help fixing an IP issue?

[Z-man]

So I am trying to figure out a way to fix an IP issue. Somebody else initially programmed the system a long time ago and I took it over.

they set up the following route to use as their SIP trunks routing.

0.0.0.0
0.0.0.0
Gateway for SIP
Lan2

See attached file.

Typically I setup the local gateway using this setting:

0.0.0.0
0.0.0.0
Local Gateway(172.20.2.254)
LAN 1

this way, anything that wants to connect to the IP office on the local network can. But since they setup the SIP routing using this, I cannot have a duplicate route like this. Probably the best solution is too define the sip trunking correctly, but they have so many issues with it, I hate to mess with it at all.


so here is what I need. I need my local IP office at IP address 172.20.2.230 to be able to connect to the local gateway so it can communicate with an off site gateway at 172.20.6.254, which has some remote IP phones.



Is this making sense? In the listed routing there is a route that points to the local gateway of 172.20.2.254, so I would have thought it works already but does not.

If I create a route using the following:

0.0.0.0
0.0.0.0
172.20.2.254
LAN1

I can connect to the offsite gateway but it kills the SIP trunks.

There is already an existing route of:

172.20.2.0
255.255.255.0
Gateway of 172.20.2.254
LAN1

I would have thought that this would work but it is not allowing the IP Office to communicate with the off site phones.

ps-tried to attach file but not working..

thx

That route is not correct:

correct:

172.20.2.0
255.255.255.0
Gateway of 172.20.2.254
LAN1


The target network (first line should represent the remote network.


IP Office remote service
Fixed price SIP trunk configuration
CLI based call blocking
SCN fallback over PSTN

 

[Z-man]

so you are saying this should be the correct route?


172.20.2.0
255.255.255.0
Gateway of 172.20.2.254
LAN1

That route DOES currently existing in the IP Office programming. But does not seem to work. If I got into System Status and attempt to ping the remote gateway from the IP Office LAN1 it fails.

I need my local IP office at IP address 172.20.2.230 to be able to connect to the local gateway so it can communicate with an off site gateway at 172.20.6.254, which has some remote IP phones.

172.20.6.0
255.255.255.0
G/W 172.20.2.254
LAN1

This tells the IPO that anything in the 172.20.6.x subnet can be reached via LAN1 through the gateway at 172.20.2.254
