CSS/Parition question. Inbound calling. MGCP. If I have a site where the CSS assigned to the gateway is called CSS_PSTN. A phone assigned to the "internal partition" CSS_COS5 (international calling), however the internal partition is not assigned to the CSS_PSTN. Incoming calls work fine, Can someone tell me how this is possible based on the current setup? I would think the gateway would need to have all partitions that are assigned to end points within its CSS. Thoughts?
