Hey Russel, thank you for your response.

 

Nope, there're no NATs in my setup.

 

I also should mention, that when I test my setup on FS machine with sipp:

 

sipp -d 1 -r 1 -m 1 -i fs.ip.addr 1.1.1.1:5060

 

------------------------------ Scenario Screen -------- [1-9]: Change Screen --
  Call-rate(length)   Port   Total-time  Total-calls  Remote-host
   1.0(1 ms)/1.000s   5061       1.08 s            1  1.1.1.1:5060(UDP)

 

the target sip server gets incoming call as it should do.

 

Thanks / Mike

Is there NAT anywhere between the sip endpoints?

Hi All,

 

I want to register my FS machine (FreeSWITCH Version 1.6.0 - git 6762f14 2015-09-03 20:36:52Z 64bit - CentOS 6.7, selinux is disabled for debugging) as endpoint at another target SIP server (1.1.1.1). This is my gateways section:

 

    <gateway name="1111">
        <param name="register" value="true"/>
        <param name="register-transport" value="udp"/>
        <param name="username" value="1111"/>
        <param name="realm" value="1.1.1.1"/>
        <param name="password" value='my_strong_pass"/>
        <param name="proxy" value="1.1.1.1"/>
        <param name="expire-seconds" value="90"/>
    </gateway>

 

The problem is - a target server at 1.1.1.1 receives absolutely no packets from my FS machine and I'm getting constant registration timeouts:

 

2015-09-21 15:01:46.764466 [ERR] sofia_reg.c:2101 487020870 Registration Failed with status Request Timeout [408]. failure #1
2015-09-21 15:01:46.864501 [WARNING] sofia_reg.c:469 487020870 Failed Registration [408], setting retry to 30 seconds.

 

Meanwhile, when I do UDP scan of port 5060 on 1.1.1.1 from FS machine, I see that port is opened:

 

[root@srv]# nmap -sU -Pn -p U:5060 1.1.1.1

Starting Nmap 5.51 ( http://nmap.org ) at 2015-09-21 15:28 EEST
Nmap scan report for 1.1.1.1
Host is up.
PORT     STATE         SERVICE
5060/udp open|filtered sip

Nmap done: 1 IP address (1 host up) scanned in 2.28 seconds
[root@srv]#

 

When I filter out port 5060 on target machine 1.1.1.1 I see appropriate lines in the log showing filtered requests:

 

Sep 21 10:39:57 sip kernel: DROP IN=eth0 OUT= MAC=00:16:3c SRC=2.2.2.2 DST=1.1.1.1 LEN=28 TOS=0x00 PREC=0x00 TTL=52 ID=10616 PROTO=UDP SPT=47229 DPT=5060 LEN=8
Sep 21 10:39:58 sip kernel: DROP IN=eth0 OUT= MAC=00:16:3c: SRC=2.2.2.2 DST=1.1.1.1 LEN=28 TOS=0x00 PREC=0x00 TTL=47 ID=23653 PROTO=UDP SPT=47230 DPT=5060 LEN=8

 

Firewalls on both machines are off for debugging:

 

[root@srv]# iptables -L -n
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
[root@srv]#

 

I've spent many hours while investigating that quest but still have no ideas on what's happening. I'll highly appreciate if someone can point on where else I can look to resolve my issue.

 

Thanks in advance

 

Mike
