Anybody have an idea what would cause this error:
252049195[SIPS:007]In TranscMsgReceivedEv, Failed to sip_Handle_OptionsMessage
I have a few Grandstream ATA's connected to this 7100system.

My wild guess would be that the Grandstream devices are sending SIP OPTIONS messages which the PBX doesn't know what to do with. It might not cause any problems unless the Grandstreams are dropping to a state where they don't allow outgoing calls due to lack of response to their OPTIONS packets.

I agree with what Tone has said, based on the error message, I never saw any documentation on how-to decode those messages.
We were told it was something for the engineers in Korea

I can't remember if the OS7000 responds to options messages.
I would just disable it on the Grandstream ATA's as they'll be registering, make sure the registration timer isn't high.

I use options message when doing sip trunks/peering on the OS7000 to keep the NAT session open in the router so there are no issues with incoming calls
