Hi All,


We are using CCM 4.1 and GK 12.3, We have 4 GK's running in clustering mode and we have 24 CCM sites. All are working fine however now we have a challange in place we want to setup CS1000 in 6 new locations,


Existing Setup : One GK is acting as Primary GK for 6 Call Managers and secondary for 6 call Managers.


we have tested few things.




1) Point to Point(LAN) communications between CCM and Nortel CS 1000, everything works fine, though we had few challanges.


2) We have registered CS 1000 to the GK now the calls are not maturing, probably we are not understanding how to route the calls to Nortel.


Scenario 2(a) When we call from Cisco to Nortel we see the digits which are supposed to come at GK, they come fine however we are getting the below error message..


Jan 23 16:25:08: gk_rassrv_arq: arqp=0x62239c58, crv=0xA14, answerCall=0

Jan 23 16:25:08: gk_dns_query: No Name Servers

Jan 23 16:25:08: rassrv_get_addeinfo: (100079111) Tech-prefix match failed


Jan 23 16:25:08: rassrv_get_addeinfo: (100079111) Matched zone prefix 10007 and remainder 9111

Jan 23 16:25:08: rassrv_get_addeinfo: (100079111) default-tech gateway selection failed, status = 0x805

Jan 23 16:25:08: rassrv_get_addeinfo: (100079111) unknown address and no default technology defined.

Jan 23 16:25:08: gk_rassrv_sep_arq: rassrv_get_arrdinfo() failed (return code = 0x103)


From the traces it is understandable that its not matching the tech prefix and GK is not able to map the call to the prefix found.


We have default tech prefix 1#* for different call managers and i havent given any other tech prefix for nortel.


I have tried to register Nortel using tech prefix 2#* as well and giving the ip address of nortel something like


gw-type-prefix 2#* gw ipaddr XX.XX.XX.XX 1720, and on the CCM have tried to prefix 2# before the dialing string on route pattern level but the digits what i see on GK doesnt show 2#, and we gets the same error.


What do i need to do? i cant paste the configs of the GK as its too senstive to be shown here, i am just putting an example of Callmanager config on GK and Nortel as well.



########################


CCM Site configs on GK.


zone local SiteA "domain name"


zone cluster local SiteC siteA

element SiteB "ip address" 1719


Site C is name of Cluster, Site A is for Primary CallManager, Site B is backup.


zone prefix SiteA 10000*

gw-type-prefix 1#* default-technology


#########################


For Nortel Below is the config.


zone local nortel_ss "domain name"


zone cluster local nortel_C nortel_ss

element nortel_B "ipaddress" 1719


zone prefix nortel_ss 417000*




Suspect points to the configuration, where i think we are doing something wrong. Please suggest the way to take solve of this.


Will really appreciate.


Thanks,


Daljeet
