I'm trying to configure the T1 card on my uc520 to use the channel signalin (E&M)
because the isdn signaling options are not enable in the avaya pbx that Im trying to connect too.
Under the Channels (DS0groups) I have the option to separate groups for incoming and outgoing calls
is it recommended to enalbe this option?
I have not enable this option and have configured the avaya PBX on this site to use E&M signaling.
On a Remote site I have configured another uc520 connected to another avaya PBX using ISDN-PRI.
everything on this site seems to be working ok.
I'm able to make calls from this Avaya pbx routed them through the uc520 over the wan to the remote uc520 and into the remote pbx with no
problems, but I'm unable to do the same thing from the remote side.
