What we got is...when a call comes in on node a and gets transfered to node b using spnet, the call disconnects at exactly 20 mins. I have programmed the CO-CO timer to disconnect at 250min. If the call comes in or out on node B were the extension is programmed to, there is no problem. Only when going across nodes. Am i missing something. Is there a spnet timer?

The systems are node a is 7100 and b is 7400 sw is 4.30i in both
