TDM switching BRI with Polycom

Hi


I want to configure a TDM switching BRI to PRI and PRI to BRI video calls with 2 bri ports but i have the following issues:


1) The incoming call was sucessfull but only at 128 kbps, when de

the caller try the video conference to 256kbps but finally completes at 128kbps.

2) i can´t place BRI calls to the PSTN, with the debug q931 the result is :

        Cause i = 0x8281 - Unallocated/unassigned number


The PSTN PRI send the last four digists, so the BRI line is 9005.


The configuration:

Re: TDM switching BRI with Polycom

Configure as below.

regarding the calling out issue, you need to take "debug isdn q931" with "term mon".

interface BRI0/3/0
no isdn tei-negotiation first-call

no isdn supp-service name calling
no isdn negotiate-bchan
no line-power

trunk-group bri
!
interface BRI0/3/1
no isdn tei-negotiation first-call

no isdn supp-service name calling
no isdn negotiate-bchan
no line-power

trunk-group bri

Re: TDM switching BRI with Polycom

You have something wrong in the configuration, like the corlist blocking.

Re: TDM switching BRI with Polycom

This is the configuration running in the router, do you have any idea?

There are any posibility that the problem is associated with the telco?

Thanks

Check:

      outgoing COR list:SalidaNacional

Note I think can do without 0 in Spain. Users like it.

Re: TDM switching BRI with Polycom

As mentioned already, you need to take debug isdn q931 when having a problem.

Then you mentioned it was something else and low-rated my posts ?

For once i will put my answer in spanish for better chances to be understood:
