[Freeswitch-users] mod_dingaling answering prematurely

I just got mod_dingaling working for outbound and inbound calls. However, on inbound calls I have to answer it quickly on my SIP phone. When I do I catch the call screening announcement from google to press a "1" to answer. I put the "execute_on_answer=send_dtmf 1" as recommended in the Wiki which eliminates the need to press one. It seems that FS is answering the call and google starts playing the screening. If I wait too long to answer I miss the announcement. I am routing the call to a specific extension for testing. The dialplan is using the extension definitions provided in the default configuration. Where should I start looking to allow the phones to ring longer and not prematurely answer the inbound call? Thanks, Jon
