Vaak geen geluid bij inkomende gesprekken, geen rtp, sip udp timeout

[vakantieland.nl]

Omgeving: Snom370/8.7.3.25.5 achter Arcadyan VGV7519 met Firmware Version:02.00.125W4 (11.01.2013-11:01:22).
Op dit Telfort VDSL modem zijn een vast IP adres ingesteld voor het MAC adres van de Snom en zijn de navolgende poorten doorgestuurd:
1. TCP & UDP 5060
2. UDP 10000-11000

In de log van de Snom is kenmerkend ide foutmelding transaction_timeout udp: 1002386 (udp:185.29.203.27:5060) op het einde.

Enige vermoedens waar deze storing mogelijk door veroorzaakt wordt?

Ik ben niet technisch genoeg om het log te begrijpen, maar had gedurende een aantal weken wel ongeveer dezelfde problemen met one-way audio (zie http://forum.cheapconnect.net/index.php/topic,366.msg1433.html#msg1433. Na een upgrade van de firmware naar 02.00.132W4 (27.05.2014-15:50:52), aangevraagd via het Telfortforum, heb ik geen last meer gehad. CC kan trouwens debugging inschakelen om het verkeer te monitoren. Ik werk overigens niet met port-forwarding.

Dank voor je reactie.

Na een herstart van het modem en een uur of 4 later, staat er inmiddels zonder mijn tussenkomst nieuwe firmware op deze Telfort VGV7519.

Runtime Code Version:  02.00.132W4 (27.05.2014-15:50:52)

07/25/2014  13:29:57 TR069:Session end.

Ondanks de nieuwe firmware is het issue nog niet opgelost, nu komen de gesprekken soms niet eens binnen.

Een remote Fritz!Box meldt:
25.07.14 19:42:50 Internet telephony with 3115xxxxxxx via sip.voipbuster.com failed. Reason for error: User not found (404)

Het issue met het niet ontvangen van de inkomende oproepen blijkt te zitten in de manier waarop cheapconnect doorschakelt via "Follow me / Doorschakelen".

Ik wil meerdere toestellen op één telefoonnummer laten over gaan. Helaas kunnen er niet meerdere toestellen zich registreren op één Cheapconnect VoIP account.

Gevolg is dat ik met een timeout van 0 seconde naar de follow me lijst door wil schakelen, als daar vervolgens hetzelfde account (lees: telefoonnummer) weer instaat als waarop het toestel registreert, dan gaat het mis.

Ik ga nu van lieverlee dan nog maar weer een extra account aanmaken.
