Is it possible to asterisk receive calls from other telephony systems like Cisco, Avaya if Asterisk provides a sip uri. The Cisco and Avaya will add the call to the SIP uri provided by asterisk so that they can add as a third party listener .
Could some one tell me is it possible and if yes, how its possible, I mean the settings?
Thanks @johnkiniston and @ambiorixg12 for your response. If I am starting with Asterisk to Asterisk calls, do we have any examples available? For example, I have two asterisk servers (S1 and S2), and a call is happening in S1 between CS1 and CS2. Can I transfer the call into S2 ?
You can use the Dial application to keep both Asterisk daemons in the connection, or the Transfer application to request the the other daemon to completely take over the call.
