E1 with CAS trunks trouble

[cuecuito]

Hi,

I need someone’s help or support. I have configured E1 by CAS trunks through DTMF (DIUN2 Card). COT & COT are well defined but adding NTON parameter in order to avoid hearing next hop PBX tones.

However, long periods when calling are noticed if several hops are given until final destination.

How can I reduce those long periods between PBX hops?? Do I change any COS or COT parameters? Is it given at PTIME AMO??

I appreciatte your attention
Regards

I don't think there is any possibility to reduce time between PBX hops.
If a call forwarding unconditional is set from source to destination (over several hops) the calling is noticed in the same long time as in normal calling case ?
