[asterisk-users] addressing peers dynamically

[Danny Nicholas]

I had a similar problem (I work on 3 lans; when my firewall is down, the two
non-native lans are unaccessible)  I wrote an AGI to execute "sip show
peers" and process only the ones that return OK and pass my peer numbers to
the AGI like this -

[dialall]

Exten => s,1,AGI(sipcheck.agi,100,200,300)

exten => s,n,Gotoif($[ "${LEN(${DIAL-100})}" != "7"]?dialall,s,4)

exten => s,n,Set(TODIAL=${TODIAL}'&'${DIAL-100})

exten => s,n,Gotoif($[ "${LEN(${DIAL-200})}" != "7"]?dialall,s,6)

exten => s,n,Set(TODIAL=${TODIAL}'&'${DIAL-200})

exten => s,n,Gotoif($[ "${LEN(${DIAL-300})}" != "7"]?dialall,s,8)

exten => s,n,Set(TODIAL=${TODIAL}'&'${DIAL-300)

exten => s,n,Dial(${TODIAL},40,i,KktTm)

hi,
in my small setup (just for home usage) i have 5 phones configured. but only
2 of them are permanent connected to asterisk.
nevertheless i want to address beside those two phones other peers if
available. nowadays i address them always, resulting in error messages:
Unable to create channel of type 'SIP' (cause 20 - Subscriber absent)
Is there a way to avoid those messages? I think about something like a
virtual queue (please excuse if the wording is incorrect, i am not in too
deep to asterisk, i am more firm with genesys) that is addressed and peers
are registering to that queue.
is that the right path, or am i barking the wrong tree?

regards,
andre
