Keep-alive to the SIP server is not working

Asterisk Asterisk SIP
1

Hi,

I am using Asterisk 13 with PJSIP. I have defined my general section in pjsip as follow:

[global]
type=global
keep_alive_interval=20
endpoint_identifier_order=username,ip,anonymous

I used tcpdump and wireshark to see the keep-alive packets and do not see the keep-alive working properly.

No matter what I defined “keep_alive_interval=” to, it is always sending the signal every 30 secs instead of defined time in the “keep_alive_interval=”.

How can I send the keep-alive packets to the sip server so the communication tunnel will be always open?
I want to make the keep-alive interval 5 secs but doing “keep_alive_interval=5” is not working.

Any help would be appreciated.

Thanks.

Are you tracing keep alive packages packages for UDP or TCP connection and also have you read this post http://forums.asterisk.org/viewtopic.php?f=1&t=95303 ?
