<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Ok. Our upstream provider, IDS Telecom, will not let us set
outbound caller ID to anything we want, like we used to be able to do with
Expedius. We have to provide them with a list of any numbers we want to be able
to set outbound caller ID to. So we have to give them a list of all our
DID’s, from them, from Expedius, from VoicePulse, etc. etc. and
it’s quite tedius, but we’ve been ok with it for now.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>However, we use Cisco 79xx phones. If we use the
“CFwdAll” option on the phone, to forward calls, the phone will see
the incoming call and redirect it to the call forwarded number, fine no
problem. However, the phone (or asterisk) tries to change the outbound caller
ID to the callers caller ID, this way the person receiving the call will know
who’s calling them. However, IDS will not recognize this number and
won’t let us set our caller ID to it so it will use the fall-back caller
ID number, which is our company’s main number.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Just got a complaint from a customer who’s upset that
when he call forwards to his cell phone, whenever a call comes into his cell
phone (relayed through their office phone), the caller ID shows our number, and
not his office number or the callers number.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>If they picked up the phone, placed a call to their cell,
the right caller Id would be provided, as I have this set as their caller id in
sip.conf but only when the phone tries to do a blind transfer will
it attempt to change or alter its normal outbound caller id, which seems to
override what’s in asterisk’s sip.conf file.<o:p></o:p></span></font></p>

any “unknown” outbound caller id numbers, just out of area. So
when a call is forwarded through a Cisco, their cell will say “Out
