Dear Experts,

I have PRI line I use it to provide phone and fax lines.

The Fax lines are NOT working well specially with long distance numbers.

Should I configure the CallManager some how to fix this OR should I configure the Standard ATA 186 itself?

Dear Mhendren,

Thanks alot for your fast response.

I tries this before but I still have problems.

Shouldn't I tune the ATA itself?

I haven't had to tune an ATA before so I really don't know on that.


When you say it's not working well, what is meant by that? Are calls dropping? Not dialing?

As mentioned in the duplicates of this thread,


Post here output of "show controllers E1" or T1.

Add network-clock-select 1 e1 0/0/0 (fit to your needs) if you have slips on your T1/E1 in show controller t1/e1


Otherwise, make sure you have this configured for H323:


voice service voip

modem passthrough nse code g711ulaw


and this for MGCP:


mgcp modem pass voip mode nse

mgcp fax t38 inhibit



You also want to set these parameters on the ATA:

audio 0x00150015

connect 0x0900400
