: Hi all, I'm working on a research paper on how
: voicemail systems are integrated into
: cellular providers. I currently understand
: that in both GSM and CDMA systems there is a
: MSC which is the Mobile Switching Center.
: From what I understand so far, voicemail
: systems are a sub-module attached to the
: MSC. Hopefully I understand this correctly
: so far. It's from this point I'm having
: difficulty understanding the integration.
: One site stated that, "The voicemail
: system connects to the MSCís in a GSM
: network by way of voice trunks and SS7
: signaling links". So, going by way of
: that statement I believe the voicemail
: system is basically making a call using the
: ss7 protocol to the voicemail system.
: I would love any corrections to my
: understand as well as any links, graphics or
: anything else you could help me with.
: Greatly appreciated,
: Paul Jack
