We have problem as Existing Network

SCCP Phone <-->CUCM Cluster<---> H323 Centrer GW <----> H323 GW. FXS<---> Analog Phone.

I try to Route number to H323 GW at center and On H323 GW Center will have route to next H323 GW .

As i check during call from SCCP Phone it look like it try to connect to the Last FXS Port but It cannot

On SCCP Phone it wait long time till it give busy tone.

I already configure



voice service voip

allow-connections h323 to h323


no h225 timeout keepalive


AS it have dial peer on H323 GW Center point to H323 GW with FXS.


What Should i check why it cannot connect ?

Is H323 GW FXS act as CME or is configured in CCM ?

did you configure POTS dial peer in H323 GW FXS router which need to point to FXS port and VOIP dial peer to reach SCCP phone .

How H323 GW and H323 GW with FXS routers connected ?
