Hallo all: I am once again looking for an alternative to Skype for private usage. The easiest thing to do would be to install WhatsApp, but I am still resisting.
I installed Linphone at home on Linux, Windows 11 and Android, and besides the "normal" Linphone idiosyncrasies, it seems to work reasonably well. I then installed Linphone for a family member in a remote location via Microsoft Quick Assist (a kind of Remote Desktop) on a laptop and on a PC. Both of them failed to connect to the SIP server, I got a red warning triangle, but no reason whatsoever. That was surprising. Both SIP accounts (mine and for the other person) are [email protected]. I tried both locally at my place, and they both worked straight away. I compared all network settings between the local and the remote Linphone installations, and they looked the same. Under Windows, I installed Linphone using the same Chocolate Package as on my local Windows 11 PC. So I thought it might be a network problem at the other end. I got the user to install Linphone on an Android phone on the same remote network (same WLAN and router as the laptop), and that worked fine. This is no complex network, it is a normal residential Internet router. I tried enabling and disabling STUN (stun.linphone.org) and other such Linphone connection settings on both the remote laptop and PC to no avail. On both PC and laptop, the Windows Firewall asked the first time whether Linphone should be allowed to connect on private and public networks. I only allowed connections on the private network (same as at my place). I then made sure that the WLAN on the laptop and the LAN on the PC (both connected to the same router) were marked in Windows 10 als private networks, but the connection to the SIP account still did not work. I am guessing that the TLS connection to sip.linphone.org is established over TCP, and the direction is Linphone client -> SIP server sip.linphone.org. Therefore, there shouldn't be any problem for Linphone to connect to the SIP server, regardless of NAT, STUN, etc. Later on, when 2 clients want to connect directly for audio and video, there may be firewall or NAT traversal issues, but not for the first SIP account connection. Is that right? Or does the SIP server try to connect back to the SIP client immediately? I didn't enabled Linphone logging at the time, I found out about such an option later on. I will try the next time around. The trouble is, I do not have easy access to those remote PCs. If I leave logging turned on, will it fill the disk? Or does Linphone limit and/or rotate the log files somehow? In any case, I would say that the Linphone connection-handling implementation is not very fortunate. You shouldn't need to look in any log files to get some error indication about why a connection to the SIP server couldn't be established. Thanks in advance, rdiez _______________________________________________ Linphone-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/linphone-users
