I’ve found the chan-sebi project, that is a very interesting way to create cellular client trunks. But it works only on Asterisk 1.4. Is there a port to 1.6 or any other solution for this other than chan_mobile?
You will need to modify the source to make it work for 1.6. Below is the diff file which you can apply to existing code:
