Hi George,

Unfortunately I wasn't able to configure the IP Fax the way I wanted, I also contacted the TAC but the only thing we were able to set up was a feature for sending out faxes from an exchange account, however when we try to receive a fax from the pstn using unity, it didn't work and as per Cisco's words, it was not supported, if you want the configuration we used with the IP Fax for sending faxes then let me know.

Regards,

Carlos.

Hi Carlos,

Thanks for your response. Incoming fax works to specific extension. I am looking over this url recommended by Partner Help:

http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide_chapter09186a00800b5dc4.html

The router needs to detect that the call is a fax and then forward it to the exchange.

Please post the config just for reference.

Can you also give the case #?

Thanks,

./G

P.S: I will test fax detect and let u know

Also, I haven't heard about the call detection, probably this is why my configuration didn't work, I'll give it a try, probably it works only with one subscriber, main issue here is that my customer wants to have all the subscribers with their DiD's working this way (Fax and Phone).

The case number is 605675651.

Regards,

Carlos.

P.S. If your test is successful I'd appreciate to know how did you configure it.

Hi Carlos,

I have managed to get this work!

A fax detection tcl script must be configured on the incoming matching pots (pstn) dial-peer. There are four modes for detecting fax, either by CNG (gateway waits for 9 seconds for the appropriate tone fax/voice) and/or DTMF (through IVR prompt).

FYI:

http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide_chapter09186a00800b5dc4.html

http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide_chapter09186a00800b5dc4.html#wp1082248

There are several advantages/disadvantages over each mode discussed above.

The good thing is that it is doable but I expect some false positives on fax detection especially with faxes before 1995 or delayed dialtone detection.

This is not a very convenient way of doing this but is the only way :). I am waiting for cisco if this is supported officially

Hi George,

Thanks for the information, I will give it a try on Friday and will let you know the results.

Once again thanks :)

Thanks for your response. I have the same config

but the smtp server points to the exchange server. Also my question is whether we can have each user extension to receive fax in its mbox using the same extension as his phone.

./G

What would cause only the first page of a multi page inbound fax to show up in a persons mailbox?
