Limit call duration inbound analog trunks not outbound

[mitelrocks]

Hello everyone.  Been fighting this problem for sometime now. Have a 3300 with 3 analog trunks. Client wants to setup call duration limit on all external calls over the analog trunks (for 10 minutes), but not have a call duration on the incoming calls over those analog trunks.  I setup a COS on the phones (COS setting 'enable call duration limit on external calls').   I am able to restrict the call duration for all of the external calls just fine...calls are gracefully cut after 10 minutes, but all of the incoming calls over the analog trunks are also cut after 10 minutes.    I removed that COS setting for the phones, then applied a different COS for the analog trunks ('enable call duration on external calls') and the same thing happens...incoming calls over 10 minutes are cut.  Running MCD 4.1.   Is there a way to seperate this condition?  Any ideas?

There isn't a way to separate that except to separate them into in and out trunk groups.   
What you would be doing then is limiting outbound calls only to trunks that will disconnect.

Thanks Ralph....makes sense.  We'll see what the client wants to do then.

Are you using a different COS for the trunks and the phones?

Yes, I set a different COS on the phones verses the analog trunks.
