Obtain asterisk IP address from dialplan

Is there a way to capture the asterisk ip address from the dialplan? I would like to be able to dial a custom extension (like 1234), then have allison read out the current ip address.

Hi using the Header you should be able to get what you want

for example.

Code:

exten => 516,1,Noop(${SIPCALLID}) exten => 516,n,Set(FR=${SIP_HEADER(From):6}) exten => 516,n,Set(FR=${CUT(FR,<,2)}) exten => 516,n,Set(FR=${CUT(FR,@,1)}) exten => 516,n,Set(FR=${CUT(FR,:,2)}) exten => 516,n,Set(IP=${SIP_HEADER(Via):8}) exten => 516,n,Set(IP=${CUT(IP,P,2)}) exten => 516,n,Set(IP=${CUT(IP,b,1)}) exten => 516,n,Noop(${IP}) exten => 516,n,Set(UA=${SIP_HEADER(User-Agent):12}) exten => 516,n,Noop(${UA}) exten => 516,n,flite(Your caller i d is ${FR} and i p address is ${IP} Your user agent is a ${UA})

Thanks Ian,

Would this work for a phone connected to an fxs port? It looks like this depends on using local sip extension and should work well.
I have read that there are commands that can be used in the asterisk dialplan that can be interpreted as linux commands. I was hoping I could use this approach to achieve same functionality as one sees when setting up a sipura ata device - plug in an analog phone, dial a code/number and hear ip address.
I should have mentioned fxs port, but I had not even realized the approach you gave.

Thanks again.
