Hello I have a problem about volte(401 Unauthorized). P-CSCF: 4(4467) INFO: rr [rr_mod.c:515]: pv_get_route_uri_f(): No route header present. 4(4467) INFO: ims_registrar_pcscf [sec_agree.c:296]: cscf_get_security_verify(): No sec urity-verify parameters found Can you help me see where the problem is？ Tips：About SQN, the SQN is the same at the beginning of the test (Open5GS, FOHSS), but when it is found that the sip registration fails, the SQN is inconsistent. If this situation is normal? If it is not normal, how to solve it? open5gs：v2.2.3 kamailio：5.3 Thanks! 本电子邮件（包括任何的附件）为本公司保密文件。本文件仅仅可为以上指定的收件人或公司使用，如果阁下非电子邮件所指定之收件人，那么阁下对该邮件部分或全部的泄漏、阅览、复印、变更、散布或对邮件内容的使用都是被严格禁止的。如果阁下接收了该错误传送的电子邮件，敬请阁下通过回复该邮件的方式立即通知寄件人，同时删除你所接收到的文本。 This e-mail may contain confidential and/or privileged information.
