Hi,
we have a problem with a German SIP Provider (Sipgate). They need a special SIP Header information to send the CLI number. We can do it with a Asterisk Server like :
SipAddHeader(P-Preferred-Identity: sip:[email protected])
How can i do it in Office Serv v4.60 / v4.70 ?

... I change the flag "P Asserted ID Use" 5.2.13 tu Alternate, but it doesn't send the correct CLI number.

Compare the wireshark traces from asterisk to samsung see what the different settings in the samsung do.
