Multiple CMEs

Hello everyone,

I have three sites each running CME.

I want to allow each site to dial to the other.

There are firewalls at each site, but I have allowed RTP and other voice-related protocols and signaling between the sites.

When I try to call, I get busy tones.

I get a disconnect cause=38 which tells nothing much more than a network fault but I'm not sure exactly what's the fault.

I tried different codecs but still no luck.

Following are the dial-peers applied:

!

voice service voip

h323

no h225 timeout keepalive

call start slow

!

SITE-A Configuration: (Extension range: 7XX and 8XX)

!

dial-peer voice 6661 voip

description <<TO SITE-B>>

destination-pattern [12]..

session target ipv4:10.10.5.1

progress_ind setup enable 3

codec g711ulaw

!

!

dial-peer voice 6662 voip

description <<TO SITE-C>>

destination-pattern 3..

session target ipv4:10.10.4.1

!

SITE-B Configuration: (Ext. Range: 1XX and 2XX)

!

dial-peer voice 6661 voip

destination-pattern [12]..

incoming called-number [78]..

session target ipv4:10.10.5.1

progress_ind setup enable 3

Any ideas?

Thanks,

Re: Multiple CMEs

Configure a VPN between CMEs.

VoIP requires full, unrestricted connectivity.

Re: Multiple CMEs

If VPN is not an option at this point. These CMEs are connected through an MPLS network.

Any ideas?

Thanks,

Ahmed

Re: Multiple CMEs

Your FWs are not permitting full, transparent, any-to-any connectivity, so have fix or remove them.
