asterisk users - Jun 2011 - Cisco IP Phones and Skinny in asterisk

Hi All;

Can anyone advise if using Cisco IP Phones in skinny protocol is fine or not? Or
it is better to use it in SIP protocol?

SCCP works better than SIP in my opinion as there are more features.
Check out http://chan-sccp-b.sourceforge.net/

The Asterisk version is 1.8.3.2

The Cisco IP Phone is 7942G and it is running now skinny.

The used TFTP is tftp-server which is installed in fedora.

I placed the following two files (but look like it was not taken from the TFTP,
as nothing appeared in the messages), but I am able to to ping from the asterisk
box to the vlan that the Phone is connected, so no problem in the reachability:


SEPB8BEBF22AB62.cnf.xml
xmlDefault.CNF.XML

Are the files name correct? Or the Cisco IP Phone 7942G are not working fine
with Asterisk or the tftp-server?

tcpdump will show you if the tftp configuration is working.

OK, I start beleive that the problem in the TFTP and the files that I placed
there.

Now, I am using the Phone as skinny, and the files that are placed in the
directory /var/lib/tftpboot/ as following:

CTLSEPB8BEBF22AB62.tlv
SEPB8BEBF22AB62.cnf.xml
XMLDefault.cnf.xml

Well, actually the CTLSEPB8BEBF22AB62.tlv is totally empty, so should I place
any thing in it? Anyone has a format for the file CTLSEPB8BEBF22AB62.tlv?

Also, what do I miss other files that the Phone needs it?

 Cisco has changed the file name format a few times, so
you may want to copy xmlDefault.CNF.XML to XMLDefault.cnf.xml

The more important steps is how have you configured the phone
to locate the TFTP server?  Are you using option 150 in DHCP, or
manually setting the TFTP server address on the phone.

Technically you do not need a TFTP server, since the Skinny phones
will try to use the TFTP server address for registration, so you
can just set that address to point to your asterisk server. A TFTP
server is needed if you want custom ringtones or to manage software
updates.

For small setups or my home, I skipped setting up the TFTP server
until I wanted to update the phone firmware.

OK, I have two things now:

1) When I do reload from the asterisk CLI, then all the skinny phones are reset.
This is very bad thing, how to avoid this from happening in each reload? Even if
the reload will be done to take sip configuration !!


2) The line tone that is heared (the normal toooooooooo tone which is heared
when picking up the handset to place a call), now: while dialing the digits, I
stay hear the tooooooooooo !!! It start ringing at the destination and I am
still hearing the toooooooooooooooooo, the destination answer the call and I am
still hearing the toooooooo.

How to resolve this?

Please note that currently I am not giving the Phone any files from the TFTP, I
just give the Phone the TFTP IP address (which takes it from the DHCP option)
and it come to asterisk and register.

I am able to call the extension of this Phone and it rings, but when pickup the
handset to answer the call, I just hear toooooooooooo even the caller with me in
the line and he is saying Hellooo but at Cisco Skinny Phone, I do not hear his
voice, I just hear the tooooooooo.

Appreciate the kindly help.

Have you thought about perhaps just flashing the phones to use the SIP
firmware?

Dear Stefan;

First of all, I tried skinny and I faced two major problems (so if I am going to
face same problems in sccp then no need to use sccp, so please advise).

The two problems that I faced them are:

1) When I do reload then the skinny channel is reloaded and that will cause a
restart for the Cisco IP Phones (that are registered to skinny channel). Is the
same thing happening with u when u r using sccp channel?

2) When I called the Phone, it is ringing, when we pickup the handset to answer
the call, we hear toooooooooooooooooooo and we do not hear what source is
talking and source does not hear us even .. but if we select music on hold, then
caller will hear the music. Also, when we tried to use the Ciscp IP Phone to
place a call, while we are dialing, the toooooooooooooo tone is always existed
and it is ringing at destination but no voice (always toooooooooooooooooooo).

So, with sccp no problem?

If I need to use SIP, from where to get the suitable firmware for these Cisco IP
Phones 7942G?

Where do u download the SIP firmware usually for your Cisco IP Phones?

Your kindly help is highly appreciated.
Regards
Bilal

Dear Dan;

I have to do something in the compilation to have chan_sccp? Because, I do not
have this channel and I have only chan_skinny.

Even in the /usr/lib/asterisk/module/, I did not find chan_sccp.

Maybe that is the reason why I do not have the sccp.conf file?

So, using the sccp channel, will also face the same problem that the phones will
restarted if I did reload?

Bilal

You do not need sccp.conf if you are not using chan_sccp.
It has different features(bugs) than chan_skinny, but yes
it would also reset the phones (if it supports reload, and 
I have no idea if it does).

Also if the phone is in a call it will not reset until after
the user hangs up.  Reloading the channel triggers a soft reset
that causes the phone to request its configuration, which may have
changed.

Dear Warren;

It look like u have a good experience in 791x series and in selecting SIP
formware, so I am sure you might be able to help in the following:

As u know, there are SIP firmware for Cisco phones to be used with Call Manager
and other firmware to be used with Generic SIP Server (other than Cisco Unified
Call Manager). Actually the firmware that start by P0S is that used for Generic
SIP Server and that start by cmterm is used for Cisco Unified Call Manager.

Can I understand from ur blog, that u can use the files that its name start by
cmterm to make the Cisco IP Phone to be SIP image that can be used by Asterisk?

In my case, as the Phones are 7942G, then there are two files are available,
really I do not know the difference between them (if u can advise):

cmterm-7942_7962-sip.9-2-1.cop.sgn (which is written that it is SIP IP Phone
load) and cmterm-7942_7962-sip.9-2-1.zip which is written that it is SIP IP
Phone firmware files only. So what is the difference between them "the load
and the firmware"?

Now, when I need to do the upgrade for the Phone, then I have to determine in
the xml files the needed firmware?

Appreciate your kindly help.

Regards
Bilal
