We have two issues here: 1. Invite is being sent only 4 times, while according to the RFC we need to send 7 for total timeout of 64 x T1. We should really follow the RFP. 2. Indeed T1 should be set as an estimate of network latency, but an estimate of 100msec for a RT on WAN in general (which may include international locations) and mobile network in particular is too low, and should be at least doubled (providing that we fix item 1, otherwise we my need a higher number for T1, because it takes mobile networks several seconds to establish a data channel following issuance of the first invite). Ideally T1 should be a parameter, which would be adjusted to strike a balance between or reliably reaching users, and need for acceptable timeout for redundant configurations. This balance depends on application, topology, and other specifics. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
