Hi,
Our network is as below
Soft-switch ---SIP--> SBC ---SIP---> ISR 4321 ---Q.931--> TDM PBX
We're sending CLEARMODE only codec from the SIP side to the ISR4321 and want it to transparently pass on the bearer-capability (i.e. unrestricted Digital) to the TDM PBX. However, the ISR is setting it to Speech in the SETUP message.
is there any way on the ISR to do it please?
