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

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

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

Hello,
have you look at syslog messages? Are there any errors? Between Kamailio
instances, tcp for sip should work. Check also configs to be sure UDP is
not enforced there.
Cheers,
Daniel

Hello list
For some reason i couldn't register on kamailio ims when i use only TCP
protocols between nodes, the error was solved when i enabled UDP between
I-CSCF and S-CSCF
is it mandatory for those two nodes to talk over UDP only ? or i'm missing
something ?
and in general for sip protocol which is better ? UDP or TCP ?
Regards,
