[SR-Users] crazy uac_replace_from

[Andres Moya]

Hi,
not sleeping second night.

I am trying to authenticate to sequence of SIP provider, if one fail - 
another.

I am calling uac_replace_from for each. 
uac_replace_from("sip:$avp(i:21)@$avp(i:24)");
first time it set ok:
From: <sip:andres.moya4 at sipdiscount.com>;tag=572ac509.
second time i am getting
From: 
<sip:andres.moya4 at sipdiscount.comsip:21100036838 at terrasip.net>;tag=572ac509.

grrrr.... is it a joke :)

Someone ... please  help
