Incomming Calls going to context from-sip-external

Hi,
I have a Unify PBX and connected the FreePBX as a SIP Client.
I FreePBX I used Trunk to register the FreePXX to the Unify PBX as a SIP Extension.13

13:[email protected]/13

From The UnifyPBX I can now make calls to 13, but the incomming call on the FreePBX are going to extension from-sip-external intstead of extension from-trunk:

Thanks dor help.

FreePBX is (correctly) set up to not allow anonymous connections, but your Unify isn’t set up correctly in the FreePBX trunk. You need to add the IP to the trunk config.
