[cisco-voip] Fax-problems through H323 gateway and CM: Incomi ng Yes, outgoing No.

[Stork, D.H. (Duncan)]

The IP-address in the H323 is the IP of the CM and there is IP-connectivity
from the 827 to the CM.
I haven't tried the debug h225 q931 yet, but the debug voice ccapi inout
gave me an ISDN-errorcode of 0X1 (unallocated number). 
I don't think MGCP can be involved, because all the IP-phones can make
outside calls and they are in the same CSS. I think the following makes it
more clear than my previous scheme:
 
   
CSS_LOCATION

Hi,

 

Check IP address of CCM on h323 gateway.

 

What display debug h225 q931 on 827 and  debug ccm-manager backhaul on MGCP
gate ??

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
