Siemens Switch EWSD signaling problem with AS5300

[daeakins]

I have an AS5300 which I am trying to connect to a Siemens EWSD switch using ISDN PRI. The controller comes up. When I do show isdn status everything looks good. But when we try to place a call some of the digits are missing and I get an error message of Invaild information element contents.

Please find the attachment of the debug I ran:

Here is the config on the AS 5300

interface Serial0:23

no ip address

no logging event link-status

isdn switch-type primary-ni

isdn incoming-voice modem

no cdp enable

dial-peer voice 1 pots

incoming called-number .

direct-inward-dial

!

dial-peer voice 10 voip

destination-pattern 1..........

progress_ind setup enable 3

voice-class codec 99

session target ipv4:66.88.14.254

dtmf-relay h245-signal h245-alphanumeric

ip qos dscp cs5 media

!

I believe it is a D-channel problem on the switch end. Any suggestions? Thanks. I have searched Cisco's site to no avail.

Your configuration is OK from the ISDN perspective.

What I can see in the debugs&config is that the AS5300 is receiving a call to '3828345' for which there is no dial peer configured (no route!!) with an appropriate "destination-pattern".

The AS sends back the "Requested circuit/channel not available" cause code for disconnect.

You can add a dial-peer pointing to a correct destination (voip or pots) configured with "destination-pattern 3......" for example.

You can check if the router is able to handle a specific destination by using:

CCM-EXPRESS#sh dialplan number 002233755

Macro Exp.: 002233755

No match, result=1

CCM-EXPRESS#sh dialplan number 60

Macro Exp.: 60

VoiceEncapPeer10

peer type = voice, information type = voice,

description = `',

tag = 10, destination-pattern = `60',

answer-address = `', preference=0,

output missing

I try to work around with my as5800 the following call flow :

customer---->telco house---->as5800------>Telco house

<232....> <160221>

This I want to do by sharing same E1 PRI for both inbound and outbound dial-peer.The config I did for dial-peer is :

translation-rule 1

rule 0 2055 160221

dial-peer voice 2171 pots

incoming called number 217232....

dial-peer voice 2172 pots

destination-pattern 2055

translate-outgoing called 1

port 1/0/2:d

I dont have any voice feature card in as5800 and presently it used for only internet dial up access and no voice application.

The information I got from cisco site is :

"call hairpinning without the need of a Voice Feature Card (and its digital signal processor) is available only on the Cisco AS5800"

Till now no success for me.

Pls help.

thanks and regds,

Prasanna

Thanks, I knew that the dial pattern wasn't correct. I was waiting for the carrier to fix it on his side. But I have never seen it come across with the modem error message. I have seen it come across with no matching dial-peer. As soon as the carrier fixed it on his side it worked beautifully. Thanks very much
