Inbound calls Making an Outbound call

Got a weird one here. I have VOIP.MS for service and I have an Inbound Route setup for a DID pointed at a ring group, and others are pointed at Speaking clock, conferences, etc. I have had alot of complaints and I have witnessed it myself that when I make an Inbound call, there are times that all works fine, but other times that I see the Inbound, then and Outbound, Another Inbound, Another Outbound (Like a Loop) and these calls fail to congestion 503. Has anyone else has this type of problem?

Logs are the only way we could possibly troubleshoot this one. /var/log/asterisk/full.
