SIP ATA with 4-32 FXS ports for IPO Office

[Albus2]

Hi

What is your recommendation for SIP ATA's with more than 2 ports?
4-port
8-port
larger

Some criteria:
- works with IP Office
- for fax, door system, special device, etc. but also for simple analog phones.
- shall *not* behave like a PBX, SBC, Firewall, etc. and if then it shall be possible to disable this.
- anything dialed goes to the IPO, i.e. no (or disabled) dial rules and manipulation. IPO is the PBX, not the ATA
- possible to save and restore the config
- possible to have a config as a template, i.e. based on a known-good config, we can just change the individual values like IP, Port, EXTN, Password
- affordable
- available. Not End of Sale, old version, etc.

Does such a device exist?

I like the Grandstream. devices, centrally managed never caused us any trouble. One thing to note the I cant get the Message Waiting notification to work (with nay ATA) but I think its an IPO limitation it doesn't appear to send any sort of SIP notification for this. If anyone can prove me wrong, I would be very happy.

Only use a 2 port Grandstream HT812 but they do have 4 and 8 port models.

It does use * commands so you may want to check with conflicts with the IP Office and amend the dial plan. You'll probably find the same with other ATAs.

There's a free device management which could be useful.

Basically any quality ata ahould work, I normally use Huawei IAD, Dinstar DAG, Yeastar TA and Grandstream FXS gateways.
What is your reason for wanting to use FXS gateway on IPO?. Are the IPO FXS cards more expensive than the FXS Gateways? or its to conviniently cut costs on cabling by making use of the LAN and cut cabling distances to different locations.

Good point Wanet. ATAs will need a third party IP phone licence which isn't cheap. I think Avaya priced it this way to discourage using other vendors' phones.

@ipohead . Unless he has several proprietary sets of avaya on his system, it may be wise to just replace the system which one that supports SIP without licenses to use third-party devices - e.g Yeastar, Grandstream (Both based on Asterisk). If budjet isn't a big issue he can proceed.

AudioCodes MP-124s have 24 ports and are fairly reasonably priced. You can jump up to a MP-1288 which has anywhere between 72 and 288 FXS ports. Those are not inexpensive.

You can make the config ugly and use a SIP trunk to connect the AudioCodes gateways to the Avaya system, but that goes against your 'gateway shall not operate as a PBX' requirement. I've used that type of connection for ringdown phones, fax machines, etc.

I've been using Grandstream devices for the past 20 years. They are inexpensive and their product support seems to be better than others.

the one thing that I've been wanting with them is for PoE capability - I hear that it's under development. They have it available on the 841/881 devices, but they are multiple ports of FXO with only one FSX port

Their current product lineup for ATA's and Gateways:
HT812 v2 - this is a 2 port ATA with 2 port NAT router.
HT814 v2 - this is a 4 port ATA with 2 port NAT router.
HT818 v2 - 8-port ATA with 2 port NAT router

Like all previous Grandstream ATA's that have a 2-port NAT router, the WAN port is a DHCP client - this is what I connect to the customer's network. The LAN port on the Grandstream by default has DHCP enabled. I usually cover this port along with disabling DHCP
I usually access the GS by the IP address on the WAN port, but I've sometimes needed to directly connect to the LAN port. I'll give my laptop 192.168.2.5 and then connect to the LAN port and browse to 192.168.2.1


Grandstream also has their GXW series Gateways.
These are 16/24/32 and 48 port Gateways.
One Ethernet connection to the LAN.
These all have 50-pin Amphenol connectors on the back to be cabled to an MDF with a 25-pair cable.
The 16, 24, and 32 port units also have RJ11 ports on the front to make it easy to "Patch" over to a patch panel. I wish they were RJ-45 connectors (less confusion to non-Telephone people), but the RJ11s can plug into patch panels too.


I've used Adtran, Cisco, Zyxel, MultiTech and others since discovering SIP ATA's in about 2004 (I've worked on telephone systems since 1997). I find the Grandstreams the easiest to configure and maintain. And each time they come out with a newer model or firmware, it's almost always been an improvement over their past devices.

I hope this helps.

I've used the 24-port versions of the AudioCodes and Grandstream ATA's with a 3rd party provider. We had difficulty doing 3-way calling with the AudioCodes. The documentation says it should work, but the provider couldn't get support from them, so we ended up swapping them for Grandstream ATA's. No issues with Grandstream. I use a bunch of their 2-port ATA's on my PBX (OpenScape Voice) and they're stupid simple with lots of features.
