Voxalot / SIP Broker Support Forums - View Single Post - me too: sometimes only oneway Audio (VoipCheap-Voxalot-ATA)

I have also just started to notice this problem with voipcheap.com. Need to try a second time to make a call - first time the person I am calling can't hear me.

I am suspecting that after making no calls for a while that my first calls audio is failing. (perhaps the NAT setup is getting lost after a while due to my settings)

My setup in case anybody with same problems notices anything similar

Linksys WRT54GL router using NAT with ports 5060-5061 forwarded to Linksys PAP2 ATA with Static IP
Voipcheap.com via voxalot (not registered)

Symetric NAT = on - optimise audio = yes - just turned these off as recommended in the post above will let you know if it helps.

As requested above my setting are as follows but remember that my setup has been ok for over 12 months

Handle VIA received: NO
Handle VIA rport: NO
Insert VIA received: NO
Insert VIA rport: NO
Substitute VIA Addr: YES
Send Resp To Src Port: YES
STUN Enable: YES

STUN Server: stun.voipcheap.com:3478
NAT Keep Alive Intvl: 28

NAT Keep Alive Enable: YES

NAT Keep Alive Dest: $PROXY
