[cisco-voip] ccm behind fw settings for routıng international calls to ISP

[gokhan senol]

Hi 
i use ccm 4.1.3 in LAN. But also i made an aggrement with an isp so that i will use their backbone for international calls.
CCM is behind a FW.
what should i do on FW and CCM for route my international calls to the isp
1.....do  i have to use static nat for ccm or if i use PAT will it be enough.  They asked me whether with an ID or with an IP would i send my CCM calls.
2.... isp says they will use h323. So i will add  isp 's gateway  as h323 gateway and which ports should i open from firewall.



thanks every1
