[asterisk-users] Voicemail cutting out after about 30 seconds

[Steven Howes]

Hi,

We saw this between Asterisk and an Audiocodes gateway. Whilst the  
voicemail is being recorded asterisk is not sending *ANY* rtp. Silence  
detection will always detect silence if it listens to this side of the  
conversation. Adjusting the threshold wont work, you need to find the  
timeout for the gateway which is doing it (not always easy...)
