CallManager 4.1 router 2811 and FAX problem

Hello,

We are using CallManager 4.1 and router 2811.

We are using the router to get fax using:

dial-peer voice 833 pots

service onramp

incoming called-number XXXXXXX

direct-inward-dial

port 0/0/0:15

!

dial-peer voice 803 mmoip

service fax_on_vfc_onramp_app out-bound

destination-pattern XXXXXXX

information-type fax

session target mailto:user@mydomain.com

Some time the tif come corrupted.

from the same fax some time it's come with no problem.

any idea?

Hi,

can you check "show controller E1" ?

Most likely you will see that have slips.

To fix:

network-clock-participate wic 0

network-clock-select 1 E1 0/0/0

Does it helps? If so please rate post and check "solved" as appropriate!

Re: CallManager 4.1 router 2811 and FAX problem

Unfortunately, you have no slips that are the most common cause of fax trouble. You can configure the clock but that should not affect anything.

Finding what is the problem now may become difficult as it involves not just regular faxing but the fax-to-email feature too.

You may end up finding that fax sent from some machines are ok while others are not.

I suggest you contact the TAC and ask for an specialized team. be prepared to produce lot of traces and pressure to have them reproduce the problem in lab.

Good luck!
