Need to know what kind of firm this number belongs to

I got a call from this number late yesterday afternoon.  A gentleman named "Ernie"  left a voice mail and told me that I needed to call this number, his personal cell number, to verify some information before it went to the clerk's office.  It is coming out of Orange County, California, so I"m assuming that it is some sort of scam or a collection agency trying to scare people about being served papers or some such tactics.  I'm not going to call him back.

This was a phycho collector and he threatened me...

I got the call.....My ex apparently was involved in a civil law suit due to charges on a credit card, leading to theft, larceny, breach of contract, blah blah.  He apparently had this card while we were married, I was listed as an authorized user, and also involved in said law suit as my State is community of property.  He was thankful that I responded to the voicemail and due to my sincerity he would delay the summons which was scheduled to take place at my work today.  He then mentioned that if I wanted to be removed from this law suit, I would have to have my ex remove me or I could pay my 50% portion and automatically be removed.  When I said that I would need something in writing and would he please repeat his firms name, he got short and said he had already told me that information and it seems I would prefer to be served.  I told him I'd call back and hung up.  I will not be calling back.  It all seemed very real as my ex had got himself in financial trouble, so very easy for someone to get scammed!!!!

Funny...this just happened to my husband today...same exact wording as the one above. Wanted the money today or he was calling the courts for a summons!! Nice! Now we will have to change the number.
