Summary
-------

on every sip_alloc call a udptl structure is allocated if this dialog needs rtp. This could cause an easy dos condition and also needs much more memory than necessary cause this udptl structe is also allocated in handle_request_invite.

i can only think of a reinvite situation which could lead to a non allocated udptl structure but i dont think this can happen.


This addresses bug 18121.
