Outside/Inside calls route differently

[soasol]

I have a G3R with R11.

Whenever I call a certain trunk from the PSTN I am routed to the 2nd DS1 in the group, whereas when I dial from inside I am routed to the first DS1 in the trunk group.

Any ideas as to why dialing the same trunk would make an outside call skip an entire ds1.

I have not tested in a while, but I believe if I busy out the 2nd DS1, outside calls will not go to the 1st. Like the first doesn't exist.

On the first page of your trunk group form for your PRI group their is a setting that routes calls like you are describing. The choices are
1. Cyclical
2. Ascend
3. Descend

It sounds like your group is set for cyclical. This would route incoming and outgoing calls at different ends of your group.

After reading my post again, I realized that I didn't explain it all that well. Sorry about that.

These are all incoming calls to the same number that route to the same trunk group.

Let's say I call x90000 from my cell phone, it will route to the 2nd ds1.

If I call x90000 from my desk phone it will route to the 1st ds1.

Why the difference when it gets there the same way?

Thanks.

Are these 2 ds1's acting like a single pipe?
If so this is probably the way you want it.
if it is a single trunk group you want the inside to go from 1 down and the outside to go from 48 up.

If this is not the case, you will have to provide more info on your configuration.

Are these trunks AT&T SDN? If so, they may have it configured so that "on-network" calls hit the first trunk group for inbound.

If I understand what you are saying whenever you use your cell phone to call one of your DID's, the cell phone is a different provider, and comes in on the 2nd DS1, however when you are "on-network" and place a call to the same "network" (for lack of a better word...) the call comes in on the first DS1. They probably have them configured as 2 different trunk groups, but have shared traffic between them, and will overflow to each other.

I've seen this before and there are a multituded of reasons that it may have been set up like this.

It's actually a trunk to a conferencing system. We have the DID extension routed to a single trunk group with two DS1's. We are using aar to the route pattern which has the trunk group in it.

So dial x1234 when on network or call 999-999-1234 from a cell and get to the same route pattern.

The trunk is a tie. DS1's are TN767E and TN767D. Both robbed bit b8zs esf.


Thanks!
