Mgetty Not Answering when Calling from Outside

Hello All,

mgetty Version: 1.1.36
OS: OpenSuSE 13.1 (armv7l)
Modem: Zoom 56K USB Modem Model 3095

So I've been playing with mgetty for weeks now testing dialing into the USB modem from another PC using the same modem and connecting
using minicom (*minicom ---dials to---> mgetty). I had to recompile mgetty from source so I could enable support for the dialin.config file
which tells mgetty what calls to answer using the Caller-ID.

Internal Testing:
The testing I was doing was internal using a Cisco ATA 186 with 2 phone lines (*one to my laptop and one to the PC running mgetty). Since these
tests were internal the Caller-ID was showing up as 4 digit extensions. Which seemed to work fine. If I put the extension my laptop was using
inside dialin.config it would ONLY issue a CONNECT to my laptop' extension and I could remotely login to that PC over dialup.

External Testing:
Now for External testing, i.e. where the call actually leaves the building in order to reach the PC running mgetty...
What I did was I added the full external Phone Number Mask to the dialin.config file for what my laptop will display after it leaves my building. I restarted
mgetty to take the new config and now when I dial to mgetty it is no longer accepting my call and mgetty is saying the Caller-ID is "none".

I know that the Caller-ID is displaying correctly because before the phone line goes into the USB modem it is attached to a splitter and the other
end is connected to a dumb phone with Caller-ID on it. So when I dial the mgetty PC I can see mgetty is RINGING in the log and that the dumb phone
is displaying the Caller-ID information... So I'm really confused as to why the Caller-ID is showing as 'none' when there is a phone number present for
my outbound call.

Thinking that maybe the issue was with the External Phone number mask that gets assigned when it leaves my building, I added my cell phone
number to dialin.config and called the mgetty PC from my cell, and that also displayed in the mgetty log as 'none'...

Anybody have any idea what could be going on here... I'm really confused why it works for 4-digit extension, but not a full 10-digit phone number?

ANY thoughts or suggestions AT ALL would be greatly appreciated!

Thanks in Advance,
Matt

umodem

UMODEM(4)						   BSD Kernel Interfaces Manual 						 UMODEM(4)

NAME

     umodem -- USB modem support

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device umodem
	   device ucom

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   umodem_load="YES"

DESCRIPTION

     The umodem driver provides support for USB modems in the Communication Device Class using the Abstract Control Model.  These modems are basi-
     cally standard serial line modems, but they are accessed via USB instead.	They support a regular AT command set.	The commands can either be
     multiplexed with the data stream or handled through separate pipes.  In the latter case the AT commands have to be given on a device separate
     from the data device.

     The device is accessed through the ucom(4) driver which makes it behave like a tty(4).

HARDWARE

     Devices supported by the umodem driver include:

     o	 3Com 5605
     o	 Curitel PC5740 Wireless Modem
     o	 Kyocera AH-K3001V Mobile Phone(WILLCOM)
     o	 Kyocera WX320K Mobile Phone(WILLCOM)
     o	 Metricom Ricochet GS USB wireless modem
     o	 Sierra MC5720 Wireless Modem
     o	 Yamaha Broadband Wireless Router RTW65b
     o	 ELSA MicroLink 56k USB modem
     o	 Sony Ericsson W810i phone

SEE ALSO

     tty(4), ucom(4), usb(4)

HISTORY

     The umodem driver appeared in NetBSD 1.5.	This manual page was adopted from NetBSD by Tom Rhodes <trhodes@FreeBSD.org> in April 2002.

BUGS

     Only modems with multiplexed commands and data are supported at the moment.
