Folks

I currently run a Sipura SPA1001 ATA through a Belkin wireless router.

Is there any reason why I could not run an additional ATA (probably
another SPA1001) through a spare Ethernet port on that router to allow
a someone else to run their own phone line (my daughter ..... she can
take it with her when she leaves home to go to Uni).

Regards

Mick

Shouldn't be a problem, but if you only have one public IP address then
obviously you won't be able to forward the same ports to two different ATAs
[if indeed your setup did require port forwarding to get it working].

Port forwarding issues?

Presumably you already have certain ports forwarded to you SPA1001, or
it's in the DMZ?

You would need to change default ports to something else on the 2nd
device, perhaps - unless you have a router whose firmware can handle
SIP/RTP properly, without any forwarding.

Considering the points that Jono has raised then that might also be a
problem  when your daughter's phone is connected up at Uni.
I would think that you would have to go and set it up. You'd have to
be lucky that it would work first off on current settings. Some
Universities may block ports anyway. If that happens you may have to
consider using your VSP account via  a service that allows use of
different ports.

This is interesting.  I have always thought of my PAP2 as two ATA's
in one box, but clearly there is more to it than that. So what is the
internal arcutecture of a PAP2?

It certainly has two independent VoIP ports - and these can be registered
with two different VoIP suppliers if desired. But it's still a single
device - with only one IP address - as far as your LAN is concerned.

However, if it's anything like the SPA2100, Line two's SIP port
defaults to 5061.

There is honestly no need to forward ports for any SIP device nowadays.
Any SIP provider with even half a brain will cope fine with devices
behind a NAT.

I've been using SIP devices for 5 years now.  I certainly haven't put in
a single port forwarding for SIP in the last 3 years.  It just isn't
necessary anymore.

It is 2 ATAs in one box.  The listen on different port numbers.

No problem at all, I have about three hanging off a Fritz!Box here (Which
has 6 accounts all by itself..!)

Make sure you assign fixed IP addresses to them though, DHCP causes
problems.
