I have an IPO 500 v2, VCM32 card with PRI daughter card. I have 4 8 channel PRI E1R2 licenses. The system is in Mexico (thus the E1R2). We only use the E1 for incoming calls. All outbound calls use SIP trunks. We have no problems with outgoing calls on the SIP trunks, and don't seem to have any issues with calls coming in (at least I haven't heard any complaints), however, in the System Status app, we get messages that say "no trunk license available for call" for the PRI line. I've gotten about 40 of them in the last 3 days since we plugged it in. I've searched online and I cannot find any reference to this error. Any ideas? Do I need another license for the PRI card besides the channel licenses?
