Hello slw826,
I searched our online knowledge base and found this article with steps for not being unable to receive faxes from one number.
If you are still having issues after trying these steps, I suggest that you call into our support department for assistance @ 1-800-821-2797 or 1-800-835-6100
We are having issues sending and receiving faxes with only one of our contacts. We get a fax cumminication error with a code of 035-705, We can send and receive faxes with all other contacts. We have no idea how to resolve this. Any suggestions would be greatly appreciated.
