Re: [asterisk-users] Asterisk Behind Firewall
Hi, I have used a sonicwall Firewall, it has a sip transformation feature. It is necessary to use a firewall to protect your server Best Regards, Madushan On Mon, Jan 4, 2016 at 11:45 PM, IPN Commwrote: > I was wondering if anyone can give me any pointers or insights of whether > or not to have an asterisk server behind a firewall. > > I have always ran Asterisk on a public IP but was wondering if I should > move it to a local IP behind a firewall. > > I am looking to set up a location with 300 SIP phones. > > Normally, I would put the Asterisk server on one public IP and let the SIP > phones get DHCP from a router on a different IP and they would register to > the Public Asterisk server from that IP address. > > Should I move the asterisk server behind the same router? > > If so, how should the server be set up and what is the best > router/firewall hardware to accomplish this environment? > > Thanks, > -H > > -- > _ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > New to Asterisk?

[asterisk-users] Forwarding call if extension busy
Hi and happy new year! My question: - two extensions: and - an active call on - incoming calls to should be forwarded to (call advice!) and I know how can I forward an incoming call to more than an extension, but I have no idea how can I get the information, that has already an active call... I think, I need something like: exten => _,1,Verbose(2,Incoming call for - [${CALLERID(num)}]) exten => _,n,GotoIf( ?busy) exten => _,n,Dial(SIP/,19,RcxX) exten => _,n,VoiceMail(,us) exten => _,n,Hangup exten => _(busy),n,Dial(SIP//,19,RcxX) exten => _,n,VoiceMail(,us) exten => _,n,Hangup Well, the problem is the second line, of course... Of course the extension is NOT "really busy", since the phone can support more active channels, but I hope I explained my problem... Any suggestion?

Re: [asterisk-users] Forwarding call if extension busy
Zitat von Kevin Larsen: Hi Kevin For instance, my customer service department has this thing against ever having their phone ring a call while they are already on a call, so for these special little snowflakes, I have the following line: same => n(voice),GotoIf($["${DEVICE_STATE(sip/${EXTEN})}" != "NOT_INUSE"]?voicebusy) I think, this is EXACTLY what I'm looking for... I'll try this evening! Thanks Luca Bertoncello (lucab...@lucabert.de) -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Thanks Luca Bertoncello (lucab...@lucabert.de) There may not be a general solution as the end points can accept more than a single call themselves as described by yourself, i.e. the phone may not be in a busy state unless the max. number of calls has been reached or a call has been actively rejected. In that case you might put another Dial just after the first Dial application. If there is still no answer, VoiceMail gets called. You need to configure your phone to accept only a single call. Another approach would be to check from within Asterisk whether a particular endpoint has already active calls and Dial() as required, i.e. one would delete the phones with active calls from a given list. Since there is no real "busy" condition, this seems to be a cleaner approach. At first you should be able to describe exactly which behavior you want. jg -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

For instance, my customer service department has this thing against ever having their phone ring a call while they are already on a call, so for these special little snowflakes, I have the following line: same => n(voice),GotoIf($["${DEVICE_STATE(sip/${EXTEN})}" != "NOT_INUSE"]?voicebusy) Basically, this little line looks at the extension and if it shows anything other than free (NOT_INUSE), it jumps to the voicebusy line in the dialplan. The voicebusy line just hits voicemail directly. You can use this same idea to branch your logic and handle a variety of situations. In my case, I only want to actually perform the dial if the phone is currently not in use, so my logic was fairly simple.

[asterisk-users] Asterisk Behind Firewall
I was wondering if anyone can give me any pointers or insights of whether or not to have an asterisk server behind a firewall. I have always ran Asterisk on a public IP but was wondering if I should move it to a local IP behind a firewall. I am looking to set up a location with 300 SIP phones. Normally, I would put the Asterisk server on one public IP and let the SIP phones get DHCP from a router on a different IP and they would register to the Public Asterisk server from that IP address. Should I move the asterisk server behind the same router? If so, how should the server be set up and what is the best router/firewall hardware to accomplish this environment?

Re: [asterisk-users] Asterisk Behind Firewall
Both work. If you have enough IP addresses to dedicate one to your Asterisk server, that removes one node in the path from the world. You will need a firewall on the Asterisk server to protect it from outside meddling. If you can put the Asterisk server on the same network as the SIP devices (using a second NIC) that should help performance. Is the SIP network on the same network as your internet/data LAN?
