Hi there,

   We have a Postgres Database to store the users' informations before we use Openser. To integrate between Postgres and Openser, we write external C programs and call them from Openser with exec_dset function.
   The issue we have now is with the Caller ID. When the user makes a call to PSTN number from SIP devices (soft phone or hard phone), the telco carrier requests us to send a numerical Caller ID, not the SIP format (such as john.dow@abc.com). What I am doing is to add the Caller ID field into the Postgres for each user and write a C program to query the Caller ID field, then Openser calls it with exec_dset functioin.
    However, I did not find a way to define a variable in Openser to store this Caller ID and pass it to uac_replace_from function.
    Appreciate for any suggestions.

Jeff,
    You mentioned that you replaced the From Header, may I ask how you do it ?
Thanks and Regards,

Don

<I seem to have an issue with uac_replace_from.

<I am using openser as a media proxy. For invites I replace the numbers
<with leading 0's with 61 for Australia and forward the call to our LCR
<box which then forwards the call to the correct voice to pstn gateway.
<I am trying to use uac_replace_from to set the from address so the
<callerid appears correct on the outgoing calls.

<This seems to work fine for the INVITE request, but on subsequent PRACKs
<and ACKs (which just get loose routed), something strange happens to
<the from address.

<On invite, the From get re-written:

<From: Jeff <sip:610089001@proxy.sipone.com;user=phone>;tag=1790577941
<to
<From: Jeff <sip:0892209080@sipone.com>;tag=1790577941

<For the PRACKs and ACKs, this happens:

<From: Jeff <sip:610089001@proxy.sipone.com;user=phone>;tag=1790577941
<to
<From: Jeff
<<\032\317\352S\232\222B\230\234K\231*BV\300\030\303\332\ah\303\306i\365\005\016\200\250\000\000\230\016\200\252j\200\002`\000\000\016>;tag=1790577
<941

<There shouldn't be anything happening to the From address on the
<(PR)ACKs at all.

<Anyone have any ideas?

<I have attached a ethereal dump of the call setup.
