Hi, dear all!
I have a simple scheme: GW--h323--CUCM--CCX, there is a CTI Route Point with an IVR application. When calls are placed from PSTN or from internal extensions there is a random delay with some ringbacks (0 to 15 seconds), played by (?) IPCCX, after which the IVR scipt starts.
I checked CPU load, ip reachability between CUCM and CUCX, all is correct. What it may be?
