Hi I am using a GSM mobile SIM router to host my IP-PBX using Raspberry Pi 4. System works fine internally within the SIM router. But when remote extension trying to log in to my IP-PBX, that's where problem starts. After digging, only to realized that WAN IP for my SIM data provider has multiple LAN IP. My mobile SIM router is given a LAN IP and a shared GSM WAN IP instead of dedicated one, therefor inbound traffic is not available. I need something like. OpenVPN sits in the middle between my remote extension and my IP-PBX. OpenVPN comes with a dedicated WAN IP where my remote extension and my IP-PBX can report to. Inside OpenVPN, OpenVPN would be able to connect them together using LAN IP. Scenario would be, 1. IP-PBX log on to OpenVPN using OpenVPN dedica...

I am trying to explore the possibilities of installing a SIP server or SIP GSM Gateway into an android phone. Using a remote sip client, the sip server would be able to authenticate remote sip client using username and password. Once authenticated, when sip client request a call out. Sip server will trigger a call out using the android’s SIM card. Or Android SIP server will report itself to a VoIP switch like asterisk. SIP client will also be connected to asterisk. When there is a request to call out from SIP client via asterisk. Asterisk will treat sip server as a trunk and thus making an outbound call using sip server’s SIM card.
