I have just joined in the past couple of days and want to say this appears to be an excellent service. Congrats.

Now to my questions - forgive me if I am duplicating questions but although I have read all I can find I am still not sure.

If my son takes my ATA device with him on a working holiday to say the US or Australia, can he just plug in the unit to a router and be able to use the device as if he were at home (allowing for firewall settings etc)?

Is there any time limit on how long he may continue to use the 076 number from another country?

When setting up the device, I had to select 'random ports'. I would like to fine tune the firewall settings and need to know what range of ports is needed, please.

I saw mention of capability of receiving more than one call at a time. If I attach more than one phone to the ATA can I answer the first call on one phone and the second on the other? Is there a limit, besides bandwidth, to the number of calls that can be simultaneously received?

I apologise if this post is in the wrong area.

Thank you for your attention.

correct

No

There are a number of ports used for communication. Normally the problem is with access for INBOUND communication. That means the ports on your device.
If you are using port forwarding you need to make sure the following ports are forwarded. Please remember these are set on YOUR device, you need to check local settings.

SIP (UDP): Normal default 5060 (this is used for call control)
RTP (UDP): Normal range 5000-2000 (This is used for media ie.voice)
*I underline again that these will vary based on you local settings (CHECK YOUR ATA SETTINGS). RTP is utilised in odd/even pairs so minimum you need to open 2 ports.

Yes, and make a call on the third

>Is there a limit, besides bandwidth, to the number >of calls that can be simultaneously received?

No (well not one you should be worried about), bandwidth will be your limitation and quality of your broadband.

Thank you very much for the replies.
I have one further question if I may:-

You specified port 5000-2000

If this were a range I would have expected the lower port first, and if just two ports I would have expected a comma between them. So I just need clarification please - does this mean all ports between 2,000 and 5,000?

Thank you again for your quick response to my questions.

range 5000-20000

but check configuration on you local ATA, it should let you pick start and end port.
