We added a PSTN for voicemail via CCA (configure>voicemail>voicemail pstn #), but the UC does not answer the line. When we called the PSTN number's we discovered that two of the six lines are not answered by the UC's AA. Those two lines are on the VIC card and are the last two of six. The first four work fine.
Under Configure>telephony>trunks>pstn trunks, it shows Total ports 8 (4 built in, 4 VIC), so it sees the card.
Aside from a physical line cross connect mix-up issue, is there something else we need to do or configure to get those last two lines working.
Under our dial plan all incoming numbers currently go to a BLAST group.
I just tried a uc520 with CCA.
Its the incoming dial plan. ...select destination type operator and extension there (your AA extension)
If I understand, you want incoming call to hit your AA.
Once on the AA you can have a prompt action = transfer call to voice mail.
The FXO line are Telco lines so not really DIDs.
