[AusNOG] 48 port SIP-Analog gateway vendor comparison

[Michael Diamond]

Hi Tim,

I agree with Greg – Grandstream’s ATA are pretty good – we ripped out all our old Cisco/Linksys/Sipura ATA’s some time ago and replaced them with Grandstream and all our echo issues went away. They now have a 2nd Australian distributor who can assist.

We also have had good success with the Epygi range – the new UI has made them a lot easier to configure than in the past and they are pretty much bulletproof once you get them up and running. They come in 24 port modules, but I am pretty sure you can put two of them in a single chassis to take you up to 48 ports.

Would discourage you to use Zultys unless you are looking for a UC PBX all-in-one and have a confident, experienced Zultys engineer on hand , I can’t see too many benefits using them as a gateway only.

Contact me off list if you want more info on your specific requirements.


Kind Regards

Hi Tim,

The Zultys PBX that I played with a long time ago was absolutely horrible – I can’t speak for their ATA’s.
Programming was all ass about and interface was extremely inconsistent.

We have had good experience with Patton – they are pricey but they are rock solid.
Both their BRI and PRI units have been great. The smaller PSTN ATA’s have always been reliable too.
They don’t appear to do a 48 port ATA – 32 ports appears to be the largest - http://www.patton.com/voip-router/sn4400/

Availability in Australia for Patton is hit and miss.

The other product that comes to mind is the Grandstream.
I haven’t played with them in years but back in the day their VoIP phones were Basic but OK.
They have a 48 port ATA - https://www.grandstream.com/index.php/products/ip-voice-telephony/enterprise-analog-gateways/gxw42xx

Hope this helps and gives you some options.

Greg

Hi All,

We have to deploy some 48 port SIP-Analog gateways and need to assess between vendors for total cost of ownership including:

  *   longevity
  *   maintainability
  *   availability of spares

A reseller is steering us in the direction of Zultys.

Would anyone care to offer opinions / alternatives?

Thanks for your attention.

 - Tim
