calls from UK PSTN to CUE fails

[Chris Drew]

I am getting disconnected when i forward calls from the pstn to CUE. Works fine internally but from the PSTN the call fails. I think this may be a trasncoding issue as the CUE can only talk g711ulaw but i am not sure where or how to verify this My CUE is in the same device as the PSTN GW a E1 PRI. TIA

Yosh,

I set the codec to G711 to the incoming dial-peer but even the calls were not working, so I removed it.

I will give it a try with all the changes you proposed and let you know.

Regards,

The cause value = 47 indicates a "resource unavailable" event.

Can you please provide the CUE configuration?

What is the your voice mail box pilot number? In your dial peer you have mentioned,91 as VM pilot number but on your phone you are forwarding the call to a different VM number instead of 91.

Thanks

Hello,

The voice pilot number is 91. Where do you find that the call is being forwarded to a different VM of 91?

Thanks,

Reg.

Hello,

Can you please share CUE configuration?

 call-forward busy 3199 (Voice mailbox pilot number)
 call-forward noan 3199 timeout 20

What is 3199?

Thanks

Hello inderpreetsingh23,

find the CUE config attached.

I also thought of the "AllowTransferExternal" option in the GUI CUE. Is that a possible cause? (find also attached the screenshot).

Thanks,

Reg.

I don't think allow external transfers is causing any problem. Just change it to true and then try. Reload your CUE module and then test the call again.

Please configure the following:

voice service voip

sip

bind all source-interface <ip address of interface>

[CSCO12205445]

Sorry, what ip address of interface? CUE? Voice LAN? ...?

Thanks,

Reg.

Voice vlan.

Going through the debugs I think your call is failing due to codec mismatch.

Try this config:

voice class codec 2

codec preference 1 g711ulaw

codec preference 2 g729r8

dial-peer voice 91 voip
 description Unity Express Voice Mailbox pilot number
 destination-pattern 91
 session protocol sipv2
 session target ipv4:A.B.C.D !!--> IP@ ISM0/0 CUE
 dtmf-relay sip-notify
 voice class codec 2
 no vad

Oh sorry, I beg your pardon. That was an example, not the config I am using.

The config for the CME and debugs are above attached too.

Thanks,

Reg.

I think it's still a codec issue. You can call internally fine because the codec hasn't been decided yet. Likely when you call from the PSTN the codec has been decided on, and CUE doesn't like that codec, and a transcoder isn't available to help.
