Hi,
I'm looking for a ATA device which supports multiple SIP accounts. I intend to use one for domestic and 2 others for international calls.

I have a cable connection and Linksys WRT54G WIFI router. Not sure yet if I will keep existing phone line or go to VOIP completely.

I'm considering Linksys SPA 3000 ($134.00). Is that a good choice? Can you recommend other options?

Thanks a lot!

If you really wanted to save money, you could buy the PAP2 - one of the cheapest and best value-for-money ATAs around. You then open a VoXaLot account and register several VSPs on the account. Think of the PAP2 as a single power point, and your VoXaLot account as the 4-way (or indeed 40-way) powerboard into which you can plug all these different VSPs (SIP accounts).

I'm afraid configuring VoXaLot account adds complexity to the overall setup and adds additional point of failure. Just as everyone else who never tried VOIP I'm concerned about quality, reliability etc.
Sure I can save $40 or so on a simple device... but what if VoXaLot will introduce account usage fees next month?

Just get another thought: maybe I should buy all-in-one VOIP device and router, and sell my existing Linksys WRT54G? Is there a benefit in having QoS or other features of all-in-one devices?

I used SPA3000 for over a year and have now switched to SPA3102. Cannot go wrong with these devices. Good value for money. Go for a SPA 3102 and you wont regret the choice.....

I agree with Thanee,

SPA-3000 or SPA-3102.

You can configure multiple outbound providers, but you can only have one incoming provider. Also has the PSTN backup

or if you only want two providers and no PSTN

SPA-1001 would be a good choice. Can do two providers back to the one handset.

Configuring VoXaLot is no more difficult than configuring your ATA. It has extra advantages over your ATA in that it can perform ENUM lookup and can receive calls from other customers of the various VSPs registered within Voxalot.

Just as everyone else who never tried VOIP I'm concerned about quality, reliability etc.

I can assure you that VoXaLot is very reliable. Their uptime is 99.9%.

but what if VoXaLot will introduce account usage fees next month?

VoXaLot's Martin B has stated many times that the basic VoXaLot functions will remain free. A premium account with extra features will be introduced in the near future.

Oooops, not good! This is exactly what I want! I want to have 1 incoming local number in Australia and another one (or even two) overseas so my friends and family can call me on their local rate. The overseas numbers are not a direct numbers but rather a gateways located overseas.

I'm reading user guide and specs for SPA-3000 but can't see where this limitation is mentioned.
www.sipura.com/support/index.htm
example, datasheet says:
VoIP to PSTN routing features:
*Voip Caller PIN and Associated dial plan - up to 8

Regarding SPA-3102, not sure why it's any better for me. I already have wireless router WRT-54G, why do I need another router?

You can only have incoming calls on SIP accounts which are registered. The SPA3000 has only one line where you can register an account. (The registration for the PSTN Line is not for receiving incoming calls.) The gateways are only for outgoing calls.

VoXaLot will give you the ability to register multiple VSPs and therefore receive incoming calls from multiple providers. There are exceptions though - you cannot receive calls on MNF and Freshtel accounts and I'm sure there are more. However MNF is looking into the issue.

Hi all,
I stumbled on this thread while looking for what's on the market today.
Myself I have a Fritz!box 7050 ADSL router installed at my place here in Erope.
This is really the most fantastic voip device on the market, since you can make dialling rules, multiple sip accounts (incoming and outgoing) etc.
It is of German origin, and if one of you guys decide to get it, watch out for one thing: there's 2 versions on the market. One is the standard version for the German market meant for Annex B phonelines, and an intl version for Annex A lines.
I dunno what you guys downunder have, but its something to keep in mind.

Thanks for the voxalot tip!

Hi Everyone,

I am new to VoIP world and have a question regarding the use of an ATA with multiple SIP accounts.

I have a SIPURA SPA3000. It seems there is only one place under the SIP tab that the RTP Packet Size can be set. Different VSP may have different packet sizes e.g. 20ms, 30ms, 40ms.

So now if my Line1 VSP requires a 20ms voice packet size, but other VSPs I use as Gateway1, Gateway2,etc. require say 30ms, will I have problems please.

Cheers,
Mike

I have been using VoIP for 24 months and at the same time using about 6 VSP's simultaneously and have never seen an instance where a VSP has specified a voice packet size.

MNF spec 40mS in an email sent to you after joining.

Hi Max,

I intend to use HK2B (an overseas provider) which uses 20ms, and someone told me this setting is crucial for outgoing calls out from HK2B.
