I am having an issue on my UC500 where I have 2 blast groups set up for multiple extension ring appearance. The first blast group works as advertised where I have 2 POTS lines on FXO ports set in a hunt group by Verizon. The second blast group rings different extensions then the first, has 3 POTS lines to FXO ports set in a hunt group by Verzion and does not work as advertised. The issue I am having is that the call will come in on the main number voice-port 0/1/0, ring twice with the proper caller-id (but keep ringing on the caller end), skip a few rings, then ring the blast group again as an anonymous caller. With this said the lines have been tested outside of the UC500 and they work correctly however when plugged into the UC500 the afore mentioned scenario occurs.
I am also having an related/unrelated issue where the FXO ports will show an off-hook led but the show status command sees them as on-hook. The inbound caller will get a fast busy and it seems as if the blast group is locked and thus far has only been cured by a reboot.
Thanks for your help.
