Good morning Christopher,
You know... I'm a technical guy... but sometimes cause and effect eludes me...
After playing around a while with your suggestions it turns out disabling "AAC-ELD 16kHz" in the audio settings solves the issue?!?!?
I can understand why a not supported codec can result in a "call failed".
But how is it possible, that an audio setting is OK for local (inner-country) calls but wrong for international?!?!
Do you have any clue?
Anyhow... thanks heaps for the awesome help with my issues.
Thanks again!
Soko

488 not acceptable here can be due to codec problems. In the SDP in the initial invite, I don't see any G.711 A-law or U-law (aka PCMA/PCMU) listed - only Speex, iLBC, AAC and Opus plus the usual signalling telephone-event stuff.
Chances are your new telco provider may not wish to transcode to G.711, so is refusing the set up? Settings -> Audio -> PCMU/PCMA at the bottom. I'd expect to see
a=rtpmap:8 PCMA/8000
a=rtpmap:0 PCMU/8000
peoplefone supports the codecs G711a/u, G722, G729. We also support the T-38 protocol for fax. (Please contact us, if you want to use it.)
Please try to follow the order in the configuration if possible:
Sidenote - although you appear to already have it disabled, if you have problems establishing calls in future make sure you the video feature is disabled ("always use video" on the desktop, "Enable video" in the mobile client).
Video requires RTP/AVPF profiles to be sent in the SDP, which some SIP proxies don't like. Your invite appears to be OK though (RTP/AVP), except for the lack of G.711 codecs advertised in your INVITE.

Hi Sylvain,
Sorry, I've made a wrong assumption. I had an old SIP line from a
different provider in Linphone and didn't know that dailing from the
history also dails the old provider.
So the real issue is apparently:
I cannot dail international numbers with Linphone and peoplephone.at.
Non-international numbers work! With an other App (Zioper) or another SIP
line (localphone.com) everything works.
- Changing the setting "Subsitute + in phone number" doesnt make a
difference
- In the setting "Country code prefix" (if this setting is from
importance) I have tried "+43", "0043" and "0" (country I'm in). Somehow
it doesnt take "" as an entry.
The error is still the same:
Call failed
Cannot call + +4935...9915
Reason was: Not Acceptable Here
[Media Descriptions Syntax error while parsing the SDP]
Find attached the log file.
thanks
Soko
