Re: [SR-Users] Dialog module's keep-alive feature uses wrong CSeq?

Hello, the keepalive is done via sort of a trick which needs to detect:   - if one side is no longer connected to the network -- keepalive results in retransmission timeout   - if one side is no longer knowing the dialog - so call-id, to-tag and from-tag values do not match -- keepalive results
