2 asterisk server Ignore callfrom context

Dear People,

I have 2 asterisk machines which are sharing the same real-time SIP database.

Between the servers I have a SIP channel, the sip peers are ok!
The problem is when the sip channel [100001] fails over form server .120 to server .121 via sip channel [asteriskservers] Asterisk is using the Context off the Caller from[100001], in this case context 121210 and not context of the Sip channels [asteriskservers] asteriskservers.

Is there a way to ignore the Caller form when it’s uses the [asteriskservers] sip channel?

This channel exist on both servers
