[OpenSBC] OpenSBC Does Not Reply To Metaswitch reINVITEs

[Erik B. <eri...@ma...>]

Hello again,


    After realizing what the problem was with my SBC dropping the audio after 20 seconds, I've come upon a new interesting issue.  Once again, calling into the UA is fine and the call lasts forever, but when calling out from the UA, sometimes the call ends after 1 minute 5 seconds.  The reason for this is known: the Metaswitch is sending out reINVITEs to the SBC but the SBC fails to acknowledge them.  The strange thing is that this does not happen all the time.  So far, the only discernable pattern I've been able to see is between calls that would be long distance (an added 1 to the 10 digit number) versus local calls.  It would appear that any time the UA calls out to a long distance number the SBC does not reply to the Metaswitch's reINVITES.


Any thoughts on why this would be?


 Thanks in advance,


Erik
