Hi! I have an issue with an Asterisk behind Kamailio when using the res\_pjsip\_path module. My intention is that Asterisk stores the Path information on the Contact from the REGISTER message, and when a call is created to that contact, it will also send that Path information so the proxy can route the message accordingly. The issue is that Asterisk is not sending that back on an INVITE to the contact. Below the messages: The REGISTER that is okayed: ```auto 2021/03/24 15:18:00.974575 10.158.15.239:5080 -> 10.34.0.130:5080 REGISTER sip:asterisk-pabx-0002:5080 SIP/2.0 Via: SIP/2.0/UDP 10.158.15.239:5080;branch=z9hG4bK055b.ec45c9bc1bb8be0754621cd87c4f2c6f.0 Via: SIP/2.0/WSS 14r83na1gc83.invalid;rport=51717;received=177.xxx.xxx.xx;branch=z9hG4bK4344189 To: From: ;tag=ntj9v5cevo CSeq: 3 REGISTER Call-ID: 8dbf08msdlji3ad9ai4n Max-Forwards: 69 Authorization: Digest algorithm=MD5, ......... iiff6d", nc=00000001 Contact: ;expires=600 Allow: ACK,CANCEL,INVITE,MESSAGE,BYE,OPTIONS,INFO,NOTIFY,REFER Supported: outbound, path, gruu User-Agent: SIP.js/0.17.1 Content-Length: 0 Path: Path: ``` INVITE: ```auto 2021/03/24 15:19:09.720938 10.34.0.130:5080 -> 10.158.15.239:5080 INVITE sip:0835h32r@10.158.15.239:5080 SIP/2.0 Via: SIP/2.0/UDP 10.158.0.36:5080;rport;branch=z9hG4bKPj63efe1d9-93c9-4b7d-8535-4f9010f5b971 From: "User" ;tag=5422bfc8-e1d8-49fe-bc04-6ce153d4b754 To: Contact: Call-ID: 7ad68fe2-4006-43a9-9f93-13d78550b725 CSeq: 7968 INVITE Allow: OPTIONS, REGISTER, SUBSCRIBE, NOTIFY, PUBLISH, INVITE, ACK, BYE, CANCEL, UPDATE, PRACK, MESSAGE, REFER Supported: 100rel, timer, replaces, norefersub Session-Expires: 1800 Min-SE: 90 Max-Forwards: 70 User-Agent: Asterisk PBX 17.6.0 Content-Type: application/sdp Content-Length: 901 v=0 o=- 129955850 129955850 IN IP4 10.34.0.130 s=Asterisk c=IN IP4 10.34.0.130 t=0 0 a=msid-semantic:WMS * a=group:BUNDLE audio-0 m=audio 26240 UDP/TLS/RTP/SAVPF 107 8 0 9 101 a=connection:new a=setup:actpass a=fingerprint:SHA-256 2F:94:09:A9:71:30:05:04:5C:50:56:CA:C1:51:44:4B:A6:28:9B:69:29:87:8D:7B:52:6E:56:37:CD:45:37:32 a=ice-ufrag:4e126cfa1816a77c445dae9d6fadc1ae a=ice-pwd:54aac5346a24c5d21cedb0b536f8ec5d a=candidate:Ha220082 1 UDP 2130706431 10.34.0.130 26240 typ host a=rtpmap:107 opus/48000/2 a=fmtp:107 useinbandfec=1 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:9 G722/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 a=maxptime:20 a=sendrecv a=rtcp-mux a=ssrc:484386811 cname:71933c1a-d697-4080-8cba-123971794c8e a=msid:7e90bf6f-08dd-4fb9-8162-81855b03bfb7 52535d77-c7ac-47b4-87c5-52d702ae316a a=rtcp-fb:* transport-cc a=mid:audio-0 ``` Any ideas?

How are you dialing the endpoint in the dialplan? I ask because there is an open issue[1]. [1] [[ASTERISK-28211] chan\_pjsip: Path header is not used with PJSIP\_DIAL\_CONTACTS - Digium/Asterisk JIRA](https://issues.asterisk.org/jira/browse/ASTERISK-28211) ---

Hi @jcolp , thanks for the fast answer. I’m not calling using the Dial application. There is an external INVITE from another extension calling to a queue, where that other extension is a part of. It seems that bug is only related to a call start via the dialplan application, correct? ---

Yes, but you’d need to state how the agent is called from the queue. You’re also running a security fix only version of Asterisk, so things may have changed since too. ---

Hello, Asterisk need knows Kamailio support Path Protocol. My Kamailio configuration: _append\_hf(“Supported: path\r\n”);_ _add\_path();_ _rewritehostport(“IPAsterisk:5060”);_ _forward();_ Regards ---

Awesome! Thanks for the feedback. Will try that header and will also try to update Asterisk to 18. Will share the findings. ---

> [@annusfictus](#): > > append\_hf(“Supported: path\r\n”); This added the Header in the request, but Asterisk is still not sending that back on the INVITE. Is there any way to see in Asterisk if the path was stored? ---

It is stored with the Contact, by default that is in the Asterisk database and can be viewed in its entirety using “database show”. ---

Cool. Did not know that command! Thanks! Looks like Asterisk is saving it: ```auto /registrar/contact/1002;@d43974c7dc9f6364db26b717614d6cb9: {"via_addr":"ftopddmia60r.invalid","qualify_timeout":"3.000000","call_id":"pfsenii6fer2kcb2sc6d","reg_server":"","prune_on_boot":"no","path":",","endpoint":"1002","via_port":"0","authenticate_qualify":"no","uri":"sip:5ttva8f9@10.158.15.239:5080;x-ast-orig-host=ftopddmia60r.invalid:0","qualify_frequency":"0","user_agent":"SIP.js/0.17.1","expiration_time":"1616605504","outbound_proxy":""} /registrar/contact/1003;@140ff2098e288e1f639a25828798e7dd: {"via_addr":"isg9fis99pro.invalid","qualify_timeout":"3.000000","call_id":"jpi8kmorsi7q5t3nr4p2","reg_server":"","prune_on_boot":"no","path":",","endpoint":"1003","via_port":"0","authenticate_qualify":"no","uri":"sip:3ss93ud5@10.158.15.239:5080;x-ast-orig-host=isg9fis99pro.invalid:0","qualify_frequency":"0","user_agent":"SIP.js/0.17.1","expiration_time":"1616605503","outbound_proxy":""} ``` Maybe it is something in the contact that is not matching? The queue I’m dialing to test this is configured like: ```auto [queue_template](!) musicclass=default strategy=ringall joinempty=yes leavewhenempty=no ringinuse=no [allext](queue_template) member => PJSIP/1002,0 member => PJSIP/1003,0 ``` ---

I would expect it to be present in the INVITE given that configuration. I do not know why it is not. ---

Will give Asterisk 18 a try then. ---

Hello, I tested on Asterisk 13 but not on 16 or 18. To be sure this is not a bug, call directly PJSIP extension from another PJSIP extensión and look if situation change. Regards ---

Calling directly to the extension yields the same results. Going back to an unsupported version is really not an option tough. ---
