IPO403 -> Definity -> GSM GW and echo problem

[d14v0l0]

Hello,

I have problem with echo.
Config:
IPO403 [3.2.17] --- trunk to Definity --> Definity ----- co trunk to gsm gateway---> GSM GW

When I call any ext on Definity I don't have echo.
When Any call from Definity to IPO's ext we don't have echo.
But I have echo when call mobile phones because call flow is:
ipo->Definity->gsm gw.

If I use same gsm gw on Definity I don't have echo.

Any idea

try setting the gsm gateway up to the ipo direct, and see if you get echo there.

play with echo cancellation options on all components.

I can't connect ipo and gsm gw because I don't have analong line port on ipo.
I already play echo cancellation on both devices.
How I say, when I using this trunk for communication between ipo and Definity ext I don't have echo.

Can I connect gsm gw via plain ext port to ipo todo same job?

i do not think a digital station port will work. the gateway may be able to accept other than analog station port though.

I mean to connect gsm gw on analog ext port, or on same way to reduce echo

i do not think a digital station, or analog station port will work. probably need a trunk port.

I don't have analog trunk port on ipo
