Hello,
we have a QSIG connexion between PABX Bosch and gateway 2821 with MGCP ,
gateways 2821 with H323 for the outside calls and CCM 4.2.1.
Phones Bosch ---- PABX Bosch --- QSIG link --- 2821 MGCP --- CCM --- 2821 H323 --- PSTN
It works perfect with Ip Cisco Phones
It works pretty good with Analog Bosch Phones.
But on fewer numbers destination (10% of all external calls) from Bosch Phones and exclusif phones Bosch,
we have got a disconnexion after 4 secondes.
We have got logs from 2 gateways.
The most signifiant information on two gateways is :
Oct 19 14:12:54.952: ISDN Se0/0/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x8051
Cause i = 0x80E6 - Recovery on timer expiry and "Cause i = 0x80F2 - Unknown cause value"
What is the solution ?
Thank You for your help.
Regards.
