I have two sites interconnected via SIP Trunk Peer To Peer
One is S100 and the other S412.
My problem is as follows, everything works perfectly everyone dials its own extensions and remotely on both sites .
When site B calls site A the SIP phone on SITE A displays the caller id NAME and extension number of extension from SITE B.
But when i dial from SIP phone from SITE A the extension back on site B it shows on my sip phone on SITE A only the extension number when it dials (call works fine).
I want while i am dialing from my SIP phone from SITE A for it to recognise the remote site B's extension name and number and show it to me not just the number.
Is this possible?
Thank you in advance
