Hi all,

 

We're currently experiencing some problems with an analog fax after
transferring the gateway from callmanager 3.x to 4.1. The only thing
changed in the gateway was the IP-address of the callmanager.

The fax can receive calls, but when it wants to send it gets a
busy-tone. I checked the CDR Analysis and saw the calling number
together with the called number. I also noticed the originating device
(ip of the Cisco 827-4V) but it didn't show the destination device. At
first it seems to be a routing issue inside of the callmanager.

 

BUT........ the IP-phones (7960's) are in the SAME CSS as the h323
Gateway of the analog fax. Everyone can call internal as external

 

The situation:

 

FAX --> Cisco 827-4V --> IP-Cloud --> Callmanager --> MGCP-Gateway to
PSTN

 

========================================================

1 Cisco 827-4V which has 1 fax and 1 modem connected to it.

The dial-peer pots has a destination-pattern of 1234 and points to voice
port 1

The dial-peer voip has a destination-pattern of 0T and the IP-adress of
the CM.

========================================================

The config of the Cisco 827 on the CM (As H323 Gateway)

(Inbound Calls):

Significant Digits: All

CSS: CSS_LOCATION

Redirecting Number IE-Delivery inbound: Yes

 

(Outbound Calls):

Calling Party Selection: Originator

Calling Party Presentation: Allowed

Called Unknown: Cisco Callmanager

Calling Unknown: Cisco Callmanager

Called Numbering Plan: Cisco Callmanager

Calling Numbering Plan: Cisco Callmanager

Redirecting Number IE-Delivery outbound: Yes

========================================================

A Route Pattern 1234 (For the incoming calls to the fax)

Partition PT_LOCATION     (This partition is in CSS: CSS_LOCATION)

Gateway: IP of Cisco 827-4V

Call Classification: OnNet

========================================================

The Calling Search Space contains:

PT_LOCATION

PT_GATEWAY

========================================================

PT_LOCATION contains a Route Pattern 0.@ (For outside calls)

Route Pattern 0.@ points to a Route List which points to a Route Group

========================================================

Route Group config:

Discard Digits: PreDot

Routegroup points to the MGCP Gateway which is connected with a PRI to
the PSTN 

========================================================

 

Am I missing something?

 

Anyone in for this challenge?????

 

With regards,

 

Duncan Stork
