Transfer Capability and h.323 trunk trouble

Unanswered Question
Mar 21st, 2008

Hello all!!!

I have 2 CCME. Only one have ISDN PRI connection to PSTN. Locally registred ip phone can succesfully make a PSTN call.

The debug isdn q931 is:

Bearer Capability i = 0x9090A3

Standard = CCITT

Transfer Capability = 3.1kHz Audio

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

I have configured second CCME to have h.323 trunk to first CCME. Now ip phone that registred on second CCME can make calls to PSTN, but not to all destinations.

The problem is an anknown call type:

Bearer Capability i = 0x8890

Standard = CCITT

Transfer Capability = Unrestricted Digital

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

Transfer Capability = Unrestricted Digital

I need that calls from second CM to PSTN have Transfer Capability = 3.1kHz Audio or Speach

Can I configure this?

CCME1:

controller E1 0/0/0

pri-group timeslots 1-28

interface Serial0/0/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

isdn sending-complete

Try with unique destination pattern for each CME and also paste the sh run, sh isdn status, sh CCAPI inout.
