software cancellation?
This seems like one of those times when too much choice is a bad thing and I need some guidance on what has worked for you.
All advice would be greatly appreciated.
