SIP protocol issue ? missing first seconds of MCP treatment

[GregorV]

When a call arrives on SIP-Server and a treatment is started, then the first seconds are cut off. We have seen a [b]reinvite[/b] from outside after there was the [b]established[/b] from MCP. So the audiofile is started while there are new negitiations for the connection while the caller hears nothing. We have two possibilities to send a call to SIP-Server. A direkt dial from an external number: no issue BUT if the call comes from a network SIP-Server via servicenumber then we see the issue. A workaround is to play 100ms silence before starting the regular treatment. Is this problem known and is there a 'cleaner' solution ?

You may try to set reuse-sdp-on-reinvite to "true" on the msml trunk to check if that helps.
