Call drops at 32 seconds

[drincon739]

Need some assistance, please. Inbound call  Call drops at 32 seconds everytime

[Uzair Mahmud]

are you behind NAT?

also is your server IP 127.0.0.1 in /etc/kazoo/kamailio/local.cfg

Check out this article https://blog.opensips.org/2017/02/22/troubleshooting-missing-ack-in-sip/amp/

Then run a SIP trace to ensure the correct Record Route and Contact headers.

Finally, check /etc/kazoo/kamailio/local.cfg

If your IP address is still set to 0.0.0.0 or 127.0.0.1 then the Record Route header sent to the callee will be the same. This is the reason for the missing ACK and eventually the dropped call. Update your IP address to resolve.

So when i restarted I'm  running into this error:

[drincon739]

but Kamailio is running. 

 

[tkiziah]

sudo systemctl stop kamailio

sudo systemctl disable kamailio

sudo systemctl start kazoo-kamailio

sudo systemctl status kazoo-kamailio

[drincon739]

After running the above:

 

thias 

[tkiziah]

First, you want to completely disable the kamailio service, and enable kazoo-kamailio. Anytime that you interact with the kamailio you should be using kazoo-kamailio.

A reboot should fix this without spending to much time ontroubleshooting what is binding to the default ports.

Thank you for your patience tkiziah as I I'm a newbie with Kazoo. so after disabling and starting, I'm still running into the same issue of the call dropping at 32seconds

i have also tried a reboot and getting the same results

[drincon739]

any other suggestions on what it could be?

[Uzair Mahmud]

are you running your setup on lan or over the internet?

[drincon739]

over the internet.

Dear Bro,

the root reason of call drop after 32 second due to ACK Timeout.

i setup my system behind NAT, so i had to config on freeswitch module:

vars.xml

<X-PRE-PROCESS cmd="set" data="external_rtp_ip=IP NAT SERVER"/>   <X-PRE-PROCESS cmd="set" data="external_sip_ip=IP NAT SERVER"/>

 

good luck!

@thanhnn.ict you might want to look at putting those in the sipinterface_1.xml instead. Just in case you decide to run multiple SIP interfaces that may not use the same external IPs.
