Let me explain,
I have a
1.Raspberry pi installed asterisk.
2.Grandstream HT503 ATA 1FXO and 1FXS
3.GSM fixed wireless terminal
My set up is I connected the raspberry and Grandstream through LAN port ,before that i changed the Grandstream as a Router and connected the fxo and fxs port as witha lan and a phone
This setup I need implement to use in astersik in my car
hear Am facing a problem my sip extension for FXO and FXS registerd in asterisk but its always shows UNREACHABLE
I avoided the WAN port as i dont have any local area network and internet
I connected the Ethernet port with Raspberry only.
