We have 11 ATA-186s (running ata18x-v2-16-ms-030327b.zup) attached to Page-Pal overhead paging systems at each branch office. We are running CallManager 3.3(3)sr1. When an IP phone calls the paging system the ATA-186 does not release the line when the call is finished, a fast busy is being played on the overhead speakers, eventually something times out and the line is released. This only happens with the ATA-186s. Needless to say we need the line to be released as soon as the person calling in the page hangs up. In locations where we had FXO ports available we moved the Page-Pal to an FXO port and have had no problems, this is not an option for 8 of the sites however (no slots on the 2621XMs) Any Ideas?
