[cisco-voip] Fax issues

[Ruben Montes]

Hello,

I have an ATA with a FAX. The CCM cluster has a MGCP gateway which is connected with a E1 QSIG to a PBX MD110. 

If I send a fax from a fax located in the PBX side it works, but if I try to send a fax from an external location, this fax enters through the PBX and the PBX redirects it to the QSIG trunk.

When it doesn't work I have this error in the debug isdn q931:

Any idea??

Thanks,
