CCME/CUE AA Intra-Site Transfer Issue

Greetings All,

We have CUE 2.3 and CCME 4.0 running on IOS 12.4(9)T. This is a two-site distributed network, with CUE & CCME co-resident on a 2800 series ISR at each site.

We are trying to set our system up so that callers that reach CUE AA can enter an extension number for a user at either site and have the AA transfer the call appropriately.

For example, caller dials the PSTN and reaches the AA at Site A and enters an extension or does a dial-by-name for a user at Site B. We would like for the call to be transferred to Site B.

We are able to make on-net VoIP calls from Site A to Site B and from Site B to Site A. Calls are successful either when the extension owner answers the call or if the call goes to voice mail. Works fine either way.

Our WAN dial-peers use the G729A codec and we have DSP resources configured to do transcoding. All this seems to work fine for calls that are transferred by a person, but does not work when the call is transferred by the AA.

We have transfer-system full-consult set up under telephony services on both ends.

We also have voice mail networking set up and it is possible to dial the voice mail pilot number at one site and leave a message for a user at another site.

In addition to setting up network locations in CUE, we have also set up remote usernames in CUE at each end for users at the other site.

When we try to use the AA to transfer calls to the other site, the AA attempts to do the transfer, but the call goes dead after a couple of seconds.

If anyone has suggestions or could point me to documentation that covers this type of scenario, I would be grateful.

Thanks,

John

Have you setup voip hairpinning to allow h323 to sip and sip to h323 connections on both routers ?

Also can you paste your router configs.

When you say call goes dead after a couple of seconds, does it disconnect or just silence ?

Thanks for the reply.

Yes, we have the following configured at both ends:

voice service voip

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

Here is the PSTN caller's experience:

1. Dial PSTN number that is PLAR'd to the AA

2. AA answers...press 1 to dial by extension 3. Enter extension 3812 (which is at Site B)

4. AA announces "calling 3812" then a click, then disonnect.

I'll gather up our configs and post them shortly.

Thanks again,

John

Just an update for those interested.

Setting transfer mode to blind bye-also in the CUE sip subsystem did the trick:

ccn subsystem sip

gateway address "10.6.6.1"

transfer-mode blind bye-also

end subsystem
