[reSIProcate] Assert in DialogSetId, issue with from to tag

[Mandeep Ahuja]

Hi,
I really need help on this one.
My phone would randomly crash with the following assert
"resip::DialogSetId::DialogSetId(c onst resip::SipMessage &): Assertion 
`msg.header(h_From).exists(p_tag)' failed" Now I looked at the code and 
there are no comments or no error checking. Can someone tell me how do i 
get around this situation, or why is this happening, or simply what 
should I do to fix it.
thanks
I appreciate any help

Mandeep
