ATA and faxes issue

[shiblyibrahim]

I configured an ATA. Its a CME based system. CME version 8.6

I tested inbound and outbound faxes and it did work. But customer complained that some of their suppliers are having issues sending faxes to them.

I tested once the fax went through and another time it failed. It seems quite intermittent.

Any suggestion would be appreciated. Please find the config below

Hey Chrys,

Thanks. I was making the changes and in the meantime I had a tac case logged with cisco. She said I wouldnt need the dial-peer at all since the analog device would be a device part of the system and therefore the dial-peer is not necessary.

I have removed it and tested twice waiting for customer to get back to me on this.

Chris by the way thanks for the help. If this doesnt work I am going to use your solution and see.
