Re: [General] How to do P2P calls ?
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 |

1 edit | 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.
