Sl-1000 incoming call audio issue fowarding to mobile phone

[Zero6]

Hi all,

An SL-1000 is programmed to forward calls to a mobile phone after hours, so when the office closes the calls go to a mobile phone at 7pm.
When the client receives on the sl-1000, it forwards the call the his mobile phone, he hears the caller at a very low volume and the caller doesn't hear him at all.

Does anybody have an idea what might causing this issues and how they can be fixed?

Thx in advance

14-01 has gain and loss setting for the trunks. You should also see separate gain and loss settings for transferred calls. Playing with those settings should help, but if the volume is that low you likely have line problems the telephone carrier needs to address.
