Hi, I'm looking for an 8+ FXS ATA gateway (at least 8 ports but preferably at most 24 ports) with 2 ethernet interfaces for network/switch redundancy. So far I've only found the Grandstream GXW4008. I've searched similar brands such as Linksys and higher-end brands such as Quintum, but they all seem to have just one NIC. So, if the switch the ATA is connected to fails then I'm out of business (at least until I replace the switch but that's usually too long for a busy system). Th...

Hi, Has anyone compared SPA8000 vs. GXW4008 especially in terms of firmware and hardware stability (the feature sets are apparently similar)? Vieri

I realize this may be slightly off-topic but I'm wondering if someone here can lend me a hand. One of my GXW4008 has gone "unconfigurable" via standard HTTP (refuses connection) and I can't use the built-in IVR because I had previously disabled the "keypad update" feature. So I'm stuck with just telnet, the reset button and RS-232. Telnet commands are very limited and I can't...

Hi, I have a set of Grandstream GXW4008 (units of 8 FXS ATAs) and another set of Linksys SPA8000 (8 FXS ATAs). The GXW4008 has a "neat feature" called "early dial" which allows me to define a "dial pattern" as generic as {*X+,#+,X+} (or something similar; the idea is to "match all digits") and sen...

...ns_pkt: Hanging up call 954539948-5060-2 at 192.168.1.100 - no reply to our critical packet (see doc/sip-retransmit.txt). I read about SIP-packets being retransmitted but in the end not being acknowledged and so Asterisk ends the call. The network is like this : analogue phone -- Grandstream GXW4008 -- Linksys WAG160 -- Asterisk server -- ITSP Is this a NAT-problem in the router ?? Can it be resolved ?

Hello All, I am trying to setup a small system where Nextone Softswitch will send traffic to Asterisk and then terminate on Grandstream GXW410x IP Analog Gateway but for some odd reasons the call are flashed back from Grandstream to Asterisk and creating a Black loop... I did follow the instructions provided by Grandstream support but it doesn't seems to be working...

I have an Asterisk running with both GXW4008 (FXS) and GXW4108 (FXO). The FXS Gateway works perfectly, no problem so far. The FXO Gateway (GXW4108) also works fine. The configuration for local settings in Brazil was quite easy, however, I still not able to make Caller ID to work. I'm setting as DTMF Caller ID type, but still not working....

Hello, Is there any reason why an IP-phone would pounder on port 5060 ? My firewall blocks the public IP because it thinks the remote IP is port scanning on port 5060. I think the phone is just registering but for some reason it does this repeatedly in a very short time.
