Hi All,
We recently had some E1 PRI issues and our Service Provider has asked us to set B Channel ID information to Preferred.
We are using a MGCP Gateway with CUCM 9.1.2
When we enable ISDN debug we could see the Channel ID as Exclusive.
Jul 25 13:02:07.566: ISDN Se0/0/0:15 Q931: TX -> SETUP pd = 8 callref = 0x0043
Sending Complete
Bearer Capability i = 0x8090A3
Standard = CCITT
Transfer Capability = Speech
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA98381
Exclusive, Channel 1
I tried to change it to Preferred by configuring the command, "isdn negotiate-bchan" under the serial interface but still debug shows it as Exclusive only.
Let me know whether we can change the B Channel information either in CUCM or MGCP Gateway.
