Hi All, I have a problem with my FSW instance (version 1.0.7 on RHER 5.6 64bit). Freeswitch does not allow to pass 'to-tag' or 'from-tag' in addition to "Replaces=" while deflecting a call. This action works: <action application="deflect" data="sip:conf_t0_2@10.79.21.108?Replaces={sip_call_id}" /> The session I try to deflect is set from Broadworks 16 via ALU IMS core (ISC 5450). Our supplier claims that to successfully handle REFER from FSW, Refer-To header should include also 'to-tag' and 'from-tag'. Example I got looks like this: Refer-To: sip:conf_t0_2@10.79.21.108?Replaces=1387BD211B831526@172.16.10.114;to-tag=1728507150-1263982355499;from-tag=xUDOxkDMyYD But when I set action to: <action application="deflect" data="sip:conf_t0_2@10.79.21.108?Replaces=${sip_call_id};to-tag=${sip_to_tag};from-tag=${sip_from_tag}" /> in cosole log I can find: EXECUTE sofia/internal/+48399500015@neofon.tp.pl deflect(sip:conf_t0_2@10.79.21.108?Replaces=BW131151222041111-105561828@10.8.80.100;from-tag=139928099-1320408711222-) and FSW freezes until other side issues BYE. Is this a problem on my side (like different action is needed or some vars should be set)? Or is it related to FSW/mod_sofia (source)? TIA for your help or suggesions, Mariusz
