jbarber, 15:21 UTC, Thu 23 of Jun, 2005: Can't dial out from a 7920, I initially get invalid number, then every initial attempt says line is busy and I now have an X next to the phone. Any suggestions?

fpiergentili, 19:59 UTC, Wed 22 of Jun, 2005: Audiocodes MP-108 FXO, we can not listen the conversation of the PSTN side when we are talking at the same time, its feels like we dont have full duplex in the VoIP side. asterisk@iponline.com.ar

newerawisp, 19:52 UTC, Wed 22 of Jun, 2005: This Hongkong Broadband and VOIP is too expensive and a scam. VoIP should be replaced by a newely developed internet service that can be accessed by the use of a cell phone.I can be reached by mail at newerawisp@rediffmail.com

iraklis031, 07:59 UTC, Wed 22 of Jun, 2005: Not Getting RING Event from X100P. Any test / Debug Application ? iraklis.zografos@gmail.com

jbierlein, 02:23 UTC, Wed 22 of Jun, 2005: Anyone with experience configuring Cisco 2800-series with PC Based PBX's w/Dialogic Boards and VOS5 in a SIP, FGD environment. Email me and we can talk

klenkes, 13:25 UTC, Mon 20 of Jun, 2005: SIP is working for asterisk. But IAX is nice to have. Other way round: if you ask me as your customer if I'm willing to pay (more) for IAX access, I would take SIP instead.

AirStarCommunications, 05:07 UTC, Sun 19 of Jun, 2005: Question we are a wholesale carrier, does Asterisk users have a problem using sip for termination or would it be better to support IAX?

futtie, 09:40 UTC, Fri 17 of Jun, 2005: Hi all, Is there any way to prevent Asterisk from sending the first ring?

hfwang, 09:38 UTC, Fri 17 of Jun, 2005: hmm, that URL did not work :-) Search for 'voicemail password' and authentication through vm password will pop up

hfwang, 09:38 UTC, Fri 17 of Jun, 2005: Need some extra eyes on this script please: http://www.voip-info.org/tiki-index.php?page=Asterisk%20authenticate%20using%20voicemail%20passwords

SCCP-HOWTO2

history similar 4 comments

Here are some of my notes and sample conf files for SCCP.

Special thanks goes to Jan-Ahrent Czmok, who helped me with the setup of my Cisco 7920 on
the Asterisk server.

Main website http://chan-sccp.sourceforge.net
Main website (Old address?) http://www.lambda-solutions.de
Download latest code from http://sourceforge.net/projects/chan-sccp/

Install Instructions

1. Install a TFTP server some where on your network. You will need this to upload the firmware to the 7920.
2. Create OS7920.txt and enter the Asterisk server ip address in xmlDefault.CNF.XML, which comes in the tar file, and place these two files along with the firmware or bin file on the TFTP server.
3. If you are configuring a 7960 to work with Asterisk and SCCP you will also need to create SEP<MAC>.cnf.xml and place on the TFTP server, the 7960 (SCCP firmware 5.0.5) will continuously reboot until it finds this file.

xmlDefault.CNF.XML

<Default>
<callManagerGroup>
<members>
<member priority="0">

<ports>
<ethernetPhonePort>2000</ethernetPhonePort>
</ports>
<processNodeName>insert_the_asterisk_server_ip</processNodeName>
</callManager>
</member>
</members>
</callManagerGroup>

OS7920.TXT

echo -n "cmterm_7920.3.3-01-05" > OS7920.TXT
Create the file with the above command and enter the correct Firmware Binary file name (ie cmterm_7920.3.3-01-07)

3. Configure the 7920 to look to your TFTP server.
4. On the Asterisk server you will need to modify the hosts, modules.conf, sccp.conf and extensions.conf files.

/etc/hosts

(ip address) (server name)
Needed for RTP service (ie 192.168.0.41 MYPBX)

/etc/asterisk/modules.conf

...
noload => chan_skinny.so
; You need this to stop the loading of Skinny, a part of Asterisk server.
...

/etc/asterisk/sccp.conf

; Sample phone 'Wireless' on extension 2123
[SEP(MAC address of phone)] (ie [SEP000D288E45B7])
type = 7920
autologin = Wireless

context = sccp

[Wireless]
id = 2123
Label = Wireless
description = Wireless
context = default
callwaiting = 1
mailbox = 2123
callerid = "Wireless", <2123>

/etc/asterisk/extensions.conf

exten => 2123,1,SetCalledParty("Wireless" <2123>)

NOTES:

1. If the 7920 can call but the other person can not hear you this will most likely be an RTP problem. You may want to try some of the things I found to fix the problem:

A) Look at entry 127.0.0.1 in the Hosts file. For some reason I found on mine that I had the server name included with the entry.
B) If you have installed additional software for linux you may need to reinstall the support for SCCP.
