VOICE LAB - cannot reach calls from one site to another

cazuela31

Hello Everyone!!
I'm really newby on this so I hope maybe one of you experts guys could help me with this..
the topology is the following.. (also attached)
I'm running cucm7 on a vmware machine for one site (siteA) and cucm-e for another site (siteB), both sites are interconected.
On siteA I have an h.323 gateway (cisco 2600 router-running a voice capable IOS).
I've added in cucm7 the h.323 gateway, created the route group, the route list, and the route pattern pointing to siteB.
On the gateway I have the corresponding dial-peer pointing to siteA cucm7, and another poiting to SiteB cucm-e. Also SiteB cucm-e has one dial-peer pointing to h323 gw on SiteA.

My problem is that I cannot place calls from one site to another .. seems that the call it's being stucked in the h323 gateway.. but i'm not sure


here the configs of the h323 gw and cucm-e

btw, no routing problems..

You need to have dial-peers from CME to CUCM 7 to match. I don't see where it does from the site B. Look up site to site Call Managers and look at the voice gateway configs.

dtlokee

Are you trying to route them as VOIP calls from CUCM 7 to the CUCME router on net? Or are you trying to route them through the PSTN to the other site? If you are routing them on net you don't need to send them to the h323 gateway in your site A unless you intend to use it as a gatekeeper.

Luckycharms

Saying that you UCM configuration is correct.. You will need to do two things ...

Voip to Voip calls need to go through a cube...Second (don't have too but is always a good idea) address the inbound dial-peer situation on the CME router... so add the following commands..

H.323 GATEWAY
voice service voip
allow-connection h323 to h323
!
dial-peer voice 1 voip !don't have to do this but will fix DTMF problems later)
dtmf-relay rtp-nte
!
dial-peer voice 2 voip !don't have to do this but will fix DTMF problems later)
dtmf-relay rtp-nte
!


CUCM-E configs
!
dial-peer voice 1 voip
incoming called .
no codec g729r8 ! it will default to that...
!
