picked me up a GOIP-1 and a RaspPi ZeroW

i got it working but i cant seem to make 2 Calls at once

even if its 1 call IN and 1 call OUT

even if its 2 CALLS in

if there is One other the other 1 caller goes to voicemail of the sim card.

thought sim cards allowed 2 calls at once... yet... i know if its on hold...

is that the issue'

do i need GO-IP for outgoing and VOIP Account from Skyetel for the inbound?​

I would be very surprised if you could handle 2 concurrent channels open at the same time on the SIM. I used to run a calling card company for a large country and we used SIM cards to bypass the exchange and had hundreds of SIMs ... one per active call.

so i do need to connect another goip or just connect it to a voip/sip in order to use it at the same time ok. still not bad at $0.0012 per minute inbound if i voip in & sim out
