PBX Ericsson PRI TO PBX Alcatel PRI through 2 gateway Cisco

HELLO EVERYBODY.

I need to implement the calls from PBX Ericsson to PBX Alcatel through 2 Gateways.

When I call from PBX Alcatel to PBX Ericsson the call works fine, but from PBX Ericsson to PBX Alcatel to call seems completed but finally it gives an error:

"Cause i = 0x80E6 - Recovery on timer expiry" on gateway Cisco 3640 near to PBX Alcatel.

I have the following scenario:

On one side there is a PBX Ericcson with PRI card connected to PRI card on gateway Cisco 3825. On the other side there is PBX Alcatel with PRI card connected to PRI card on gateway cisco 3640, the sides are connected by WAN Link.

Here is a capture of the call on the gateway connected to the PBX Alcatel

c3640#

*May 6 13:20:44.715: ISDN Se0/0:15 Q931: TX -> SETUP pd = 8 callref = 0x09D4

Sending Complete

Bearer Capability i = 0x8090A3

Standard = CCITT

Transfer Capability = Speech

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

Channel ID i = 0xA9839F

Exclusive, Channel 31

Progress Ind i = 0x8183 - Origination address is non-ISDN

Calling Party Number i = 0x0181, '1051' Ericsson

Plan:ISDN, Type:Unknown

Called Party Number i = 0x81, '1000' Alcatel

Plan:ISDN, Type:Unknown

*May 6 13:20:44.751: ISDN Se0/0:15 Q931: RX <- CALL_PROC pd = 8 callref = 0x89D4

Channel ID i = 0xA9839F

Exclusive, Channel 31

*May 6 13:20:44.755: ISDN Se0/0:15 Q931: RX <- ALERTING pd = 8 callref = 0x89D4

Progress Ind i = 0x8188 - In-band info or appropriate now available

*May 6 13:20:59.611: ISDN Se0/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x09D4

Cause i = 0x80E6 - Recovery on timer expiry

*May 6 13:20:59.651: ISDN Se0/0:15 Q931: RX <- RELEASE pd = 8 callref = 0x89D4

Cause i = 0x8190 - Normal call clearing

I already increased the timer T310=60.000 seconds but I still have the same problem.

The date of the capture was May but I still have the same problem.

ANY HELP WILL BE APRECIATED

Re: PBX Ericsson PRI TO PBX Alcatel PRI through 2 gateway Cisco

Hi Walter,

Based on the debugs, when 1051 calls 1000.

All first messages are correct, incoming SETUP

PROCEEDING ALERTING then after 15 seconds Ericsson sends DISCONNECT, the phone actually rings?

If you answer the call what happens?

not sure if we are matching correct dial-peers, but somehow call is proceeding.

Let us know.

Re: PBX Ericsson PRI TO PBX Alcatel PRI through 2 gateway Cisco

Hi,

Can you post your configs and any corresponding dial-peers?

Can you also post a debug from a successful call?

Hi Gogasca thanks for answering.

Yes the phones rings but you can not hear anything on both sides.

Besides I see the calling party number.

Re: PBX Ericsson PRI TO PBX Alcatel PRI through 2 gateway Cisco

What version of IOS are you running on the 2 gateways? Does it happen all the time, or can you clear it by rebooting the gateway/s?

Re: PBX Ericsson PRI TO PBX Alcatel PRI through 2 gateway Cisco

Hi,

Do you have the "voice rtp send-recv" command in global config for both gateways?

It is also advisable to check your clocking config.
