[Freeswitch-users] bridge to gateway overwrites "effective caller id" with "username"

[Christian Benke]

Hi!

I've recently started to configure a freeswitch for our new office pbx
and so far i like it very much(Coming from asterisk&openser with 2
years experience at a ITSP. Openser was nice but i didn't like asterisk
for several reasons, so i searched for a more stable and cleaner
alternative. Freeswitch looks _very_ promising and i'd wished i could
use it for more difficult demands than a simple office-pbx ;-)).

So far i had little trouble(Though our installation doesn't require
much), for PSTN-calls i'm using a SIP-Trunk provided by our ISP.

The only issue i have not resolved yet is setting the outgoing
DID("head"-number + extension, e.g. +4312345678 + 100).

The relevant part of the default.xml looks like this atm(where
+4312345678 is our "head"-phone-number without the extensions,
${caller_id_number} is a 3-digit extension, e.g.: 100):

<anti-action application="set"
data="effective_caller_id_number=+4312345678${caller_id_number}"/>
<anti-action application="bridge"
data="sofia/gateway/sip.myisp.at/${destination_number}"/>

I'd expect with this dialplan the effective_caller_id would be in the
"From:"-section of the INVITE, but it seems after the bridge it is
overwritten with the gateway-username i've defined in the
gateway-configuration in sip_profiles/external/.

So instead of:
From: "Desk Phone"
<sip:+4312345678100 at sip.myisp.at;transport=udp>;tag=U6yQUSta2c2Xg.
i get:
From: "Desk Phone"
<sip:p00xxxx.myisp at sip.myisp.at;transport=udp>;tag=U6yQUSta2c2Xg.
in the INVITE towards the sip-trunk.

I may not have grasped yet how proper debugging with freeswitch works,
however, in the console the last action i see, before the bridge to
sofia/external is created, is the setting of the effective-caller-id, as
expected(Do you want to see the whole output?).

I guess i don't necessarily need to register with the provider, as they
have configured the trunk for my ip-adress and i have theirs in
the ACL(inbound calls work flawless with the head-number+extension), so
maybe the registration is the reason why freeswitch does that
automatically?

It's probably a little issue, but i don't have the overview yet to
understand how this happens, maybe someone can point me to the right
place?
