Hi,

i am using GIT-Trunk-Version (latest). And that version does not
contain the fix, e.g.:

http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sems;a=blob;f=core/AmSdp.cpp;h=7165242af2e4cad010ac4f47fa82f9523c65bd57;hb=HEAD

Can someone from the SEMS-Team apply the patch to GIT Trunk?

Thanks for pointing that out,
Carsten
