[Asterisk-Users] ACT Gateways

[Alex Barnes]

Hi,

We choose the Mediatrix 2102 with 2 analogue and 2 ethernet ports.

Cost: £89.99 (roughly equiv $165).

We are using these to hook up Faxes and DECT phones (cordless).
The top of the range business DECT from from BT is £30 (if you buy a few from trade).
Worth mentioning that even VoiceMail indication works on the BT analogue phone.  Also the voice quality was actually better on the top of the range business DECT phone than the top of the range home BT phone which retails at around £90 (the one that includes SMS / mobile sim card support).

What other cordless choices are there for native SIP phones???

Zyxel Prestige 2000W Wireless SIP Phone = £159.99 (on sale even).


I think you can easily do the math and realise what the best option is.

HTH

Alex

just one example. my point was that as of this moment, ACT are more focussed on their phones and it may well be wise to look for gateways elsewhere for the time being, whereever that elsewhere may be.

I don't really understand the obsession with FXS devices.

The only uses I see for FXS are

- connect a FAX machine, where FAX may not be the best application for VoIP anyway,
- connect an existing cordless phone, where you probably have only one such device and a Grandstream HT286 will just do fine,
- connect the analog phone in a hotel to a travel adapter, IAXy would seem to be the best choice here because you are so much more likely to encounter NAT traversal problems and other obstacles that you may not be able to resolve with a SIP device,
- feed some Internet based phone services into a legacy PBX that wants to see them as CO lines, here again, depending on the number of feeds, HT286 may be cheap and cheerful enough.

For anything else IP phones should be the default with no buts and no ifs. I am always puzzled by how people desperately hang on to legacy stuff they don't really need and in the process create a beast of a kludge technology. The x86 architecture (or lack thereof) should be an example that serves to show how not to design your stuff with legacy support as your all-overriding number one priority. So, let's not make the same mistake with VoIP. Let's get rid of analog phones as fast and forcefully as we possibly can.

In other words, FXS should be the very very last resort when there is really no other way.

Having said that, I notice that Yoda have a 4 port FXO gateway (VG400), or at least it can be configured to be a 4 port FXO gateway. Now, that is rather interesting. Do you have any idea how much this device costs (ballpark figure wise) and how well it can adapt to PSTNs in other countries?
