Hi list,

I have bought some Cisco 7941G-GE IP phones and want to use them with
asterisk. Before bying I tested the whole setup with three different
models of the old 79X0 series (a 7912, 7940 and a 7960). Flashing the
formerly provided SCCP-Image to SIP was no problem, but now it complains
about a nonexistent CTLSEP<mac>.tlv file. Most of the howtos say
something about an empty file but that does not suit to me. Does anyone
of you have experience in getting these phones to work or can point me
to any information bringing me back in the game?
Thanks in advance,

Christophorus Laube

I've always found it best to run with no CTLSEP<MAC>.tlv file in the
tftp server directory; it will ignore that and move on.

With the 7961's you'll be best in the 8-3-3SR2 leading edge, the DND
button is where it should be, and transfers work the way they should
again.

The XML configuration file is different, I'll post one onto the Wiki
that actually works and takes updates.

Can you post a pinout of the cable that you're using for serial? I have
a 6 Wire cable and a RG12 (6 Wire) to DB-9, but no working pinouts...

Ideally from End to End pinout would be great.

Thanks,

Chad

Here is the info on the Cisco console cable I use. There are a couple ways
to make the connection depending on what you have available. I used a piece
of 6 wire flat satin (like the 4 wire telephone station cord only with 6
wires) and put an RJ-12 on one end then put an RJ-24 on the other with the
cable aligned to fill the 6 middle connections. Make sure to put the same
side up on both ends (like a telephone wire) so that it is a straight
through cable. Then I used a Cisco RJ-24 to DB9 terminal adapter that comes
with a router or switch to connect to the PC. If you don't have that adapter
and need to crimp or solder your DB9 connector (blech...) the pinout is
below.

I don't remember the correct way the pins are labeled on the RJ connector so
you need to be looking at it with the clip away from you and the cable
opening on the left then start with the top pin as pin 1.

DB9 RJ12
1 NC
2 2
3 5
4 6
5 3&4
6 1
7 NC
8 NC
9 NC

Hope I was detailed enough....

Your nomenclature on the modular plugs are incorrect.
RJxx references specific JACK wiring schemes originally defined in FCC
part 68, but removed in year 2000
There are:
4position 4 contact plugs - used for handsets and Sangoma A200
6 position plugs, with either 2,4 or 6 contacts - commonly and
erroneously called RJ11
8 Position plugs with 8 contacts used for many applications, including
Ethernet
10 position plugs - seldom if ever seen.

You are correct, I made some corrections.

of 6 wire flat satin (like the 4 wire telephone station cord only with 6

connector on the other with the cable aligned to fill the 6 middle
connections. Make sure to put the same side up on both ends (like a
telephone wire) so that it is a straight through cable. Then I used a Cisco
RJ-45 to DB9 terminal adapter that comes with a router or switch to connect
to the PC. If you don't have that adapter and need to crimp or solder your
DB9 connector (blech...) the pinout is below.

DB9 6 pin Modular connector.
