<p class="MsoNormal">Hello.<o:p></o:p></p>

<p class="MsoNormal"><span lang="EN-US">First of all, I would like to thank you all your effort to develop and maintain this API as it’s being very useful to us for handling modem connections in our embedded devices.<br>
<br>
We are facing an issue with ModemManager 1.16.2 (libmm-glib) and RC7620 SIERRA modem.<br>
<br>
Sometimes, after starting a call to another SIM card device (mobile phone), the call gets into “terminated” state (seen by ModemManager) in the moment the call is accepted by the remote device, while it remains active at this remote point.<br>
<br>
The call state becomes “dialing”, then “ringing-out”, and finally “terminated” so there is no option to finish the call from ModemManager side as it’s seen as already terminated.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We managed to actually finish the call (remote side too) by the use of ”mm_modem_voice_hangup_all_sync” function (defined in mm-modem-voice.h), but it’s only available since ModemManager 1.12 Version.
<br>
<br>
Some of our devices are using other hardware and older versions of ModemManager (1.10) and we have never been able to reproduce this issue so we didn’t need to make use of “mm_modem_voice_hangup_all_sync” function.<br>
<br>
I would like to know if this issue has been already reported, and if so, if it has been resolved or if it’s related to the hardware we installed on our device or, on the other hand, if has something to do with the ModemManager version being used.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thank you very much for your help.<o:p></o:p></span></p>
