[Serusers] Re: How to change Caller ID in FROM field ?

[lawrence k.y. lin]

Steve,

    Thanks for your help regardin the Caller ID in FROM field in your 
previous email.
    It was working with the your suggestion for 'replace' to hard-code the 
FROM field.
    I would like to extend it to any users which has a Caller ID (normal 
phone number) mapping to SIP account and stored in Postgres database.
    When someone calls from SIP device, I use exec_msg to call the external 
C program which retrieves the Caller ID related to this SIP account. The 
problem is how to pass this data back to SER and put into FROM field ? 
Please advise,

   Thanks and Regards,

Larry
