[asterisk-users] Asterisk Avaya SIP Trunking One Way Audio

[Shariq Khan]

I am facing one way audio problem in sip trunking between asterisk and
avaya.

              +-------------+       +----+
              | avaya sip   |-------| P1 |
              +-------------+       +----+
                     |
                     |
                     |
              +-------------+
              |  Asterisk   |               WAN
-------------------------------------------------
              |             |               LAN
              +-------------+
                 |
                 /
       +----+   /
       | P2 |--+
       +----+

When P1 dial P2, P2 hears voice clear but P1 could not hear any voice.

My sip.conf is

[avaya]
type=peer
fromdomain=xx.xx.xx.xx
host=xx.xx.xx.xx
disallow=all
allow=ulaw
dtmfmode=rfc2833
canreinvite=yes
