Exclamation T48G +- 20 second delay outgoing calls
Hi there,

At this moment we are using 7 T48G phones in our company. We have a couple of issues, but the main issue I would like to solve immediately is the delay issue.

General information:
- firmware: 35.7.0.50
- Hardware version 35.1.0.2.1.0.0

What is the scenario:
- Make an outgoing call
- Receiver picks up his phone and doesn't hear anything for the first 15-22 seconds
- Both phones know the call is successful ( timer is counting up )

Kind regards,

Jens Van Herck

for this issue, is the scenario like below :

1. A call B, B answer , A and B establish a call , TIME IS COUNTING UP
2. at this time, A speak hello..., then 15-22 seconds later , B hear the hello ......,

Hi Michael

For the scenario:
B does NOT hear anything A is saying during the first 15 - 22 seconds. The words before is missed.

Did a factory reset yesterday, didn't solve the issue.
I will read the FAQ now to send you the files.

Kind regards,

Jens Van Herck

Hi Michael,

mail has been sent with the additional files.

Kind regards,

Jens

Hi,

We had this problem before. the first thing to do, is to contact the carrier. to see if the call request comes in to him at the same second when you started the call. like that you could see if the problem is with the hosted machine sending the call request late, or with him routing the call late.

All the best,
Abe

Which Router and Firewall are you using?

Hi,

I have sent my trace files to Yealink R&D. I'm waiting now for an answer ( 7 days ago ).

Thanks
