I try to connect my android-handy using the CSipSimple-App with OpenVPN to my Asterisk-server, so that I can telephone with my internal telephones, as usual at home in the Lan.
Unfortunately, I do not hear the person at the iternal telephones. Strangely, they can hear me…
I really do not have any advice, because I can register with CSipSimple-App over OpenVPN at the Asterisk-server. The only problem is that I can not hear the the other side at the internal phone. Quite strange is that the announcement “Hello World” from the Asterisk-server I can hear…
The IPs I am using:
Cisco SPA504 Phone 1: 192.168.33.20
Cisco SPA504 Phone 2: 192.168.33.21
VPN-Server: 192.168.33.15 (10.8.0.1)
The extension 10 in the sip.conf is one of the Cisco-Phones and the extension 11 should be my handy over openVPN
Thanks a lot for your help and sorry for my bad English!
