Fax lines just keep ringing

[HillyardK]

We have fax lines setup that are connected to VG224.  Recently more and more of the fax lines just ring.  We never get to the fax tones.

We have been working with our provider and Cisco and no one can figure out what the issue is.  And with VG224s being EOS, they won't go into them extensively.

Most of the programming on the VGs have been there for 5+ years. 

Also, our former voice engineers programmed the VGs that random ports are SCCP and some are MGCP.  I have one that has ports 12, 14, and 17 as MGCP and the rest are SCCP.

Does anyone have any ideas as to what I need to look for, try or ask our provider to look for in CUCM?

Hi,

Did you try to disable ECM on theV VG?

no mgcp fax ecm

Can you also specify which kind of PSTN line are you usig?

Thanks a lot

I have been comparing the config with another one that is working and no mgcp fax ecm is not on either of them.

Kind of PSTN line we are using - so you mean E or T1?  Honestly not sure.  When we moved to our managed provider we ported all the numbers over to them.

Hi,
Yes meant the carrier link type.
Can you please activate a debug vpm signal and debug vtsp tone while calling a fax and post here the output?

Thanks

Regards

Carlo
