[Sarp-users] Re: SIP NAT traversal (contribution)

[Andrew R. <an...@ra...>]

Hi,

Thanks for the offer. I'm not doing any of the work on the C++ version
except providing information on how things are working for me on the
Perl version. Unfortunately I'm not a programmer :-(. I will forward
your offer to Dylan who is doing this work though. (about time he let
the rest of us see some of his code anyway :-).

So to your original questions: firewall changes will NOT be required for
outgoing calls so long as any outgoing traffic from the SaRP server is
allowed. Incoming calls will require the SIP port (5060 by default) to
be accessible on the SaRP server. If the SaRP server has a real world IP
then this just means allowing that traffic through or if it uses a
private IP then forwarding anything on port 5060 to it. As for the RTP
traffic this should be fine so long as any traffic from the server is
allowed out or otherwise follow the same procedure for the ports listed
in your config file as for port 5060.

As for IPFreedom, I am not familiar with them so I can't comment. Could
you provide more information?

And lastly, as far as communication is concerned the best place to get
in touch would probably be simply using the SaRP mailing lists. I'll
have to add links to them directly on the homepage, but for now use the
Sourceforge pages. (email me directly if you have problems)

Regards,

Andrew Radke
