UC520 CUE sending busy signal on pilot number

Answered Question
Sep 23rd, 2008

Hello,

I tried to set up the CUE functionality on the 520 series router. There is apropriate interface for the CUE:

interface Integrated-Service-Engine0/0

ip unnumbered Loopback0

ip nat inside

ip virtual-reassembly

service-module ip address 10.1.10.1 255.255.255.252

service-module ip default-gateway 10.1.10.2

there is static route:

ip route 10.1.10.1 255.255.255.255 Integrated-Service-Engine0/0

dial peer with the pilot number:

dial-peer voice 4000 voip

destination-pattern 4000

session protocol sipv2

session target ipv4:10.1.10.1

codec g711alaw

no vad

MWI on/off:

ephone-dn 3

number 8001...

mwi off/on

telephony-service

voicemail 4000

voice service voip

allow-connections h323-sip

then I logged to CUE with:

service-module integrated-Service-Engine 0/0 session

There I have:

ccn trigger sip phonenumber 4000

application "voicemail"

enabled

maxsessions 4

end trigger

username gpilat create

username gpilat phonenumber "201"

voicemail mailbox owner gpilat

and then forwarded on CME my 201 phone to 4000 (cue pilot number).

However I am getting busy signal. I tried to do some debugging but with no luck. SIP messages look OK between CME and CUE. Seems I am doing sth. wrong.

Please help,

best regards,

Goran Pilat

I have this problem too.

Hi Goran,

Please include the following under the dial peer:

dtmf-relay sip-notify

codec g711ulaw

See what happens when you dial 4000

Hi Goran, when you dial 4000 from an IP phone what do you get? Can you access CUE? If not go to the web interface of the CUE and run the initial configuration.Then you have to synchronise the CCME and CUE configuration. The configuration you have posted above looks OK.

Hi Chandrasen!

Thanks for the fast answer. When I call 4000 from the IP phone, I also get busy signal. I did the initial configuration before and when I try to sync it says there is nothing found to sync.

Ideas? anything significant to trace?

thanks,

goran

Do you mind posting the output of the following debugs while placing the test call:

1. debug voip ccapi inout

2. debug ccsip messages

Regards,

Michael.

Hi!

Thanks a lot, that was it. I had to change the codec to ulaw.

Thanks again and regards

Hi!

I tried to integrate CUE/CME into provider's IP network whose softswitch supports only A-law. So now I cannot reach voicemail from the PSTN numbers (voicemail from IP phones works fine). Is it possible to change CUE from u-law to A-law? I also read that CME should switch between these two codecs with no further config, but this doesn't happen, CUE is unreachable.

best regards,
