We're having issues with faxing outbound with a fax machine hooked directly to an FXS port. After all digits are dialed we receive a fast busy. Looking at debug voip dialpeer, I see where each individual digit is dialed and then when they are all dialed it successfully matches our outbound 9T dial-peer. We are able to make inbound calls/faxes to this it's just not working outbound. We also tried a phone hooked to this cable and were able to receive a call but not make a call. Unfortunately I didn't save the debug voip dialpeer results.
Below is part of our configuration:
voice translation-rule 1
rule 1 /2300/ /6800/
rule 2 /2201/ /6801/
rule 3 /22/ /22/
rule 4 /23/ /23/
rule 5 /..../ /6750/

To anyone with this issue, I was not onsite dialing at the time and the person I was working with was dialing a 1 after the 9 for an outside line which the telco was rejecting. Without the 1 the call completed successfully.
