Hi Hope someone can help me.

I've got 6 nodes connected using SPNET.
Node 1 is a OS 7400 on V4.70 software.
Node 2 and 3 is 7200's on ver 4.6. node 4 is an OS 100 with mgi card.
node 5 is a 2-cab 7030 ver 4.53c and node 6 is a OS 7070 on ver 4.70 software.

The current setup of PABX to PABX communication is via IPSEC VPN on the
internal LAN Address and Firewall/Port Forwarders are not applicable on
the LAN to LAN VPN. All ports are allowed in the VPN channel.

I can phone between node 1 to 5 without any problems.Node 4 and 5 can phone node 6.
When i phone to node 6 from node 1,2 and 3 i get "no user response.
When node 6 phones node 1,2 or 3 and you return the call to node 6 within 20 seconds it works.

Everyone tells me that the billion router keeps the route in memory for 20 seconds
and that is why i can return the call.
When i replace the OS 7400 with a OS 7030(for testing)i can call node 6 without a problem.

Please help.

You must append the # to make an inmediate call between systems.

Does the problem is random or always happens?

Hi Francisco

This problem always happens. If I dial the SPnet group then the system id then the extension number and then the # the call also fails.

Make sure you can ping the systems
Had problem like yours was because ping was not enabled but you have vpn don't believe you need that enabled

Hi

I can ping the system no problem. I can phone from node 6 to node 1. When I phone from node 1 to node 6 I get no user response. When I phone from node 6 to node 1 end the call and phone within 20 seconds from node 1 to 6 the call goes through.

Don't know what to do anymore

Thanks

make sure mmc861 and 825 is set to mcp signalling. Was stuck in similar situation and stumbled on this by accident

No user response means the systems can't talk to each other (in this case the response from node 6 isn't getting to node 1).I've seen this before with public registered systems (firewall not keeping the ports open), a vpn usually fixes it.

Check your route tables when the call fails
