Description (partial)

Symptom:
Incorrect phone screen display, when an incoming call is forwarded.
Specdifically, with the following config-

    alias 1 666 to  85004001  cfw  85004002  timeout 5

calling from external PSTN phone number ex:0612345678 To 4597, which is translated to 666, first rings the phone 85004001 and when it is ringing, screen phone display is OK.
But then when the call is cfw'd to the second phone ( 85004002 ),  the screen phone display :

    Forward 612345678 
    For 04929 (850...
    By 04929 (666)

is incorrect.

The number 04929 is corresponding to the external phone number mask in CUCM of an other IP phone.
The external phone number mask displayed is the field "name" or "description"  of the FIRST ephone recorded in the SRST router ( see "call-manager-fallback ephone-dn"  attached file),  whatever the redirect phone number used the mask is ALWAYS the one of the first ephone recorded.

Conditions:
1. SRST
2. alias command, under call-manager-fallback
