[SR-Users] hadnling the IP extension calls freeing the PBX channel

[kiran bhosale]

hello ,
w  have PBX gateway along with kamailio. all calls are routed to pbx 
extensions. but  if it  happens to be an IP extrension we want  the  
kamailio to handle the speech without keeping the  PBX  channel  busy. 
if  its an analog  extension  then this channel can be busy but if its  
IP extension kamailio should handle the  speech itself. how is this 
possible ??

thanks in advance.
