Is It Possible?

Asterisk Asterisk Support
1

Hi ,

I have cisco 7940 2-line phone working with Asterisk. I configured line 1 with extension 2138, line 2 with ext:3138. both extensions are working fine seperately.

Now i need following logic in extensions.conf

when line1 is busy, calls should ring on line2. if line2 also busy, then goto voicemail.

my current configuration is like below:

exten => _2138,1,Dial(SIP/${2138},15,r)
exten => _2138,2,Voicemail(u${2138})
exten => _2138,3,Hangup

exten => _3138,1,Dial(SIP/${3138},15,r)
exten => _3138,2,Voicemail(u${3138})
exten => _3138,3,Hangup

Can some one help me to write the code.

Thanks.

exten => 101,1,Dial(SIP/101,15)
exten => 101,n,Dial(SIP/301,15)
exten => 101,n,Voicemail(u${101})
exten => 101,n,Hangup

this SHOULD work…

EDIT: i just set up something similar, and when the phones are not registered, it jumps straight to VM.

that should work fine for you.

Hi ,
I have macro for my extensions. how do i edit MACRO to pass line sip-extension as argument. I tried some like below but, did not worked for me.

assume my ARG1 is 101, when 101 is busy, the call should go to 201 and then to VM.

[macro-ext]
exten => s,1,Dial(${ARG1},15)
exten => s,1,Dial(${ARG1+1000},15)
exten => s,2,Voicemail(u${ARG2})
exten => s,3,Hangup

Please help.

thanks
sekhar.

thats an interesting one.

If you are using all SIP lines (no iax2 or zap) you could do

exten => s,1,Dial(SIP/${ARG1},15)
to add +101 you need to put it as an expression, i THINK that would be $[${ARG1} + “101”] but i could be wrong. check voip-info.org…

(IE
exten => s,2,Dial(SIP/$[${ARG1} + “101”],20)

Hi IronHelix,

i tried calling from 2181 to 2138
It did not worked out, see below attached error

paste what you are currently using as the macro and the relevant other parts of extensions.conf to get that?

To make asterisk perform a calculation, you have to form it correctly…

Dial(${ARG1}+1000,15)

replace with

Dial(SIP/$[${ARG1} + “1000”],20)

to separate that-
$[${ARG1} + “1000”] becomes

${ARG1} + “1000” enclosed by $[ ], which tell asterisk that logic is going to be required.

Hi IronHelix,

I want to make sure that the express is working fine, so, i changed my macro to

[macro-ext]
exten => s,1,Answer
exten => s,2,SetMusicOnHold(default)
;exten => s,3,Dial(${ARG1},15) Commented this Line
exten => s,3,Dial($[${ARG1} + “1000”],10)
exten => s,4,Voicemail(u${ARG2})
exten => s,5,Hangup

So, when i dial 2138, the call is suppose to go 2138+1000=3138. 3138 is registered SIP Phone.
but i got below error.

-- Executing Macro("SIP/2181-b7906830", "ext|SIP/2138|2138") in new stack

– Incoming call: Got SIP response 500 “Server Internal Error” back from 10.250.10.201

Some where i read a conditional jump satements like exten => s,BUSY then GOTO ARG2 something likes this.
But first the mathematical calcualation should work to get this.

OR, is there a better way to automatically dial on to second Line in CISCO 79XX Phones?

Your help is really appreciated.

Have a nice long weekend.

ah i see the problem. ${ARG1} is ‘SIP/xxxx’, including the SIP/.

try this
exten => s,3,Dial(SIP/$[${ARG1:4} + “1000”],10)

${ARG1:4} strips the first 4 chars (SIP/) which leaves it with an exten #. The SIP/ is added again in the beginning.

Hope that helps!

below is my changed macro. I commented one line just to make sure the calculation is happening, but it seems still it needs some thing more.

[macro-ext]
exten => s,1,Answer
exten => s,2,SetMusicOnHold(default)
;exten => s,3,Dial(SIP/${ARG1},15)
exten => s,3,Dial(SIP/$[${ARG1:4}+“1000”],10)
exten => s,4,Voicemail(u${ARG2})
exten => s,5,Hangup

Thanks
Sekhar.

try removing the quotes from the “1000” so its just 1000…
