Your registration will go out over Port 5060, and it requests it be returned
on 5080.   If your request comes back on 5060, it will go to the proxy, and
not to the sipxbridge.  Ensure it returns back to you on 5080.

 

On the Wiki, get familiar with sipviewer, and the use of the merge-logs, and
siptrace commands.  You can use this to pull logs of the registration and
see exactly what is happening with your registration.  Posting those details
will help others help you.

Subject: Re: [sipx-users] Inbound calls unsuccessful, outbound fine using an
ITSP. please help!

 

I was under the impression i could use nat to NAT port 5080 externally to
port 5060 internally to the SBC?

I have just changed the ITSP to register on port 5080, and removed my
natting on my pfsense box, so it is natting those ports to eachother
internally and externally...

It wont register, so i will ask my ITSP.

 

Regards

Will

the itsp won;t work unless you can register to them on port 5080 and they
send you calls on port 5080.

 

your firewall is not configured properly either and is not using symmetric
nat. what firewall is it?

 

consider another firewall (perhaps pfsense)

Hi Tony, 

             Thanks for the help.

 

1.      Im registering a static IP to the ITSP (our external one)
2.      they are sending calls to 5060, and im natting them to 6080
internally
3.      Im not sure looks like from a tcpdump i am registering on UDP port
5060 to them, and 62941 locally.

>From then, i am contacting the ITSP on port 5060 and they are contacting me
on UDP 62941.

Im guessing this is because i have registered with them on that port, and
they are then responding to me via that port, with my firewall keeping the
state of that port.

 

I am using pfsense 1.2.3, which shouldn't be a problem?

 

Regards

Will

Are you registering or using a static IP to the ITSP? Are they sending the
calls to port 5080 or 5060? If you register does the provider allow you to
confirm ip and port they see you registering on?

 

It would appear (and you can confirm) that the call is coming in to port
5060 from the ITSP in the initial invite on inbound calls.

Is you NAT static port NAT (symmetric ports) or dynamic? What is the
firewall?

Hi All,

         I am new to SipXecs, but I have worked with a couple of voip pbx's
before. Ive got a few days to set up a PBX in our office, and so far i am
struggling to find a solution to the problem i am experiencing. So id really
appreciate it if someone would reach out and help me.

 

I have a sip trunk from aql.com, and have configured it, it seems to work
(mostly)

I can make outbound calls to mobiles, landlines etc fine, and audio and
sessions establish and terminate fine.

However, i cannot complete inbound calls, the internal phone will ring, and
upon answering the call will terminate, however, the external callers call
will connect and stay connected untill they hang up.

 

I have my firewall + NAT rules configured correctly (ports external
5080-5081 = 5060-5601 internally + 30000-31000)

i have configured a dialplan from the username of the VOIP provider to the
internal extension.

 

I have wireshark dumps, and a snapshot if anyone would have a look at these,
and possibly help diagnose my problems, i would greatly appreciate this.

 

Regards

Will
