[Freeswitch-users] no display-update after transfer

[wiebittewas]

when using transfer on the phones, the call will be successfully transfered to the other phone, but it doesn't display the orinal caller-id, but keeps instead that id of the transfering phone.

as I can see on the net, the refer-to info from the transfering phone to the server looks good:

	REFER sip:mod_sofia at 192.168.1.1:5060 SIP/2.0
	Via: SIP/2.0/UDP 192.168.1.3:5060;branch=z9hG4bK850879522;rport

	Referred-By: <sip:24 at pbx.priv>
	Allow: INVITE, ACK, OPTIONS, CANCEL, BYE, SUBSCRIBE, NOTIFY, INFO, REFER, UPDATE, MESSAGE
	Content-Length: 0

and freeswitch sends an ACCEPTED-msg for this REFER



in the freeswitch.log I found entries like:

[ALERT] sofia.c:1198 sofia_update_callee_id() sofia/internal/u620 at 192.168.1.4:5060 Same Callee ID "Outbound Call" <20>

which leads to the situation, that no display-update will be send.

unfortunately the REFER-handling of freeswitch doesn't seem to offer any possibility to intervene for debugging the available variables, so I have no idea, why freeswitch sees equal callee-ids.

any suggestions how to look deeper or how to modifier the variables so that the update will be sent?

regards
