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.

are you behind NAT?

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

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!
