Hi,

I have an ISDN voice gateway and a SIP trunk connecting to another system. I see the following when I enable debug ISDN q931

*Mar 21 10:56:25.290: ISDN BR1 Q931: RX <- SETUP pd = 8  callref = 0x70
        Sending Complete

The IOS gateway is sending many PROGRESS 8 values, but in another site from this customer with similar configuration, the gateway doesn't send so many PROGRESS  messages.

Any idea?

Thanks

Hi,

This is due to the following:

      Calling Party Number i = 0x0181, 'XXXXX'
                Plan:ISDN, Type:Unknown
      

This IOS is detecting that the calling number is not in ISDN format or not detecting this as a known number.

Hello Amit,

This customer will have around 40 remote sites, and we have now installed half of them. All configurations and hardware are similar. I shall connect to some other remote sites, and check the ISDN debug. Although I am sure I didn't see so many PROGRESS messages on other sites, but I don't know what I saw as type plan

Thank you for your help

Jan

Probably, you can test it by correcting the Type and the Calling party number to some number, rather "XXXX" for eg. the message :

Calling Party Number i = 0x0181, '8232001'
                Plan:ISDN, Type:Local

This gateway connects with a SIP trunk to another device. This device sends multiple SIP session messages, and the Cisco gateway sends a PROGRESS for each of this message

So issue with SIP, there is not a problem, it works, just a little weird to see so many messages.

Thanks for the responses
