[Freeswitch-users] Shared Call Appearance and Transferring Calls on Cisco SPA504G

Fri Aug 24 23:39:40 MSD 2012

I am concerned that FS is trying to INVITE the calling user, ours 
doesn't do that.  Is it possible to send us a pcap trace of this?

In the mean time, here is how our SPA phones are configured. We are 
sharing 3 lines on multiple phones.  The following is the same on all 
phones.  If you want, you can configure the 4^th button as a private 
line (which isn't included here).  The 3 shared extensions are 121, 122 
and 123.
