They send patches out by email? Who thought of this brilliant idea? "Hmm, let's teach our users not to be cautious."
/me wonders when someone on linux is gonna install a "patch" that compromises their system cause some email said so.... -Michael -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, November 10, 2004 1:54 PM To: [EMAIL PROTECTED] Subject: [Asterisk-Users] Broadvoice asterisk patch Just received this from broadvoice, anyone know if this patch will become part of the CVS tree? ------------------ THIS PATCH MUST BE APPLIED WITHIN 5 DAYS OF RECEIVING THIS E-MAIL OR YOU WILL RISK THE POSSIBLE SUSPENSION OF YOUR BROADVOICE SERVICE. WE APOLOGIZE FOR ANY INCONVENIENCE THIS MAY CAUSE BUT REQUIRE THIS PATCH IN ORDER TO MAINTAIN UNINTERRUPTED OPERATION. Dear Asterisk-Using BroadVoice Customer, BroadVoice has been working very hard in recent months to become a market leader in VoIP service.? As a part of that effort, we have made a concerted effort to facilitate interoperability with as many different SIP devices as possible -- including Asterisk.? While BroadVoice does not directly support Asterisk and will not be able to field specific question on your Asterisk set-up we are doing our best to assist. Unfortunately, the SIP channel in Asterisk has a number of serious issues which make it very difficult for BroadVoice to accommodate Asterisk.? One of these issues, a bug with the Asterisk registration system, is causing an unacceptable load our systems. BroadVoice has hired Olle Johansson and Steve Sokol (the AstriCon team) to work out a solution to the issue.? Attached is a patch that, when applied, will reduce the undue strain on the BroadVoice systems by properly handling registration for Asterisk servers located behind NAT gateways.? We ask that you take a few minutes and patch your server using the following instructions. This patch applies both to the current CVS Head and the Stable 1.0 versions of Asterisk.? If you are running an older version of Asterisk, please update your system to at least 1.0 prior to applying this patch (or you can hack the patch into place in the old chan_sip.c if you feel like it). Note that this patch will be incorporated into the Asterisk CVS at the earliest opportunity.? However, due to the serious nature of the issue we ask that you patch your servers immediately. -= Patch Instructions =- 1.? Copy the patch to /usr/src/asterisk/channels/ (or wherever you store your Asterisk source image. # cp /usr/bob/sip_patch.diff /usr/src/asterisk/channels/ 2.? Apply the patch using the following command: # cd /usr/src/asterisk/channels # patch chan_sip.c sip_patch.diff 3.? Re-compile the SIP channel by executing 'make' in the /etc/asterisk directory. # cd /usr/src/asterisk # make 4.? Install the newly compiled SIP channel with the 'make install' command. # make install 5.? Restart Asterisk to enable the patch as follows: # asterisk -rx "restart when convenient" This patch will update the Asterisk channel to cache and properly handle registration messages.? Please review the code and, if you have any suggestions, send comments to the author at [EMAIL PROTECTED] -= BroadVoice Configuration Notes =- Because Asterisk does not have outbound proxy support, you need to make a few other changes to make Asterisk work well with BroadVoice. 1.? Find the closest BroadVoice proxy using the 'ping' utility. proxy.dca.broadvoice.com??????? 147.135.0.128 proxy.lax.broadvoice.com??????? 147.135.8.128 proxy.mia.broadvoice.com??????? 147.135.4.128 # ping proxy.lax.broadvoice.com PING proxy.lax.broadvoice.com (147.135.8.128) 56(84) bytes of data. 64 bytes from proxy.lax.broadvoice.com (147.135.8.128): icmp_seq=1 ttl=47 time=41 ms 64 bytes from proxy.lax.broadvoice.com (147.135.8.128): icmp_seq=2 ttl=47 time=31 ms 64 bytes from proxy.lax.broadvoice.com (147.135.8.128): icmp_seq=3 ttl=47 time=58 ms # ping proxy.dca.broadvoice.com PING proxy.dca.broadvoice.com (147.135.0.128) 56(84) bytes of data. 64 bytes from proxy.dca.broadvoice.com (147.135.0.128): icmp_seq=1 ttl=47 time=141 ms 64 bytes from proxy.dca.broadvoice.com (147.135.0.128): icmp_seq=2 ttl=47 time=312 ms 64 bytes from proxy.dca.broadvoice.com (147.135.0.128): icmp_seq=3 ttl=47 time=258 ms Which ever proxy is closer (has a shorter ping time) is the proxy you want to use. 2.? Make the proxy your default by adding it to your /etc/hosts file. cd /etc vi hosts If say dca is closest add a host entry that looks like: 147.135.0.128?????? sip.broadvoice.com of course replace 0.128 with the ip of the "closer" proxy 3.? Configure Asterisk to connect to BroadVoice: ?From the sip.conf file: register => 8165551212:[EMAIL PROTECTED]/8165551212 [broadvoice] type=friend username=8165551212 fromuser=8165551212 secret=MyPa55w07d host=sip.broadvoice.com port=5060 context=broadvoice fromdomain=sip.broadvoice.com canreinvite=no dtmfmode=inband insecure=very permit=147.135.0.128/32????? ; or of closer proxy qualify=yes Note that having the IP address in the host file alters the way SIP recognizes incoming calls from BroadVoice (before, Asterisk would not tie incoming BroadVoice calls to the BroadVoice peer).? For this reason you have to add the "insecure=very" to allow Asterisk to accept calls, then add the permit=147.135.X.128/32 to limit calls to only the valid proxy. Calls from BroadVoice will end up in the 'broadvoice' context in extensions.conf.? You will need to add an entry for your own phone number in the context and direct that to whatever device you want: [broadvoice] exten => 8165551212,1,Dial(SIP/100|30) exten => 8165551212,2,VoiceMail([EMAIL PROTECTED]) exten => 8165551212,102,VoiceMail([EMAIL PROTECTED]) Alternately you can leave the phone number off the end of the 'register' statement in sip.conf and Asterisk will set it to 's' automatically.? In that case you would want the following: exten => s,1,Dial(SIP/100|30) exten => s,2,VoiceMail([EMAIL PROTECTED]) exten => s,102,VoiceMail([EMAIL PROTECTED]) Send outbound PSTN calls to your BroadVoice account as follows: [outgoing-context] exten => _.,1,Dial(SIP/broadvoice/${EXTEN}) exten => _.,2,Congestion() Thanks for helping to make Asterisk and BroadVoice work together, and thank you for your business.
