1. I received notification of your call (in my case, both my landline phone and my smart mobile phone ring),

2. I could not hear anything on the other end.

3. I checked the phone handset and it said 'Talking' which means that as far as the phone is concerned, the 
call is still connected.

4. I worked out later that I had two instances of my ekiga.net account registered at the time you called. One 
was in the VoIP settings of my modem, and the other was the CSipSimple app on my smartphone.

5. I Eventually hung up the landline phone, and went and had a look at the smartphone. The app CSipSimple 
reported a missed call, and had a record of your call because it said 'Bret Busby'.

6. I was having a look at the record of the call, to try and work out what had happened. During this process, 
I fouled things up. It looks like I selected all call history, and then deleted them. So unfortunately, I am 
not able to comment on the details of the record of your call reported from CSipSimple.

Anyway, if you could advise what, if anything, shows in your event history, for that attempt, it would be 

No can do.

7. I would be interested to see if I need to change my SIP configuration or not, which means receiving a few 
calls in a row to test my landline phone and my smartphone.

A couple of things occurred to me about this, which I posted to the Linphone list (although, subsequent messages posted to that list, by other people, appear to indicate a lack of technical support for Linphone, by the developers).

The first, is that, when I called you, I was using the default settings for each of my applicable devices. In Ekiga, I had to change the device setting for the microphone, and I changed it to what I had set up for Skype. In Linphone, I was unable to find provision of an Echo Test Call facility, thjat both Ekiga and Skype provide, so that, in Ekiga and Skype, a user can check the functionality of the devices and their settings, and, find whether what the user has set up, actually works.

As there appears to be no provision of that, in Linphone, I have no way of testing and adjusting my device settings, to ensure that the devices are properly set up.

The second thing, is that when run ning each softphone software application for the first time, Skype and Ekiga, from memory, prompt for the setting up of a SIP account, so as to enable the user to make calls across the Internet. Linphone does not do this, and, instead, sets up a default SIP address, using the format <username>@<users_IP_address>, and, the IP address can, as is shown in my case, the IP address within the LAN, which I do not want to be published on the Internet.

I subsequently found that that default SIP address supposedly allows for cals within, and, only within, a LAN, and that, to call across the Internet, a SIP accopunt that needs to be otherwise set up, is required.

On the Linphone web site home page, on the left side, is a menu, with one option being free SIP account.

In clicking that, I was led through the procedure for setting up a SIP account hosted by Linphone.

It was not made clear that this is required, to make calls across the Internet.

And, it is not intuiotive, especially when Linphone automatically creates a default SIP address, which, would appear to be all that is required for making calls across the Internet.

The "Free SIP account" option in the menu on the Linphone web page, appears to be, without proceeding further with that option, by selecting the button, no more than information about the provision of that default SIP address.

So, I believe that Linphone has critical deficiencies in its interface and functionality.

Also, I note that, in two attempts to send Chat messages to Greg (Linphone to Ekiga), on each occasion, clicking on the <Send> button, caused Linphone to crash (and the messages to be lost and not sent).

Another curious thing; when I contacted Greg from Linphone (me using Linphone to call Greg at his Ekiga SIP address), whilst the call showed within Linphone, to have been successful, neither he nor I could hear each other for the duration of each call attempt (after the ringing stopped, there was silence, and, after 30s of silence, I terminated each call).

But, at the end of each of those unsuccesful calls, Greg could call me (Ekiga account to Linphone account), successfully, and we could successfully sustain a conversation, in each call thus made from Greg to me.

So, calling Linphone to Ekiga, does not work, and,
calling Ekiga to Linphone, does work, apparently.

As I said to Greg, in one (or more) of the conversations, whilst the concept of Linphone (especially, that it supposedly covers the operating system platforms that it is supposed to cover, including MS Windows, Linux, and, Apple Mac OSX), appears to be good, the Linphone people have alot more work to do, to make it usable, and, at present, other than using it for testing communications with other softphone provision, such as testing for calling between Linphone and Ekiga, I would not bother with it again, until it is shown to be working properly.
