Would you mind repeating the test with canreinvite=no set for all you phones and mobile phones? What is your upload bitrate? Is it guaranteed? I would try also to test the PMTU: Try: ping -M do -s 2000 ${ip address of the sip server} You should receive icmp asking for lowering the packet size. The LTE phones could have lower MTU and thus overcome PMTU problem. Marek 2020-06-22 21:48

Make all your tests, then: Well, assuming eth0 is the DSL interface and eth1 the phone interface, I can so that: tcpdump -i dsl0 -s 0 -w /tmp/test0.pcap host tel.t-online.de & tcpdump -i phone0 -s 0 -w /tmp/test1.pcap host 192.168.200.xx (IP of my phone) & is it correct?

Hi, I hope that someone could help me because I am a real newby in Samba and have a tons of questions about this apps.

I have 2 subnets in my company, the 205.205.247.0 is a windows segment with wins. the second one is 192.168.251.0 for the training classroom. The gateway where Samba is installed is used both as
