Hi,
I have configured a Cisco Call Manager setup to cater 150 IP Phones, with CCM 4.1.2 and Cisco VG 2821, we have E1 PRI for DID and 16 FXO Lines for Local Calls, when the call comes through the FXO, I get Unknown Number on the IP Phones. The below is the configuration of the Voice Port.
voice-port 0/0/0
supervisory disconnect dualtone mid-call
supervisory custom-cptone UAE-SIEMENS-SWITCH
supervisory dualtone-detect-params 1
input gain 14
compand-type a-law
timeouts call-disconnect 5
timeouts wait-release 5
caller-id enable
Thanks & Regards,
Sriharshaa Prabhakar

what did u use as a control protocol on VG 2821 (mgcp,h323,sip,...)?

MGCP

and this is the reason, since CallManager does not support caller ID on FXO
ports from MGCP gateways.
u should use h323 for this purpose
