Hey, thanks for the reply..

Yes, I have one line coming out of the ATA and going into a splitter and from that splitter one end goes into the PC running mgetty and the other end goes into a dumb phone that has caller ID. And when I make the call I can see the dumb phone ringing with the correct caller ID number as well as I can see mgetty Ringing while watching the log file.

So both my laptop and the PC running Mgetty both have DID numbers assigned to them.

Also, if I call the mgetty PC from my cell phone, I can see my cell number on the dumb phone's Caller ID but mgetty shows it as "none"...

Thanks Again,
Matt

Ahh crap....

So other then the 15 Zoom USB modems I already purchased for a project, I have 2 or 3 TrendNET USB Modems...

So I shutdown mgetty, unplugged the Zoom modem and connected the TrendNET modem, then restarted mgetty. I did NOT change any of the init-string
stuff or any configuration data and this time when I called from my cell phone, the correct caller-id number showed instantly in the mgetty log file... I really hope
this is not an issue with all the Zoom modems or else I'm SOL.

I was wondering if it was the Caller-ID's AT Command I'm sending to the modem as part of mgetty's config, which is AT+VCID=1, the 1 simply means to show
formatted CID information. So I changed it to AT+VCID=2, which means to use unformatted CID information, but that didn't seem to change anything
in terms of receiving any CID information from an outside caller...

Any advice or suggestions??

Thanks Again,
Matt

******** UPDATE ********

So I just tried something else...

I connected the same USB Modem to my Windows XP VM and started Putty Serial connection for the USB Modem. Then the ONLY AT command that I sent to the
Modem was the Caller-ID Command, which is AT+VCID=1. Then I called the USB Modem connected to the Windows XP machine from an internal extension and got the
4-digit extension as expected in the Caller-ID information. So I hung up that call and called the full DID number from my cell phone this time and Putty then
displayed the FULL, correct Caller-ID information...

So it looks like it might be an issue with mgetty. Any ideas what it could possibly be, I'm at a bit of a loss here..?

Thanks again and sorry for the consecutive posts.

Thanks,
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.
