the following scenario, it seems that ser may not be sending the BYE
to<BR>the right port on the cisco, is that possible? The cisco is not
registered<BR>with ser, it is a trusted IP. The DID is an alias for my
softphone UID. This <BR>only happens for pstn-voip calls, when calling
voip-pstn, ser always talks<BR>to the cisco on port 5060 and the BYE is
obeyed, whichever end sends it<BR>first.<BR><BR><BR>call

BYE<BR>ser:5060 ->

OK<BR>ser:5060 ->
cisco:51339 BYE<BR><BR>So the cisco has used 3 different ports
during this call, one for the<BR>INVITE, which ser then uses to send replies
back to, but the ACK comes from <BR>a new port, and then the eventual BYE
comes from a 3rd port.<BR><BR>I can understand how the cisco tries not to be
stateful and uses different<BR>ports for each message, but how is ser
supposed to communicate back to it if <BR>not on the port used by the
original INVITE? Perhaps it should only talk to<BR>the cisco on port 5060?
If so how do I make it do that? Is the cisco<BR>misbehaving by using many
different ports when it originates the sip call? <BR>Is that a known IOS bug
perhaps?<BR><BR>Help and wisdom
