<div dir="ltr"><div><div><div>Another update. Thanks to awesome work by Terry Gillett, I have the same thing working now just on a tiny AR150 wireless router. This means, among other things:<br></div>1. You can have a WiFi+GSM telephone network just with mesh nodes - no schoolserver needed.<br></div>2. If you have a schoolserver, you can benefit from the additional features like voice mailbox. However, you need not have the dongle plugged into the schoolserver anymore. the dongle can be plugged into a mesh node which can be far away from the schoolserver, and there will be an asterisk trunk (over WiFi) between that mesh node and the schoolserver. This is useful since in a village community that doesnt have mobile connectivity, you would typically place the schoolserver centrally in the village, while the mesh nodes which are physically, and power-footprint wise tiny, and much more durable (in terms of temperatures they can handle) can be far away (in an area where there is GSM connectivity).<br><br></div>We are still doing multiple tests around this to figure out quality of service, etc., but the PoC works. <br><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Feb 11, 2017 at 9:33 PM, Tim Moody <span dir="ltr"><<a href="mailto:tim@timmoody.com" target="_blank">tim@timmoody.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Very impressive.

So far, I set up asterisk on the schoolserver to run a SIP telephony service on the wifi network where people can call each other. <br><br></div>Last night, I connected and configured a gsm modem (only specific huawei models work) to act as a bridge between SIP and GSM networks. Now, someone on the WiFi network can place outbound GSM calls. Someone on the GSM network side can call the dongle's SIM's phone number and be presented with an IVR where they can dial the extension of the user they want to connect to.<br><br></div>If any of this is potentially useful to your deployments, please get in touch. <br><br></div>This is going to be super-duper useful for the deployments in Spiti and Ladakh<div><div><div><div><div><div class="m_-6756934870614332977m_7662101228283751164gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><br><br></div></div></div>
