Hi tony,

Why would you not recommend enabling a firewall on sipX, is this not
supported configuration by sipX?

I don't know how well that iptables scenario will work with remote
workers.
Do your remote workers come in on the same Cisco router as your SIP
trunk(s)?

        You could probably use iptables (should already be installed on
your sipX

install the RPM) to set up iptables (networking->linux firewall->allow
all
traffic) and then try adding/replacing the following lines to the top of
your /etc/sysconfig/iptables file:

REDIRECT --to-ports 5080
        COMMIT

________________________________

        where ip.addr.of.cisco is the IP address of your cisco device

        and restart iptables by running service iptables restart
        to make sure this survives a restart, run chkconfig iptables on

                That is outside of my skill set, but I was advised
against attempting
                something similar when I ran into the issue. We
translate 5060 to 5080 on
                traffic from the Verizon SBC. That has worked fine for
us. They were not
                able to alter the port for a particular customer either.

                Thanks for your input, and that is my option two - the
Cisco router
                which terminates the SIP trunk has feature called ALG
(application level
                gateway) running to handle NAT from LAN to WAN. I don't
want to break
                that, I may test this and see what happens.

                Do you know if my original suggestion will work? If not
why?

                If you have control of the LAN, ca you add a router that
can do a port
                translation? I had a similar issue.

                Hey Tony,

                Thanks for replying so fast, I can not get a new ITSP
unfortunately so I
                have to find a solution!

                I should have mentioned that the SIP trunk I have is a
dedicated WAN
                link into the Tier 1 Operator network the network side
is connect to a
                Acme Packet SBC (its like a standard product they have
so they are not
                able to make an configure change without months of
planning and risk
                analysis. And sending port is definitely a no no anyway!

                I have full control over the LAN but the problem is I
can not change the
                incoming port from the trunk as mentioned, I would like
to understand
                why my proposed solution will not work, can you please
help with that?

                On paper it seems very straight forward, so from your
input I will
                adjust my design systematically until I come to the
perfect solution
                which fits my requirements.

                Your best option is to get a new itsp. Then use a real
firewall, your
                hands
                are REALLY tied.

                You would have to run 2 instances of sipxbridge with 2
different public
                ip
                addresses (one for remote users, the other for
trunking). Since that
                means
                firewall changes you can't make, you are STUCK.

                Fire the ITSP, then the incapable firewall manager and
get REAL
                replacements.

                Plainly said, you can't get there from here. Good luck.

how?

                Hello All,

                Purpose:

                Need to enable SipXecs bridge to solve lack of REFER
support on SIP
                trunk.

                Problem:

                1. SIP trunk provider has very strict rules about
changing any
                configuration on any component that they manage. The SIP
trunk comes
                with a Cisco 2801 router which is managed by the
Operator and the port
                they signal on is 5060, this is a problem because all
requests from the
                trunk are bypassing SipXecs bridge which listens on port
5080 therefore
                REFER can not be influenced.

                2. SIP trunk Operator will not change port on trunk
                3. SIP trunk Operator will not change config on Router,
so I can not do
                any NAT as recommended here:
        
http://sipx-wiki.calivia.com/index.php/SIP_Trunking_with_sipXecs:_Overvi
                ew_and_Configuration#2._Configure_SipXbridge

                4. Do not want to change SipXecs internal port to some
else, sounds
                dangerous and messy
                5. Do not want to try another sip trunk provider

                My solution to the problem: (please provide feedback and
answer my
                question below)

                1. Configure two physical sipX components
                (a) sipXbridge(only) IP Add: 192.168.0.1 Port 5060
                (b) sipXpbx(proxy) IP add: 192.168.0.99 port 5060

                2. Configure (b) sipXpbx with provider gateway address
123.123.123.234
                3. Configure (b) sipXpbx with route under gateway config
to
                SipXbridge(a)IP add: 192.168.0.1
                4. Configure SipXbridge (a) to receive/send signalling
from provider
                gateway and pass to/from (b) sipXpbx

                Questions:

                1. Will this solve my problems?
                2. is my suggestion possible?
                3. if so, how do I configure sipXbridge?
                4. if so, are there any draw backs that you are aware of
by implementing
                this design?

                Your help would be much appreciated.

                No you should not configure it this way. You should
configure it as
                follows:

                1. Allow sipx proxy server to continue to listen on port
5060.
                2. Allow sipxbridge to continue to listen on port 5080 (
both of these
                are defaults ).

                3. Set the public port in the sipxbridge configuration
page to port
                5060. See
        
http://sipx-wiki.calivia.com/index.php/SIP_Trunking_with_sipXecs:_Overvi
                ew_and_Configuration#2._Configure_SipXbridge

                4. Map your NAT to send WAN packets arriving at 5060 to
port 5080 on
                the host where sipxbridge  is configured and vice versa.
