Sometimes users can't receive calls from public network, checking the gateways during the problem we got something like:


voice_gtw#show voice port summary

IN OUT

PORT CH SIG-TYPE ADMIN OPER STATUS STATUS EC

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

0/0/0:1 01 r2-digital up dorm idle idle y

0/0/0:1 02 r2-digital up up answered idle y

0/0/0:1 03 r2-digital up dorm idle idle y

0/0/0:1 04 r2-digital up up clearfwd idle y

0/0/0:1 05 r2-digital up up clearfwd idle y

0/0/0:1 06 r2-digital up up answered idle y

0/0/0:1 07 r2-digital up up clearfwd idle y

0/0/0:1 08 r2-digital up dorm idle idle y

0/0/0:1 09 r2-digital up up clearfwd idle y

0/0/0:1 10 r2-digital up dorm idle idle y

0/0/0:1 11 r2-digital up up clearfwd idle y


We noticed that a lot of ports remains at clearfwd at IN STATUS.


Shutting and bringing up the controller makes it work fine again and calls from everywhere can reach the users again


Anyone knows what the "clearfwd" status meam ? After the controller recycle the status of "clearfwd" suddenly disapear ! Taking advantage from this post, anyone knows a documentation that explains everything about the "show voice port summary command" ?

Ricardo

this user setting for R2 Brazil may help you as well.


Hope this helps, please rate post if it does!

Hi,


This is very useful, I took a look at the post you've said and I've found a lot of "possible" answers to this problem.


I will work on it and as soon as I solve it I would post the solution used.


Again, thank you so much !


Regards,

Ricardo
