Hello list, I am afraid I am asking something stupid but I cannot find a way to do this cleanly, so here it goes.... I am retrieving values from a db using either carrierroute or mtree modules to send a 302 to my softswitch. It expects the message as: SIP/2.0 302 Moved Temporarily Via: SIP/2.0/UDP 134.111.48.66:5060;branch=zgfdgdfgf2491b5437 Contact: <sip:989897@X.X.X.X;rg=4003>;q=0.2 Contact: <sip:989897@X.X.X.X:rg=321>;q=0.8 To: <sip:989897@X.X.X.X:5066>;tag=1 ..... Where the important things are the rg: those are the trunks in the SS) and the q (probability) and there can be multiple rgs for the same prefix (2 in this example) My idea was to keep in the db something like this: Prefix:98 Route:4003,0.2|321,0.8 And then inject those values in the contact header, but I am having a hard time finding the right way to do it. Is there any way to do it without calling the perl module? Many thanks, A
