Hi Gang I use: lookup_to_dset(), t_load_contacts(), t_next_contacts() to gather contacts for parallel forking (like for a hunt group). After that I use $cnt($xavp(tm_contacts)) to find the number of branches which would be created. But $cnt($xavp(tm_contacts)) seems to always be 1 no matter how many branches I get in route(RELAY). What am I doing wrong? Is there another PV I could use? Background: When a 100rel is supported by the originating device, the destination devices might all reply 180 RINGING with 100required, same rseq but different ToTags. The originating device would require to reply PRACK to each of those ringing and it looks like MANY originating devices (especially commercial SBC) do NOT consider the ToTag but ignore any subsequent 180 RINGING with same CallID and rseq causing such forked calls fail. So if I have > 1 branches, I would like to exclude_hf_value("Allow", "PRACK"); exclude_hf_value("Supported", "100rel"); -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________
