Dropped Calls after 8 minutes

[pkaloger]

Hello All,

I have 2 Prologix Rel 11 networked together via IP trunking using ISDN signaling. All calls come into node 1 and get transferred accordingly, Some call come in via a PRI DID trunk group and other via POTS lines, When a call comes in from node 1 and gets transferred into node 2 the call drops after 8 minutes, it does not make a difference if its through the T1 circuit or the POTS lines. But if a call comes in via a DID number and passes through into node 2 it does not drop. Intercom calls from one node to the other will also not drop. Any Ideas?

Hi,
Did you already check CORs(second pages) of both trunk-groups to look at disconnect timer field?


Will think more...

If you are using a vector for routing incoming calls,
check Vector disconnect timer in system feature ...
