For local calls we are routing out through a commercial VEGA voicestream pots unit to an adtran channel bank and then from there to our class 5 soft switch.   The sip to sip calls and the long distance calls work great.  The problem is with the local calls going out the pstn gateway (vega to channel bank to soft switch).  When I dial a local call from one of my ATA186 units, I hear a sound that is like someone pressing down a digit on the phone key pad and temporary dialtone.  After about 1 second of this, the call proceeds & terminates normally.  Below is part of what comes up in the sip debug log :
