Troubleshooting disconnect cause 0x64 on ISDN calls to PBX

Hi!

Does anyone know how to troubleshoot a disconnect cause 0x64? (invalid information element contents)

It?s an AS5350 connected to a NEC NEAX 2400 PBX.

The problems is with calls outboud through the E1 ISDN to the PBX.

I already tried setting "bearer-cap" to both Speech and 3100hz with no results.

Anything else to attempt?

Regards,

Ariel

Please post the complete call setup and teardown as seen with "debug isdn q931" and "term mon".

The PBX may not like the calling/called numbers or type/plan, but is throwing an inappropriate error code.
