Hi, Does anyone have any idea?
I can send the sip trace if needed. -- Regards, William Jin ________________________________ From: Users <users-boun...@lists.opensips.org> on behalf of William Jin <willi...@exetel.com.au> Sent: Tuesday, 2 June 2020 2:48 PM To: OpenSIPS users mailling list <users@lists.opensips.org> Subject: Re: [OpenSIPS-Users] Question about IP Transit Just additional info: A(v4) => opensips(v4/v6) => B(v6) => C(v6) - also working Does that mean if the B number is V6, I need to send the invite to the v6 IP of the opensips? Then the server should handle the ip transit from v6 to v4 again? -- Regards, William Jin ________________________________ From: Users <users-boun...@lists.opensips.org> on behalf of William Jin <willi...@exetel.com.au> Sent: Tuesday, 2 June 2020 2:07 PM To: OpenSIPS users mailling list <users@lists.opensips.org> Subject: [OpenSIPS-Users] Question about IP Transit Hi We are using opensips 2.4.6 at the moment. It's the apt standard(not nightly) repo of debian opensips -V version: opensips 2.4.6 (x86_64/linux) flags: STATS: On, DISABLE_NAGLE, USE_MCAST, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 poll method support: poll, epoll, sigio_rt, select. main.c compiled on with gcc 6.3.0 The situation is: Our sip server has both IPv4 and IPv6 addresses, it handles IP transit pretty well. Say if there is an incoming call from the gateway A (asterisk IPv4), it can do the IP transit to the destination number registered in IPv6 A(v4) <=> opensips(v4<=>v6) <=> B(v6) We are using $T_fr_inv_timeout to do call forwarding if no answer. The issue here is: when the B has a call forwarding setting and if the destination number, let's say C is v4, then the t_relay() of the INVITE after $T_fr_inv_timeout seconds results in fail with $retcode -6, I checked the doc it says "generic send failed". I am not too sure what does that means. If both B and C are in v4 only env, then it works without any issue. A(v4) => opensips(v4/v6) => B(v6) - working A(v4) => opensips(v4/v6) => B(v6) => C(v4) - not working A(v4) => opensips(v4/v6) => B(v4) => C(v4) - working Could you please shed some light on it? -- Regards, William Jin
