Have any of you guys connected a SIP box to an analogue trunk via FXO? I've got a Linksys SPA3000 and I just cannot get it working. I think it must be the port impedance (600), tip/ring voltage adjust (3.5V) or the line in use voltage (30) settings. The FXS port works fine in and out. Any help greatly appreciated. Andy

Sorry Andy
Your UK stuff is so different than what we use here in the States. What are you using out of the Telrad? SLD SHD ONS or TVsE

Just a plain old analogue CO line on an MPD1. Andy

Did you try connected to a COL or COG set for loop start? And what software level if after Rel7 you have some impedance settings Short/Long/VeryLong?

I've tried all the basics like this, the CO stays in Maint fail mode (incorrect voltage?). I'm running sb7.33 and have tried the maint testing option. The FXO is loop start only. The ironic thing is it works fine on basic switches like Pana KXT, it seems the Telrad is more discerning and less forgiving (as always!). Andy

Check the open loop timer. We use to adj this when the customer wanted to page from a trunk port.
