Thanks for the answer! Did I understand correctly that I need to install "kamailio-dbg"? I installed Kamailio via "apt install" from the repository. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/2970#issuecomment-1002095222 You are receiving this because you are subscribed to this thread.

I apologize, but the packages cannot install kamailio-dbg on Debian, the repositories do not have any kamailio-dbg, kamailio-debbug, kamailio-dbg. Maybe I need to include from the debbig module parameters https://www.kamailio.org/docs/modules/devel/modules/debugger.html? -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/2970#issuecomment-1002116799 You are receiving this because you are subscribed to this thread.

It seems that problem is not in contact parsing. I think that object are in failed some state In core dump we have what it seems to be a valid Contact field ``` #0 0x00007f0b29e26979 in fill_contact (ci=0x7fffff6755a0, m=0x7f0b2a68e780) at cmd.c:271 ``` ``` "<sip:alice@10.2.16.36:5060;gr=00F54E59-1172-EC11-9AC7-7D467C83D9C2> ---- INVITE sip:bob@ims.mnc001.mcc001.3gppnetwork.org SIP/2.0 Via: SIP/2.0/UDP 10.2.16.36:5060;branch=z9hG4bK8019dd952e72ec119bd47d467c83d9c2;rport From: "PhonerLite" <sip:alice@ims.mnc001.mcc001.3gppnetwork.org>;tag=4116302762 To: <sip:bob@ims.mnc001.mcc001.3gppnetwork.org> Call-ID: 8019DD95-2E72-EC11-9BD3-7D467C83D9C2(a)10.2.16.36 CSeq: 1 INVITE Contact: <sip:alice@10.2.16.36:5060;gr=00F54E59-1172-EC11-9AC7-7D467C83D9C2> Content-Type: application/sdp Allow: INVITE, ACK, BYE, CANCEL, INFO, MESSAGE, NOTIFY, OPTIONS, REFER, UPDATE, PRACK Max-Forwards: 69 Supported: 100rel, replaces, from-change, gruu User-Agent: PhonerLite/2.97 P-Preferred-Identity: <sip:alice@ims.mnc001.mcc001.3gppnetwork.org> Content-Length: 340 ``` We have normal pointer to parsed object but object itself contains garbage. This is why no parsing is performed and [this](https://github.com/kamailio/kamailio/blob/master/src/modules/ims_ipse… check passes. ``` (gdb) p req->contact.parsed $45 = (void *) 0x7f0b2a69b778 (gdb) p *(contact_body_t*)req->contact.parsed $46 = { star = 3 '\003', <---- this contacts = 0x38 <---- and this } ``` If we take ```next``` header than the ```parsed``` pointer will contain even stranger things ``` (gdb) p *req->contact.next $49 = { type = HDR_CONTENTTYPE_T, name = { s = 0x7f0b238ab6c3 "Content-Type: application/sdp\r\nAllow: INVITE, ACK, BYE, CANCEL, INFO, MESSAGE, NOTIFY, OPTIONS, REFER, UPDATE, PRACK\r\nMax-Forwards: 69\r\nSupported: 100rel, replaces, from-change, gruu\r\nUser-Agent: Phon"..., len = 12 }, body = { s = 0x7f0b238ab6d1 "application/sdp\r\nAllow: INVITE, ACK, BYE, CANCEL, INFO, MESSAGE, NOTIFY, OPTIONS, REFER, UPDATE, PRACK\r\nMax-Forwards: 69\r\nSupported: 100rel, replaces, from-change, gruu\r\nUser-Agent: PhonerLite/2.97\r\nP"..., len = 15 }, len = 31, parsed = 0x30003, <------- this next = 0x7f0b238ac088 } ``` I am not much into this code and unfortunately I am unable to find where this values are set. Are messages reused or created from scratch each time? The ```m``` variable (reply message) that passed into this method seems to be ok by the way. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/2970#issuecomment-1011387980 You are receiving this because you commented.
