Re: [General] How to do P2P calls ?
Thank you Nate425 for the link. The Sipura instruction mention:
Similarly, if calling another SPA on it's line1, press
" uid_remote*ip_addr_remote*5060# "
Now this is in Sipura notation. Translated this would probably correspond to a SIP calling address:
uid_remote@ip_addr_remote:5060
But that's exactly where my questions start. Imagine two users connected with their Laptop to the internet via two different ISPs. User A wants to call user B directly. Would it be necessary for user B - in order to receive the call - to have an account defined on his softphone client? Or would it be possible to establish the contact without a separate account in the softphone? If the latter would be possible then it wouldn't make sense to add "uid_remote@" in front of the IP. Further, is it necessary to indicate the port in the address? Or, is the incomming SIP signal just looking for the next available SIP phone, or an incomming IAX signal for the IAX phone?
May be you can recognise from all this where I have difficulties to understand what exactly I have to do.

Thank you sokhapkin for your answer. Port forwarding has been set up. I know that Voip providers allow for free calls between customers. What I really am interested to try and see how it functions is to do it just without a voip provider. I did set up an account at DynDNS.org for not having to change the IP in the calling address each time after registering to the ISP. I'm just wandering what is required on the sending and receiving end to establish such a contact. Can you or anyone else help?
Thanks and regards MET |

If both users are behind the firewall and nat, then there is no way to setup the communication unless DMZ or port forwarding is active. It's always better to have some proxy or registrar server on public IP address to setup the communication between clients. Many VOIP providers allow free SIP/IAX calls between customers.

| How does in a IAX client (e.g. Idefisk) an account has to be defined and how have calls to be established to allow direct Peer to Peer contacts (without a Voip provider) between two users A and B with completely different URLs using DynDNS.org; e.g. from XXXX@UserA.DynDNS.org to YYYY@UserB.DynDNS.org, where both, UserA and UserB, are behind a router with Firewall and NAT? Thank you.
