[Serusers] To enable call transfer on Server side

Roman, 

I'm been trying to do something simple using Cisco GW's I was wondering how
you got it to work?

1. Person A calls person B

Person A ---> [PBX] --> [SIP GW] --> [SER] --> [SIP GW] --> Person B

2. Person A calls person C and second line. (Person B is on Hold)

Person A ---> [PBX] --> [SIP GW] --> [SER] --> [SIP GW] --> Person B 

3. Now we want to be about to Connect person B and person C, with out Person
A needing to be on the line.

Person B --> [SIP GW] --> [SER] --> [SIP GW] --> Person C

-Greg

All,

Apollogize for previous email.
I did more tests and got ATA working.
problem was newet SW. I changed to 2.15
and it is working now.

But I still have problem with c5300 (c3600)
to accept REFER.

so my new question is:
Hase anybody working enviroment
where calls are comming through PSTN
to c5300 (c3600,c2600) via ISDN and forwared through SIP (SER)
to ATAs and having working calltransfer betweens ATAs ?
any suggestion on IOS and/or cisco config ?

thanx,
