I'm probably missing something obvious here...
I'm using CUCM v7.0.1 in VMware attached to a 3725 as my MGCP gateway.
Outbound calls are working fine with partitions and CSS assigned.
Inbound calls are are different matter.
Without partitions and CSS assigned, indial calls proceed as expected from my PSTN lab router to any handset / DN. I'm using an E1 service (shouldn't matter), 4 significant digits and no number translations/transformations.
With a CSS assigned for inbound calls, and no partition assigned to the DN, the call proceeds as expected.
When I assign the PT_Internal partition to the DN, I get a fast busy signal. The CSS assigned for inbound calls contains the PT_Internal partition.
I'm open to suggestions at this stage, or to be shown my (bound to be obvious) error...
