Hello
Here is what I have got using this command on linux server:
tcpdump -c 200 -pi eth0 -s0 -w sipdump host 62.221.34.30 and udp port 5060
Where 62.221.34.30 is my SIP provider
First is call with voice,and second is without voice
About SIP client - I am using Grandstream BudgeTone-200 and DrayTek VigorPhone 350
And I have this problem with all GSM providers.
Voice On
