RE: T38G Continues to ring after outbound call connects

I'm not sure if this is phone specific as most of our phones are T38G's.

When calling a remote party from a T38G (via asterisk) over public WAN we often experience connection difficulties. I would estimate 40% of the time. Sometimes the problem can not present itself for a week or so and then reappears.

The problem is with remote phones calling into the asterisk server / T38G phones.

When a call is placed from the remote phone into the office and the call is answered, the remote calling party hears speech but the phone continues to 'ring', i.e. the remote party still hears ring tone in the ear and the phone continues to show the animated arrows typically seen when calling.

Phones are running firmware 38.70.0.172 as we make use of multicast IP and I cannot be sure if there is any updated firmware available that supports this.

Any help would be much appreciated.

Thanks

Steve

Hi Steve

Please kindly upgrade to this firmware to check:

For your question, let me check again with you:
1. PBX is on public network. May i know the yealink is in public network or not.
2. use mobile phone to call yealink phone, yealink phone answer and it will show time(00:00,00:01,00:02), but on mobile phone, it will still hear ringtone.
3. This issue will not happened everytime.

To solve this issue, i need pacp,syslog,config.bin files to do more troubleshooting.
For how to export those files, you can refer to this FAQ:
http://support.yealink.com/faq/faqInfo?id=311
NOTE: you should reproduce this issue, so that you can get useful files to me.

May i know how many phones in your side? How many phones have such issue?
