One Way Speech on TP Link T1600G-28PS
Hi There
I have a Hosted Handset which works perfectly fine plugged into my router but i would like to use my PoE Switch [TP Link T1600G-28PS] so that i dont have a power cord into the phone.
The phone loads up fine, receives and makes calls but the caller is unable to hear me [i can hear them]...
I dont suppose anyone knows how to resolve this ? does the switch have built in SIP ALG ?
Thank you in advance.
