TCP alone errors were strange : on the proxy node i couldn't register and got the following errors : Feb 25 12:15:28 server1 [Proxy-CSCF][31641]: ERROR: tm [ut.h:303]: uri2dst2(): no corresponding socket for "NET.SYRIATEL" af 2 Feb 25 12:15:28 server1 [Proxy-CSCF][31641]: ERROR: tm [t_fwd.c:469]: prepare_new_uac(): can't fwd to af 2, proto 1 (no corresponding listening socket) Feb 25 12:15:28 server1 [Proxy-CSCF][31641]: ERROR: tm [t_fwd.c:1735]: t_forward_nonack(): failure to add branches Feb 25 12:15:28 server1 [Proxy-CSCF][31641]: ERROR: siptrace [siptrace.c:1930]: trace_send_hep2_duplicate(): can't forward to af 2, proto 1 no corresponding listening socket Feb 25 12:15:28 server1 [Proxy-CSCF][31641]: ERROR: sl [sl_funcs.c:362]: sl_reply_error(): stateless error reply used: I'm terribly sorry, server error occurred (7/SL) =====================================================================================
These errors appearing when using two TCP and UDP, i could be able to register and make calls but still get errors Feb 25 11:37:15 server1 [Proxy-CSCF][28999]: ERROR: ims_usrloc_pcscf [udomain.c:409]: update_pcontact(): Error updating record in DB Feb 25 11:37:15 server1 [Proxy-CSCF][28999]: ERROR: ims_registrar_pcscf [notify.c:218]: process_contact(): failed to update pcscf contact Feb 25 11:37:15 server1 [Proxy-CSCF][28999]: ERROR: tm [tm.c:1242]: w_t_reply(): cannot send a t_reply to a message for which no T-state has been established In addition i cleaned all UDP SRV related records from DNS zone and tried to forced all instances in the TCP mode configuration **Also, in the TCP mode all the ip addresses that the registrations comes from are not the real ip's of the users, and also this is very strange i got some random IP's On Fri, Feb 23, 2018 at 10:41 AM, Daniel-Constantin Mierla < [email protected]> wrote: > Hello, > > have you look at syslog messages?
