Intercom and making outside calls not working

[Beeker]

Currently I have a Linksys PAP2 with a POT's standard phone connected to it with a VOIP account and it is connected to Linuxmce and I can only make outside calls from the phone connected to the PAP2, the SIP account is registered in webadmin but I cant make calls from MD's or even do intercom calls between MD's. I have checked the trunks and dialing rules and all seem to be correct ........anybody have some ideas of things I should start checking as I want to install a SOLO usb MIC to be able to use it. I don't have a direct in dial number a of yet as owe use the standard POT's for incoming calls

Added to this if I try to make intercom or outside calls I get a msg on the orbiter Failed to make call: ERROR Couldn't make call from Device 68 to xxxxxxxxxxxl
