Hi All,

I am using sipp for stress testing.I am routing calls from freeswitch to remote server's asterisk.

In asterisk call is answered and play music file.

I can make 100-200 calls but some of them are failing with MENDATORY_IE_MISSING in freeswitch.What should actually missing when freeswitch throw MENDATORY_IE_MISSING ?

I don't know why it is giving this error.

Can anyone please help me to solve this issue or can anyone assist me with this?
