kamailio core request dropping - no reply
Hi, I am testing kamailio replies when an INVITE or another request arrives with lets say, "VIA" header missing.... The core drops the request. But, there is no reply for the originator (so it keep on resending the request...) Why? Uri

If there was no Via header, the recipient would have no way to know where to send the response.
OK understood. I tried with no "TO" header as well, and still no error reply.... Is there suppose to be a reply from core? On Tue, Jun 19, 2012 at 4:12 PM, Andrew Pogrebennyk < apogrebennyk@sipwise.com> wrote:

I think in such cases you get a "parse error" in the log. Do you? If yes, then Kamailio stops processing the packet and no reply is sent. Reda On Tue, Jun 19, 2012 at 7:10 PM, Uri Shacked <ushacked@gmail.com> wrote:

I do get the parse error. Still, I think that even if kamailio stoped processing the request, an error reply should be sent back the the request sender, no? Something like - 501 ??

Hello, there are some mandatory SIP headers, without them a sip reply cannot be built. One is Via as the SIP mandates to send the reply where the last Via address points to. In RFC3261, Via also carries the branch parameter that should be used to match the transaction. Cheers, Daniel On 6/20/12 6:56 AM, Uri Shacked wrote:

Hello, if the message processing gets to config file, there is a condition on sanity check (see sanity module) -- if that condition fails, a reply is sent. But if the processing does not get to config file, means that mandatory SIP message structure was not met - no reply can be built based on sip requirements.
