attendant DN versus DN

Hi All,

I've setup VG224 with 24 FXS ports. each port has attendant DN and also DN which can be assigned to that port. what's the difference between these two? I know in FXO port, attandant DN is similar to connection plar.

thanks

Alex

Re: attendant DN versus DN

Hi

When you add the ports you get a choice of loop start/ground start or POTS - POTS is your friend; did you select one of the others?

Re: attendant DN versus DN

Hi Alex,

For the VG224 the Attendant DN field can be left blank

It appears to be some sort of legacy/remnant left over from the VG200

days in reference to FXO Ports like you nicely noted. Here is a reference

that may help;

Re: attendant DN versus DN

Re: attendant DN versus DN

Does seem misleading, been a while since I've worked with a VG224.

I don't have one to test but from what I read and reviewed in a CUCM 8.x this happens when you have selected a MGCP FXS.

For FXS you need to choose:

POTS

Ground Start

Loop Start

The documentation doesn't explain this but apparently you need to use POTS for phones, the other 2 options are meant for trunk lines.

This to address a bug:

CSCse23808
CCMAdmin should support MGCP-controlled analog FXS GroundStart endpoints

But generated another bug to remove that attendant DN and avoid confussion

CSCtf22348
MGCP FXS GroundStart and LoopStart need Prefix DN; remove Attendant DN

So, apparently attendant DN under GS/LS is useless. What you need to use is prefix DN for PLAR from what I read.
