[Freeswitch-users] Freeswitch Sonus bypass media

Dear All, i've read in past or may be still Freeswitch and sonus are not good with each other . but every post shows its always rtp between FS and Sonus. In my case i am bypassing all media , so just signalling between US (using FS) and Provider (Sonus) . And ACD is extreme low as 4-5 minutes due to 100s of short calls ending with normal call clearing. Can any one Please help if in bypass still FS and Sonus can have some problem. Thanks in advance regards soFh
