I'm pretty new to opensips, I'm having a interesting problem, I use my
opensips for loadbalancing purposes I'm trying to place a call, and
from My linksys phone everything works fine, call comes into opensips
and opensips sends it to my asterisk system and call goes through
properly, from other phone (Aastra) Opensips accept the call, it even
sends it to the Asterisk but in never hits the asterisk server, can
anyone please review the 2 invites and let me know why second invite
gets lost, and how I can fix it

Here is the invite from the Linksys that worked
