Basic Calls
---------------------------------------------------------------
1) Direct call: UA1-->UA2
# caller UA (UA1)
uac -f config\a.cfg
# callee UA (UA2)
uac -f config\b.cfg

# tests:
# UA2 accepts the call 
# UA2 refuses the call 
# UA1 cncels the call 

# caller UA (UA1) with automatic dialing 
uac -f config\a.cfg -c 127.0.0.8:5080
# callee UA (UA2) with automaitc answer (example, after 2secs)
uac -f config\b.cfg -y 2

# graphical UA
uaw -f config\a.cfg

2) Registration (with/without authentication): UA-reg->Registrar
# registrar + stateless proxy
proxy
# registering UA (for 30min)
uac -f config\a.cfg -g 1800

# tests:
# Registrar does not require digest authentication ('do_authentication=no' in server.cfg) 
# Registrar does require digest authentication ('do_authentication=yes' in server.cfg) 


3) Call through Destination Proxy (Registrar+Proxy): UA2-reg->Registrar , UA1-->Registrar/Proxy-->UA2
# registrar + stateless proxy
proxy
# callee UA (UA2) registered
uac -f config\b.cfg -g 1800 -y 0
# caller UA (UA1) with automatic dialing 
uac -f config\a.cfg -c bob@127.0.0.8

# registrar + statefull proxy
sproxy

4) Call through Destination Proxy on-route: UA2-reg->Registrar , UA1-->Registrar/Proxy-->UA2
# set on-route parameter in server.cfg
# then, repeat steps of (2)


5) Call through Destination Redirect (Registrar+Redirect): UA2-reg->Registrar , UA1-->Registrar/Redirect-->UA2
# use redirect instead of proxy
redirect


6) Forking calls at the Destination Proxy: UA21-reg->Registrar , UA22-reg->Registrar , UA1-->Registrar/Proxy-->UA21
# register two UAs (UA21 and UA22) on S2 with the same AOR (i.e. the From URL) 
uac -f config\b.cfg -g 1800 
uac -f config\b2.cfg -g 1800
# caller UA (UA1) 
uac -f config\a.cfg -c bob@127.0.0.8

# try with both Proxy (proxy) and StatefulProxy (sproxy)


7) Call through Outbound Proxy and Destination Proxy on-route: UA2-reg->Registrar , UA1-->Proxy-->Registrar/Proxy-->UA2
# set outbound_proxy parameter in a.cfg
# then, repeat steps of (2)

# try with both Proxy (proxy) and StatefulProxy (sproxy)


8) UAs and servers on different hosts 
# the same as (6) but with UAs and proxies on different hosts; example: UA1 and S1 on host1 and UA2 and S2 on host2


9) Server registrations: UA2-reg->S21 , [S2(k-1)-reg->S2k ,] UA1-->S2n-->..-->S22-->S21-->UA2
# starts two or more servers (Registrar/Proxy), e.g. S21 and S22
# register UA2 with S21 as in (2)
# create a new s21.cfg UA configuration file in order to register S21 with S22, using
uac -f config/s21.cfg
# optionally create a new s22.cfg UA configuration file in order to register S22 with S23, etc.

# then make a call as in (2)
