Subject: [Linphone-developers] Android Linphone app from GPlay and Dahua VTO2000A
 
Hello,

I need little help, because i dont know, where is problem with app for videophone Dahua VTO2000A. I have videophone Dahua VTO2000A and two android phones, one is Samsung J5 2016 model and other Lenovo A850. VTO2000A works as SIP server and registration works fine on both phones. But I have problem with calls, when I call from VTO2000A to Samsung J5, it works fine, but from VTO to Lenovo A850, its not working. I used Wireshark to see UDP stream and there is only INVITE message and no response from Lenovo A850. I also tried call from both phones to VTO but thats not working, even on Samsung J5. Below are logs from Wireshark. One is when I call from VTO to Lenovo A850 and other from Lenovo A850 to VTO.
Thank you.

Best Regards
Lukas
