sorry, the mail was signed with a certificate, maybe thats why.
Here the original text:
my setup is the Linphone App on Nokia 7.1 connecting to an Asterisk SIP Server.
Incoming calls get dropped after 32 seconds each time.
Outgoing calls work just fine.
Some researched showed it could be the 200 ACK packet that is not received.
I´m monitored all packages on the firewall, I see 200 ACK from Linphone to the Asterisk but not from Asterisk to Linphone.
After 32 seconds I get a TCP Retransmission from Asterisk to Linphone followed by a BYE
As a Firewall we use Sonicwall. so I tried to turn off the SIP Transformation (SIP ALG) but it didn´t help unfortunately. Consistend NAT is enabled.
Do you guys have any hint to where to look further into? Running out of ideas (google results)
Thank you very much in advance.
