Re: [sr-dev] [kamailio/kamailio] pua: different behavior depending on db_mode (#2414)

Ok. Then it should be this one. https://tools.ietf.org/html/rfc3903#section-8.2 The ``SIP-If-Match`` is missing from any PUBLISH. pua is not doing the same depending on db_mode. Even if ``etag`` is not set we need to search for previous record. OK, first PUBLISH will never have a record but the rest yes. So, with db_mode == 0: First PUBLISH ``` PUBLISH sip:testuser1002@spce.test SIP/2.0 Via: SIP/2.0/UDP 127.0.0.1:5062;branch=z9hG4bK5b55.aee12144000000000000000000000000.0 To: <sip:testuser1002@spce.test> From: <sip:testuser1002@spce.test>;tag=40bd18ec79e1d8f7e9c3f54805d1ecb3-441aa447 CSeq: 10 PUBLISH Call-ID: 3cce05ee326f0119-24523(a)127.0.0.1 Content-Length: 577 User-Agent: Sipwise NGCP Proxy 8.X Max-Forwards: 70 Event: dialog Expires: 23761 Content-Type: application/dialog-info+xml <?xml version="1.0"?> <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="0" state="full" entity="sip:testuser1002@spce.test"> <dialog id=&quot;NGCP%invite_shared_line%///1-26774(a)127.126.0.1&quot;
