None

Hi, I have a strange problem with this configuration, while calling an external phone they hear broken words, as if you lost the first part of the words, like old vox systems, how can I solve it?

Hi Daniele,

Did you check codecs on PBX and Phones? Try enabling same codecs order: 711a - 711u. Are you using RTG, ISDN or SIP outside trunks?

Hi Daniele,

I'm also in Italy, has the ISDN only one number or it has two or more? Did you try to set volume level on RT line configuration at 100%? It happens always, I mean, with incoming calls or also with outgoing calls?
