Hi Prabahar, On the call from CME, GK finds that the priority 10 trunk is already max out and tries the priority 9 trunk (pub) to make the call. ----I found that the call still goes thru H323-ID: CCM2CME_2 , even though there was one active call on H323-ID: CCM2CME_2 , the second call from CME to HQ still uses H323-ID: CCM2CME_2 somehow and it did not use H323-ID: CCM2CME_1 curious to know if it was working OK with your setup ???? -AB

Regards, Prabahar . Only one call allowed from CCM to CME over GK . First call from CCM should use the subscriber . Second call from CCM should use PSTN if already a call on subscriber . While a call on subscriber, a call from CME should use publisher . Don't use bandwidth CLI on GK Solution is to use "endpoint max-calls" CLI on the GK, it requires following two additional CLI's endpoint resource-threshold arq reject-resource-low Also set the CCM parameters to "False", Stop Routing on Unallocated Number Flag Stop Routing on User Busy Flag Have a RL in CCM to use GK as primary and 6608 as backup. It works like, . On the first call from CCM, no issues . On the 2nd calls from CCM, try to placed on the subscriber trunk and get rejected due to max-calls and will NOT try publisher (as for as CCM, only one trunk is between GK and CCM. It will not consider CCM2CME_1 (publisher) as second trunk). Calls will fail over to 6608. . On the call from CME, GK finds that the priority 10 trunk is already max out and tries the priority 9 trunk (pub) to make the call. . Any number of calls can be placed from CME to CCM over publisher trunk. Can be restricted using "endpoint max-calls" CLI on CME.
