Answer

Yes, via SIP PUBLISH messages. When the digits/characters to dial are being typed in, the phone sends a PUBLISH request to the proxy. Assume we have typed in "1" and "0":

PUBLISH sip:101@192.168.0.1:5060 SIP/2.0
...
CSeq: 1 PUBLISH
...
Event: number-guessing
... 
Number: 10
Max-Hits: 3

The proxy sends back three alternatives attached to the reply:

SIP/2.0 200 Ok
...
CSeq: 1 PUBLISH
c: application/number-guessing
l: 136
