VG202 integration H323

Hello All,


I have integrated VG202 with CME using H323. The integration is through IP connectivity.


I can make calls from IPphone registered to CME to the Analog phone connected to VG202.


I could not hear any dial-tone when the Analog phone goes off-hook nor I can dial any Cisco IP phone connected to CME.  I tried to connect to different port on VG202, used different Analog phone, reloaded the VG202. No luck.


Please find below the config of  VG202.

  • Hi, few questions:

    1. Can you make phone to phone call within VG phones only?

    2. Do you get incoming calls @CME when attempting from VG? Enable debug & trace.

    3. If yes, what's the disconnect cause you are getting into CME router?

    4. Try the same from CME to VG and check the trace & disconnect cause.

  • Hello Rahman,

    Thanks for your suggestion. Dialing out to CME registered IP Phones issue is resolved by adding ip address trusted list on the CME which was missing the config. But for the dial-tone issue, I have to remove all the unnecessary commands which were configured for SCCP integration by another Engineer and I do not know which removed command solved the issue :)

    Thanks,

    Viki
