Greg,
	Another user called in this morning with this problem. Luckily 
they had 2 lines, so I was able to do a little troubleshooting. The called 
looked normal. It showed V.34 and V.92. Connection speeds were 
26000/24000. I had the user disconnect and enter 'AT+MS=v90,0. They 
reconnected and this time it was a V.34 call and everything worked fine. 
So, does this mean that the problem is a V.92 problem? Any suggestions on 
how to maintain the V.92 calls and resolve the problem?

Thank You,
John McKinney
