RE: [Serusers] Modifying "From" header field of an INVITE message

Asterisk Operational Note: From Asterisk, try something similar to this: exten => _1XXXXXXXXXX.,1,SetCIDNum(+1${CALLERIDNUM}) exten => _1XXXXXXXXXX.,n,Dial(SIP/+${EXTEN}(a)ser.mydomain.com) This assumes you have ten digit North American caller ID digits, and that you need to hand numbers to Level3 like "+13015551212" for both ANI and DNIS. SER Development/Usage Note: While I agree that changing the "From:" is generally a bad idea, there certainly are instances in which is is a desirable thing for a SIP proxy to do. The instance below is a good example. Other examples are when the recommended privacy options are not used, so despite privacy settings elsewhere in the headers the "true" Caller ID is shown on the remote side. The only way to avoid this would be to not include the origin AOR on the outbound call. Of course, to process replies correctly, it may be necessary to mangle the headers in the inverse manner on the way back in... but that level of voodoo is left to the administrator. I agree that a b2bua is a way to do this - it may be necessary to keep state in that manner. (specific note: Asterisk _is_ a glorified b2bua.) However, it seems natural that all headers should be subject to modification if required within the proxy - not always is it required to keep state, as in this case. Is it truly the case that SER does not allow re-formatting of the From: header in any way? JT At 4:46 PM -0800 on 2/5/05, <scm-j(a)nuntius.com> wrote:
