Seems like in theory this could be solved by having your asterisk system connect the call. Then block all numbers on your phone except your system.

- walrus01 5y agoIt could, I'm not quite ready to take that step yet. Or I could use exclusively a SIP softphone (zoiper) on my android phone to connect directly to my asterisk system as an extension, and only accept calls on that, which would come from the incoming filter call flow. The downside of that is that phone calls wouldn't work when in very marginal data coverage/rural areas, since voip-over-LTE-data relies on a fairly solid and packet loss free network connection, and the additional battery drain of maintaining a persistent sip client-to-server session on the phone all the time. I do have several extensions set up in zoiper for other purposes but I don't keep it running all the time.
- Terry_Roll 5y agoCell companies using deep packet inspection to analyse data have been known to throttle voip calls to mobiles. I think the minimum std for voip is around 56k so you dont need much bandwidth, but data over mobile phone networks is typically a burst of data which is the opposite of landline networks. I could use freeswitch (asterisk rival) on 2.5g quite easily, but you really are at the mercy of a cell masts traffic management software, however in the android app store there are some apps which let you override the cell mast traffic management so you can remain attached to the cell mast of your choosing when you want to. That also helps you avoid being triangulated for location purposes. Voice to handset always had highest priority as traffic, then text and then data, but the last two may have changed priority in recent years.
