use ss7 controlled trunks to the PSTN when PRI no longer makes sense for technical, policy, or economic reasons when using F link SS7 linksets to control IMT, they function very similar to PRI trunks; when using A link linksets connected to STP, then you can have a single linkset or combined links

This idea has been batted around like a worn out cricket ball. It seems like a great idea but no one ever does it. Controlling AS5350 and other media gateways like it is usually done using MGCP. Open protocol - seems cool. Seems like something like Asterisk or ss7box could be the controller. In

if one slot out of 48 is for an SS7 link, then this configuration is called an 'F' link - it is a single link linkset if asking about T1 then chances are good that you are in an ANSI world - the ANSI world connects to the SS7 net via mated pair STPs - your node needs at least 2 dedicated T1 using

if you have Sangoma cards you can use ss7box; SAM is working; clustering working; it's a stable platform that runs ITU and ANSI; it's free, unrestricted, and copyable now; until distribution and documentation are set up to be autonomous, send me an email and I'll see that you get a copy and I'll he

are those 2 "hosts" STPs or SSPs? what you describe could be a combined linkset if connected to STPs and using ANSI SS7; if using ITU then this might be a primary/alternate linkset scenario; my experience says the combined linkset concept exists in ANSI SS7 and not in ITU On Thu, Jan 12, 2012 at 8

you are correct; the long-held suspicion is that the mgcp between the pw and mg has proprietary extensions; using wireshark to sniff the protocol would be the first step; would need cold start, warm start, and normal operations captures; normal ops would contain lot's of normal and abnormal call sc
