Hello linphone developers group
I'm seeing a strange behavior in the S5 phone (192.168.11.5) ; vpn is enabled ( tested both manual and automatic mode), run the sip client application, and it registers, Established a sip call and saw that on S5 all the audio is going through the non vpn interface (un encrypted) while all other date is going over the vpn interface.
when using other phone (sip2.pcap file) it seems that all data (sip, rtp and h264) is going over the vpn tunnel, it is observed that while the S5 (kit kat) is indicating in the sip header its via address 192.168.111.x the other is doing right and goes through the vpn tunnel 192.168.165.y
Sip5.pcap message 18 the via header in S5 indicating 192.168.111.4 in the via header while , the other phone indicates normal or no via header for example message 68 in the same file.
1. When I disable the vpn, the s5 audio is working well,
2. When I enable h264 video and then disable it, audio starts working.(sip1.pcap)
3. I changed the forwarding routing rule for vpn 0.0.0.0/0
and it didn't solved the it.
