             Summary: Incoming audio not working
                 Key: ASTERISK-24320
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24320
             Project: Asterisk
          Issue Type: Information Request
      Security Level: None
    Affects Versions: 1.8.9.3
            Reporter: Siva

Hello
We are using asterisk 1.4.10.1 with digium gateway G100

Due to problem with our old redfone T1 gateway we replaced with digium g100 gateway.

After changing the digium G100 Outgoing is working fine but no audio for incoming calls, even no sound for ivr, voicemail greetings, busy message and voice mail messages.

I tried all possibilities and created ticket with digium support as well for g100 they checked and i was told there is no problem with g100. Issue seems to be in asterisk, thing is it's working fine with redfone T1 gateway.

Below is my sip.conf. Do we need to configure any thing specific for incoming audio to work with g100?

[digiumtrunk]
type=friend
username=digiumtrunk
secret=digiumtrunk
host=10.14.0.29(g100 ip)
context=incoming
qualify=yes
disallow=all
allow=gsm
allow=ulaw
nat=yes

I tried with nat yes, no and never options in sip.conf
