RE: Long Tone on Outbound Calling
Im experencing the same on a T38g w/ FW (have tried upgrading several times). Any fix/workaround??

This started happening when we changed the trunk lines to some Grandstream 4fxo ATAs. I tried recording calls and it seems the long been is produced by the phone itself since its not on the audio channel recorded by the PBX, neither the other party hears its. This is just on outbound calls and with Yealinks. Internal calls dont do that, neither other brands of phones dialing outside. This behavior even gets reproduced over IAX trunks that use this Grandstreams ATA FXO

Yealink Phone ---- PBX B ----- (IAX TRUNK) --- PBX A -- Grandstream GXW410X

Yealink PHone ---- PBX A --- Grandstream GXW410X

On both cases users report this issues, like 70% of their outgoing calls


Ive attached a log... the number dialed when this happend ends with 0033 Let me know when the logs are downloaded so I can removed them from the post

Attached File(s)
.bin  config.bin (Size: 215 KB / Downloads: 0)
.tar  syslog (3).tar (Size: 181.5 KB / Downloads: 0)
