bcm50 to netcentrex

[relicks]

hi to all
we are trying connecting bcm 50 to netcentrex network with an ip trunk. i think everything is ok, because when i use softphone i2050 to call a phone that connected to netcentrez,phone is ringing and i can get conversation.
but when i use digital, analog or iphone there is a problem.
the test resuslts are belove.

Softphone: We can call. It rings. We can answer. Call establishes. We can conversation. Voice quality is good.
I2002 : We call. Netcentrex side rings for one second. We get ring back. We can see the caller at the display of Netcentrex IP phone that is i2002. Before we answer call drops.
T7316 digital telephone: We call. Netcentrex side rings until we answer. We can not get ring back. When we answer, call drops in 3 seconds. During those 3 seconds, we can not get conversation. Call does not establish.
Analogue telephone: We call. Netcentrex side rings until we answer. When we answer, call drops. Call does not establish. No conversation.

any idea??

relicks, would you explain a little more about the Netcentrex network? I'm not familiar with it, so would like to hear more detail about that side of the call.

I'm thinking it might be a codec issue but I'm not too experienced with it to say for sure. I thought if you could explain the Netcentrex portion maybe it would help.

I would agree with BCM programmer it sounds like a codec issue or modulation error. Have you tried monitoring the BCM with BCM Monitor and watch and see what the IP devices are doing.

Also if you logon to the BCM and check what the preferred codec is for the IP phones and IP trunks and try setting them the same and see if that fixes your problem.
