Inevitable redundancies Have to cover related topics, to provide context, for easy comprehensionSome overlap between “Call routing” and “ISDN config”, again, to provide proper contextConversely, if you find an area/topic is not covered, it is probably not within our scope
Two approaches possible-Problem/symptoms driven approachTutorial relevant topics approachWe will mostly do tutorial approach, but will discuss some problems/symptoms, as case studies
With MGCP, CUCM can decode Qsig facility IE. Calling name and redirect number, which are carried in the facility IE, are therefore available only when using MGCP trunks. You might need this function for voice-mail access
ANI not provided in T1 CASFGB.
Dial-peer no different from regular PRI, only pointing to ports with primary and backup D channels?
R2-Analog- defined in ITU-U Q.411 and is typically used in carrier systems. Signaling uses a Tone/A bit.R2-pulse - n ITU-U Supplement 7. It is a variant of R2-Analog in which the Tone/A bit is pulsed rather than continuous and is typically used for satellite links.
The router responds to the setup message with a SETUP ACK. This informs the network that it is ready to receive further information messages containing additional call routing elements.
