Hello, I've done a bit of research, though obviously in the wrong places. :) I'm looking to set up some type of distinctive ring for SIP phones based on the context in which the SIP phone is being called from. If that sounds confusing it isn't. I have two FXOs connected to POTS, so in essence a caller could be dialing us at one of two phone numbers. Each of those FXOs has its own context in extensions.conf. The contexts essentially grab the incoming call and ring a bunch of single line SIP phones. If no one answers then the call is sent to voicemail depending on the number that the caller dialed. The problem is that when the SIP phones ring, there's no way for us humans to tell which number the caller actually dialed. My initial thought was to make some type of distinctive ring to the SIP phones to indicate which number the caller dialed, much in the same way that the telco does it when someone has the distintive ring service. Another idea would be to set the callerid on the SIP phones to indicate which line was dialed. The drawback there is that we lose the incoming callerid from POTS. Maybe set one of line of the callerid to the incoming line and leave the other as the callerid number? Does anyone have experience with setting distinctive ring in SIP in such a way? Steve
exten => s,1,Wait(1)
exten => s,n,Set(Var_Alert=${SIP_HEADER(Alert-Info)})
exten => s,n,GotoIf($["${Var_Alert}" =
"<http://127.0.0.1/Bellcore-dr3>"]?2,1)
;goto ext 2 if distinctive ring
exten => s,n,Dial(SIP/1)

Hello,
I've done a bit of research, though obviously in the wrong places. :)
I'm looking to set up some type of distinctive ring for SIP phones
based
on the context in which the SIP phone is being called from. If that
sounds confusing it isn't.
I have two FXOs connected to POTS, so in essence a caller could be
dialing us at one of two phone numbers. Each of those FXOs has its
own
context in extensions.conf. The contexts essentially grab the
incoming
call and ring a bunch of single line SIP phones. If no one answers
then
the call is sent to voicemail depending on the number that the caller
dialed. The problem is that when the SIP phones ring, there's no way
for us humans to tell which number the caller actually dialed.
My initial thought was to make some type of distinctive ring to the
SIP
phones to indicate which number the caller dialed, much in the same
way
that the telco does it when someone has the distintive ring service.
Another idea would be to set the callerid on the SIP phones to
indicate
which line was dialed. The drawback there is that we lose the
incoming
callerid from POTS. Maybe set one of line of the callerid to the
incoming line and leave the other as the callerid number?
Does anyone have experience with setting distinctive ring in SIP in
such
a way?
Steve

I also do this to set the called ID and not loose the actual CID: exten => s,n(prefixCID),Set(CALLERID(Name)=L1_${CALLERID(Name)}) or exten => s,n(prefixCID),Set(CALLERID(Name)=L2_${CALLERID(Name)}) Ira
