Hi,

We possess a code within Kamailio, which specifically handles malformed SIP responses. Below is the code snippet:

reply_route
Copy code
if(!sanity_check("17604", "6")) {
xlog("Malformed SIP response from $si:$sp\n");
drop;

Additionally, we have Kamailio drop request statistics as follows:

Command: kamctl stats | grep core:drop_requests
Output of the command: core:drop_requests = 5

My queries are:

1. Is the aforementioned "reply_route" related to the drop requests we are experiencing?
2. If it is not related, what could be the cause of the drop requests?
