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@sip.myisp.at;transport=udp>;tag=U6yQUSta2c2Xg. i get: From: "Desk Phone" <sip:p00xxxx.myisp@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? Cheers Christian
