New subject: [Kamailio-Users] trying to use call park for similar a music on hold

30 Dec 2008

Hi list, I am trying to make work to the parking of calls with
openser and asterisk, which I want to do is when two UAC are in the
middle of a call one of them can transfer a call with *700 and this is
sent to asterisk to the extension by default...

the problem here is that when I make the transfer to the extension 700 the asterisk it
doesn't return it to the extension that I originate the transfer, the call it returns
to the extension in delay ..

I can see when I make the transfer in the SDP that the openser puts me  c=IN IP4 0.0.0.0 ,
but asterisk doesn't return the call to the extension that I originate the transfer
