Voice delay on in-group

[btaveras]

Hi,

I am facing a rare issue with the voice when a call goes to a specific ingroup I have voice delay of 2-3 seconds, but if a call goes to a the call menu and then I dials a extension directly the calls sounds perfect. I really don't know what is the problem, not even where to start looking.

I am using the regular codecs alaw and ulaw.

I'm ussing asterisk Asterisk 1.4.39.1-vici.go
