Trunk path optimization

[jneiberger]

I don't know what Avaya calls this feature, but Nortel has a feature called trunk route optimization that it uses in conjunction with another feature called trunk antitromboning. It uses these features to avoid unnecessary call paths. I'm wondering if DCS has something similar because we're running into a problem between two Avaya systems.

Forget the specific problem we're having for now. I just want to ask a hypothetical question. Let's say you have PBX A and PBX B. Someone connected to PBX A calls someone on PBX B. That uses up one call path. The recipient of the call transfers the call to a person hanging off of PBX A. Does DCS have a feature that will prune that unnecessary path through PBX B? At that point, the call resides completely on PBX A, so it would be helpful to prune that path. That's especially true if voicemail is involved and the call ends up being transferred again.

I'm hearing conflicting information, but the techs for the VAR we work with think that DCS won't prune those unnecessary paths.

Is that true?

Thanks,
John

John,

Unfortunately your VAR is correct. You would tie up two trunk ports with your scenario. We run into this quite a bit because of a centralized voicemail system and multiple PBX systems using DCS together.

That actually helps a lot. We're having this issue with our first set of IP trunks and we thought it was a problem with the trunks. We apparently just have not noticed this on our other trunks because of the number of calls on them. If there's always a bunch of active calls, you're not going to notice if one or two extra are busy that don't really need to be.

I wonder why they haven't fixed that? Nortel doesn't have this issue. I'm surprised Avaya didn't bother to fix it.

Look at DCS with Re-Route or QSIG with Re-Route. Both are capable of eliminating the trombone effect.

How do you turn on re-route with DCS?
