analog line problen with DTMF

[glazo]

Hi, everyone!

I have a really strange situation with analog lines. After a match is found for outgoing call short code any button pressed generate strange noise, similar with DTMF but with interference. If i use Phone Manager to make a call, i get same behavior after call answered at destination. When i connect analog phone direct to the line, DTMF work's just fine.

List of equipment and settings:
IP Office 500v2 R7.0.31.
ATM16 expansion module.
Phone30V2 expansion module.

9N/Dial/N/ARS - outgoing call short code.
?/Dial/./Analog Line Group ID - short code in ARS, other setting's is default.

Analog line settings:
Trunk Type: Loop Start.
Signaling Type: DTMF Dialing.
Direction: Bothway.
Other setting's is default.

I'm sorry for my English

If it is not preventing you from dialing and you can use DTMF to navigate through an automated attendant you should probably ignore it.

Run the Automatic Balance Impedance Match Wizard on each of the trunks individually and use the value it comes up with. There are some other settings on this tab you can change but if it allows you to dial you probably should not change them.

Unfortunately it is, in my region "Automatic Balance Impedance Match Wizard" is not available, but I try in Customize locale, thank you for this tip, this situation is really drive me crazy.

I will answer to my self, port change for ATM16 expansion module helped, looks like one of IP Office ports was burn out.
