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.
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?
