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(a)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

<There shouldn't be anything happening to the From address on the

<Anyone have any ideas?
<I have attached a ethereal dump of the call setup.
