Hello,

first just a question to clarify regarding the ip addresses: you edited the logs to show 2.2.2.2 and 8.8.8.8 instead of real addresses, right? Just to be sure as 8.8.8.8 is google DNS server and I have seen in the past some local caching dns systems returning the dns server ip if the domain had now dns entry (e.g., wrong domain).

Cheers,
Daniel

Hi All,

I'm unable to register an extension to the Upstream Provider by using uac module.
Getting the following error:

Kamailio is listening on 2 interfaces: 
[root@kamailio user]# /usr/local/sbin/kamcmd core.sockets_list
{
        socket: {
                proto: udp
                address: 10.1.1.11
                ipaddress: 10.1.1.11
                port: 5060
                mcast: no
                mhomed: no
        }

socket: {
                proto: udp
                address: 2.2.2.2
                ipaddress: 2.2.2.2
                port: 5060
                mcast: no
                mhomed: no
        }

mhomed is enabled in the configuration file: mhomed=1

I'm not using ' force_send_socket' anywhere in the configuration file. 
This is the uac module configuration:
modparam("uac", "reg_keep_callid", 1)
modparam("uac", "reg_contact_addr", "2.2.2.2")
modparam("uac", "reg_db_url","cluster://kamailio")

If i'm disabling mhomed from configuration file - i don't receive any errors - but then kamailio is trying to send the message to the external server (8.8.8.8) through internal interface (10.1.1.1).
Thank You.
