[asterisk-users] SIP Channels

[Asterisk]

Hi there,

I'm trying to bridge 2 SIP channels together via AGI script. The AGI script is written in C#. The first 
caller would call in and be placed on hold and the second caller would call in and both the calls gets connected together.

But I am having problem with the second caller finding the first channel.

Can someone point me to the right direction?

thanks

Eric
