Alcatel Unleashed

Hi everybody,
We have a network of a4400 (almost 20 nodes), all they are IP trunk, but other node is linking with a E1 (pra2), they all have release 9.1, the other node with pra2 was in version 7.1 with cpu 6, and it could call to every node with no problem, but i changed that node to cpu 7.2 release 9.1 and i can call to some node without problem but to others all extensions give busy, if I make a recall (after a few seconds) it gives me the recall and the call it´s ok, but a direct call I can´t do it. What can I check. all is a A4400.

Thanks for your answer.

Only upgrade? Nothing else? Maybe not enough compressors. Check with compvisu and also check incvisu for details

For internode calls (when in network exist some nodes with old releases) - system/ other system/ network parameters - item "Network Enable UTF8" - try to disable.

Thanks, I am going to check those items, and I´ll tell you.

IT SOLVED, the problem was that in the traductor the vpn hop was -1 I changed a value more than I put in Internodelinks, vpn hops in this case 2 and it solved the problem.
Thanks to everyone.
