Thank you Raviprakash for your reply. 

 I have my system setup as you described, however, I am experiencing difficulty with the actual call transfers.  
The problem is that Asterisk is not "replacing" the call when it receives a REFER request to connect.


Are you using this setup? 


I  have configured openser to relay calls made to  ruri 700-720 to asterisk running on localhost:5069


Call flow:

phoneA --------call------> phoneB

PhoneB answers

then  PhoneB -----transfer --------> asterisk (700)

asterisk answers and plays the parking location (701)

PhoneB (press transfer again) -----------REFER ---------> phone A

PhoneA -----------invite with referred-by header-------> asterisk

At this point, 

Asterisk  <---------------connected and plays parking lot 702 -----------> phoneA

Asterisk <-------------still connected -------------------> phoneB


This was a specific example but this transfer problem is not limited to call park only. It happens any time asterisk is the second party called in call transfer.

Thanks in advance for your help.

Hi
OpenSER doesn't the Park calling Feature ,

you Should forward the Call to Asterisk Server,

UA--------->openser---------->Asterisk

in asterisk configuaration directory ...> /etc/asterisk.
in that directory , see the feature.conf and followme.conf (asterisk1.4).

see  in the www.asteriskguru.com

Hi All.
       Has anyone implemented call park / pickup feature using
OpenSER and asterisk?  Or maybe OpenSER and something else ?

  Any help / suggestion is greatly appreciated.
