I think there is one benefit *when the caller dialed a wrong number!*
If overlap signallig were used, the caller might be informed by the proxy immediately. In en bloc signalling, however, the caller will only be altered after he dialed the complete wrong number watsting time and resources. ------------------ Original ------------------ From: "Brett Tate"<[email protected]>; Date: Tue, Jul 16, 2013 01:19 AM To: "SIP Learner"<[email protected]>; "sip-implementors"<[email protected]>; Subject: RE: [Sip-implementors] Overlap signaling in a native SIP network > In PSTN networks, it's beneficial to try to establish > a connection between the caller and the callee before > the full phone number digits are collected.

I'm not aware of any benefit; however RFC 3261 defined 484 to allow for it. RFC 3398 and RFC 3578 discuss the ISUP conversion. . _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
