Hello Venkat
 
If Customer INVITE contains G.711 ulaw codec in codec list then in this case call got connected and both way voice .

Hello Guys , 


Pls share your thoughts whether the below scenario is right behaviour .


Customer  - > Softswitch - > Supplier .


1. Customer invite has codec G723 , ilbc etc .
2.Supplier is responding back with only G711ulaw codec which was not offered by Customer .
3. Call got connected with voice on both sides .


Thanks ,
Venkat
