Sad Long Tone on Outbound Calling
Whenever a user dials out, the user hears a very long (and loud) dtmf tone played out (over the handset or speaker) for a good 5+ seconds during initial callout over the ringback on the line (analog), and then goes away (doesn't matter if ringback continues or hits automated attendant). Any idea what might be causing this?

Thanks,

RE: Long Tone on Outbound Calling
Hello,
1.Do you make a VOIP call, or make a PSTN call with T22p/T28p ?
2.This long DTMF tone play together with ringback tone? Or play long DTMF first, then play ringback tone?
3.Could you try to disabled "180 Ring Workaround" in the phone webpage-Phone-Features-General Information?
4.You can also try to upgrade to our latest V71 firmware to check again.

5. If the problem is still, could you provide PCAP trace, syslog(level 6) and config.bin file to us, so we can analyze?
Before you export the syslog, please set log level as 6, and reboot the phone, then click Start,and reproduce the issue, then click Stop,and export the trace, syslog, config,bin to us.
(About where to export these files, please refer to attached screenshot.)
These three files are very important for us, hope you can kindly understand.
Thanks.

RE: Long Tone on Outbound Calling
1. This is an outbound PSTN call w/ T22P & T28P onsite
2. The DTMF is over the top of the ringback (i.e. together)
3. Just set '180 Ring Workaround' = Disabled
4. Just upgraded from v70.150 to v71.140
5. I will attempt to run capture...

Xa. I also just set 'Features > General > Play Local DTMF Tone' = Disabled
Xb. I also just set DTMF Type to 'Inband'

Now instead of a long ~5sec tone, it's a short ~1sec beep (still bad)... not sure what else to do, will see about getting the capture.

T22P & T28P (v70)
DTMF is set to RFC2833

I'm having the exact same issues, here is my description of the problem.
Yealink T22 & T28 Failures: An intermittent loud DTMF tone of approximately 2-3 seconds in duration is being generated over the ringback tone on outbound calls, the tone does not affect the call other than to be an extreme annoyance to the Yealink caller as the tone ceases as soon as the called party answers, the frequency of this failure is approximately 50% and except for the annoying intermittent tone on outbound calls all other phone functions seem to be unaffected. The T28 phones are version 2.70.0.141 and the T22 is version 7.70.0.150 that was upgraded from 7.70.0.141 and didn't change the issue.

Any Ideas?

I downgraded the T28 phones from version 2.70.0.141 to 2.61.0.80 and the DTMF tone decreased from about 5 seconds to about .5 seconds.

When can I tell my customer that you will have a fix for this?

RE: Long Tone on Outbound Calling
Hi
Try to upgrade to V71 and reset to factory
T22:http://www.yealink.com/Upload/T2X/T2X-V71/7.71.0.140.zip
T28:http://www.yealink.com/Upload/T2X/T2X-V71/2.71.0.140.zip
T46:http://www.yealink.com/Upload/T4X/GA/28.71.0.170.zip
If the problem is still, could you provide PCAP trace, syslog(level 6) and config.bin file to us, without these we can hardly confirm the problem and submit it.

Before you export the syslog, please set log level as 6, and reboot the phone, then click Start,and reproduce the issue, then click Stop,and export the trace, syslog, config,bin to us.

RE: Long Tone on Outbound Calling
Im experencing the same on a T38g w/ FW 38.70.1.33 (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

Update:

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

RE: Long Tone on Outbound Calling
Hi, the problem seems very similar to what described in this post:

http://forum.yealink.com/forum/showthrea...hlight=GXW

Can you have a try of upgrading Grandstream gateway?

Regards,
James
