Howdy,

Is it possible to send calls from a Cisco Phone to CCM then out to a cisco gateway (2800) then across to another cisco gateway (2800) and back into Call Manager?


I've tried everything but Call Manager wont accept the inbound call unless it comes in from outside the gateway on a pots dial-peer first.


Call Manager ver - 6.1.2


Any ideas?

i guess u use voip dial-peer to voip dial-peer

in this case if u use h323 dial-peers

try to add the following command


voice service voip

allow connection h323 to h323


this way mostly will work


good luck

hope this helpful
