[cisco-voip] softphone from data to voice domain

[Ahmed -Y]

Thanks.


I've gone through plenty of cube documentation but didn't figure out if SIP
endpoint can terminate directly on CUBE. Most of docs discuss about sip
trunks between cube and cube/cucm/pstn etc. I read that cube support B2BUA
that mean remote sip device will terminate connect on cube and then cube
will initiate a separate session to internal destination sip server like
cucm using its own IP address as source and media will also flow in same
fashion as i draw below. As i mentioned i am not sure if cube can terminate
softphone like this. The purpose is to hide the internal topology. I don't
want to inject data routes in voice domain and vice versa.

softphone -----------------cube --------------- cucm

cisco ASA can act as proxy phone but question is can it hide the topology?

An other solution i am just thinking of but i am not sure if this is
possible and practical. Can you please confirm that if cisco latest
softclient like jabber or movi have built-in vpn capability? I am thinking
if i setup some asa firewalls on border of voice domain. when user open
jabber or movi application, it automatically establish vpn with these
border firewalls and get dynamic ip address from firewall from voice ip
ranges. In otherwords the softphone will be part of voice domain after vpn
is established. whats your thoughts

Regards
