First post and not sure if there is a better category, so apologies in advance.
We are trying to route outbound calls to a DAHDI trunk to go out via a landline on a Sangoma A200 card. After dialing the full number, it gives a second dial tone. Adding 1 or multiple w’s to the Outbound Dial Prefix for that trunk causes the proper delay, but still gives second dial tone.Dialing the same number again goes through with proper caller id indicating it went out the right trunk. How can we make the call go through without the second dial tone?

CentOS release 6.8 (Final)
We have two phone servers in this office. IP phones are connected to the new phone server, but landlines have been going out from the old phone server. We have outbound routes to a local trunk to the old phone server, which works correctly.
We now want to swap the landlines to the new phone server. We have a sangoma A200 card in each server. We started with a separate line in port 4 on the new phone server. The other 3 ports have nothing connected. We created a DAHDI trunk to this landline port. It is called Landlines1 and in FreePBX it has CID Options set to Allow Any CID, Asterisk Trunk Dial Options set to Tt, no dial rules or outbound dial prefix, DAHDI Trunks set to Analog Channel 4 or Group 0 Round Robin Ascending behave the same way and no other settings filled in.
The old phone server is an older version of asterisk and FreePBX and its ZAP trunks have a text box for Dial Rules rather than the new style Prepend, Prefix, Match Pattern. The Dial Rules for each trunk entered in this text box is *3x|. to strip off a custom dial pattern to select a trunk, then pass the actual phone number to the trunk.
Does anyone have any ideas why we’re getting a second dial tone and how to send the number immediately?
