Cisco 2801 with one BRI calls drops

Unanswered Question

Hi,

I have one 2801 (IOS 14.4.15T8) with one BRI the problem is that many calls (inbound ou outbound) trough BRI gets dropped

My config:

network-clock-participate wic 0

network-clock-select 1 BRI0/0/0

interface BRI0/0/0

no ip address

isdn switch-type basic-net3

isdn overlap-receiving

isdn point-to-point-setup

isdn incoming-voice voice

isdn sending-complete

isdn static-tei 0

Usually in another configs i use static tei with no problems.

Layer 1 and Layer 2 are UP in BRI with no calls.

I see a lot of %MARS_NETCLK-3-CLK_TRANS in logging when calls are dropped layer 2 goes dow.

Any suggestions?

Best Regards

MC

I have this problem too.

Can you a try a different IOS ? like YB4 for example.

Note you or may not have static tei, ask telco.
