Incoming/Outgoing headers

Hi, I’m brand new to PBX installation. I installed freePBX distro and got some help from my provider to set it up. They helped me set up the trunk, extension and outbound/inbound routes. There seems to be a problem with the headers that the provider was unable to help me with.

I am showing the following headers:
From: sip:[email protected];tag=0258a8ce
To: sip:[email protected];tag=as7920b8d1
** I added the x’s

but they are supposed to be like this:
"[email protected]" for incoming and outgoing.

Does anyone know how to change the headers?
