Manipulating Sip header in Freeswitch - "Status 500: Too many Allow-Event"

I am using a local company's support for call out, and they would not tell me
the device name nor the details at their end, only the error and the reason for
it being too many allow-events.

however, i had tested the same system on my local setup with spa 3102 and it
worked fine. i dont know how to change the sip header part, and the error
remains "Status 500: Too many Allow-Event". is there a conf file i need to
change, because i dont want to go into the packet making problems.
