We are running version Version AR4.00 ML031.00 and I have been experiencing a strange trunk selection problem on outbound calls. I am wondering if anyone has seen this before and knows a solution.

We have 2 PRIs that are 2 way and regardless of inbound or outbound calls they are configured to route in reverse order starting at channel 23 and going up (22, 21, 20 etc). When that circuit is all busy it should hunt to channel 46 and route backwards through the second PRI.

That all seems to work fine with one exception...randomly channel 46 will get tagged for an outbound call bypassing whatever channels are open on the first PRI. It is always on Outbound calls so I think I can narrow it down to something in the PBX. I have watched it happen and cannot find any patterns and even have duplicated the problem myself by sheer luck. We have never filled that first PRI to my knowledge so calls should, in theory, never have hit that second PRI.

It is not based upon a particular trunk because it does not always happen when X number of trunks are busy or anything like that. We can have 1 active call or 10. It does not happen to just certain extension, it seems to happen to anyone and it only occurs 4-5 times a day. I cannot find any patterns so far.

Anyone ever seen something like this and have a suggestion for me to check? Thanks a bunch.
