[OpenSIPS-Users] Call pickup

[duane.larson at gmail.com]

I was thinking about this last night and with the Snom Phones I am able to  
do the following.

I know how to cancel the first call to the PhoneB and I am thinking that I  
can cancel the call that PhoneC does when it wants to do a Call Pickup. The  
thing I am not sure about is how on the first call to add a branch to  
PhoneCs URI. How can I pass PhoneC's URI info to the first call so that I  
can add the new branch?
