Remote 9600 and SIP Trunk problem

[vladcbv]

Hi y'all!

I am testing the Powered By solution - in my lab environment.
So I have Server Edition 10.1 with demo licenses. (there is no problem with my liceses and you will see why in a few). ipo has 192.168.42.17 with GW: 192.168.42.254

I have configured 9630D over internet to connect to IPO (port forwarding to IPO) and it works. only if I create IP Route 0.0.0.0 0.0.0.0 192.168.42.254.

Now I want to add the sip line. I configure all line and voip LAN2 settings but for this line to work I need to configure another 0.0.0.0 0.0.0.0 2.0.134.xxx (gateway ISP) . since i cannot have 2 default gateways i have to choose between using a sip line and not using remote phone, or using the remote phone and not using the sip line.

So, if the phone is registered then monitor logs show that Sip tries to register via local ip :

10:23:19 2481739mS SIP Reg/Opt Tx: 1
REGISTER sip:as1.romtelecom.net SIP/2.0
Via: SIP/2.0/UDP 192.168.42.17:5060;rport;branch=z9hG4bK216a5db30b6333660d6faa6067e118ac

User-Agent: IP Office 10.1.0.0.0 build 237

Content-Length: 0

as soon as i change the default gateway to make sip work, remote phone loses connection.

I am stuck here, it is a problem with the ip route but I can't figure out how to configure this..

Any clues?

Thank you,
Vlad C.

Then add a static route just for the SIP, ie

2.0.123.0
255.255.255.0
LAN2
2.0.123.xxx

Hi,

I tried it, i get the same thing.
11:01:19 4761584mS SIP Reg/Opt Tx: 1
REGISTER sip:as1.romtelecom.net SIP/2.0
Via: SIP/2.0/UDP 192.168.42.17:5060;rport;branch=z9hG4bK6d9be71f8e02533582e4621e40203539

FYI: Under LAN 2 Network Topology I have Open Internet.. and the Public ip set up ..

Why can't you connect the SIP line to LAN1 ?

I (almost) never use LAN2.

Good question.

Until now I only configured ipo500v2 with sip line - and for that i connected sip to LAN2 - this is how I learned to do it.

Now, this is my 1st time dealing with Server edition and I thought i can do it the same as with the cabinet. Plus the fact that Avaya told me to do so..

To configure SIP on LAN1, what needs to change?

 

[Pepp77]

The phone system will always use the local ip address in the headers. You get around this one of two ways.

1. Use network topology with the correct public ip address wntered to have the ipo rewrite them.
2. Use sip alg/ transformations on the firewall to have that rewrite the headers to use the public ip address.

Hi,
I have already set up correct public ip address for LAN1 and LAN2..
The SIP trunk comes from the provider box and it enters directly into the server.. I do not have access to the provider equipment to change settings..

When I reboot phone on the screen it sais HTTP: 1

http://92.87.95.53L80/96xxupgrade.txt

... then : HTTP: 1 7 then goes to Contacting call server and Discover 92.87.95.53 (which is public ip of LAN1)

 

[vladcbv]

Fixed it :

It was all about setting correct IP Routes.

So I have 0.0.0.0 0.0.0.0 2.0.134.xxx - LAN 2 - for the SIP and 92.87.95.0 255.255.255.0 192.168.42.254 - LAN1 -for remote phones

Thanks to everybody for the advices

Until you need a 2nd remote handset or it moves to a new IP address

Normally I would put all Voice devices on the same interface
so phones & sip would both be on either Lan1 or Lan2(doesn't mater too much which )
also for remote sip phones I would strongly recommend an SBC for security rather than port forwarding to the IPO.



Do things on the cheap & it will cost you dear

 

[vladcbv]

IPGuru thank you for the reply. I agree, we need an SBC. thing is this is my test lab so i have to work with what I have. Though I still don't understand how to configure all voice on one LAN.. I don't have time today to study this..

 

[janni78]

It's easier to configure all on one LAN than 2 =)

The only reason to use 2 LANs is if you need to show 2 different external IPs.
I've used it when I have 2 separate internet connections for SIP trunks from 2 providers.
