    Unhappy VR 2600 v - Phone Calls are not completetd

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Hello.
    Since 2 month I am using the TP Link VR 2600 v Router with German Telekom as ISP.

    Internet and phone is working but ...

    I need help with the following problem:

    --> If I want to make phone calls, it occurs, that these calls are not completed.
    I dial the number,
    I can hear the sound of dialing
    ... than - after a certain time - the line is mute and I hear the "occupied" signal.

    I called my ISP (Telekom) and we figured out, that this happens, if the number I want to call is located by the German Vodafone.
    If I call the same phone number by using a "call by call" provider, the call is completed correctly.

    Can anybody please give me a hint or the solution ?

    Thanks and kind regards.

    try to diable SIP-ALG under NAT forwarding--ALG.
    have you asked telekom why the call is not completed if you call German Vodafone.? they should be able to tell you more info.

    I have same problem. They say it depends on codec. vodafone does not support PCMu. I cant find where to choose the codec.

    i can't find codec in the menu, either.
    but you can try disable SIP-ALG under forwarding--ALG settings
    also enable voip qos under QOS--put voip on the high priority list.

    i think it is better to contact tp-link support so they can solve this issue.

    VR 2600 v - Phone Calls are not completed

    Thank you all so far for your answers and hints.

    @ Kevin SG
    I tried your advice and have disabled SIP-ALG.
    No difference. The problem continues ...

    @ Shield101
    Tested your hints too. no difference. The problem ist still the same

    I have been in touch with the technical dept. of Telekom and they tested my line. Everything fine.
    I have installed and tested an original Telekom router an a Fritz-box on my line too. With both the problem was not detected.

    Therefore I am sure up to 99 %, that it is a problem with the TP-Link router

    @ vieldcs
    I'll do that and inform the TP-Link support.

    If anybody has an other idea, please ...

    Kind regards and happy Easter days

    Thanks to all for your answers and hints.

    I made the modifications as suggested from Kevin and Shield - but there was no difference. The problem still continues


    I have contacted the technical department of German Telekom. They have tested my phone line and told me that everything is o.k.

    Also I made two tests.
    At first with a original Telekom router and than a secound wit a Fritz-box router.
    In both tests the problem was not detectable and present.
    Connecting again my TP-Link router the problem returned.

    Therefore I am 99 % sure, that it should be a issue of the TP-Link router ...

    Anybody has further ideas or hints ?

    Thanks for your replies and nice Easter days !

    I have the same problem as Alex (you are not alone! . Provider is also German Telekom.However, I suspect that the not working numbers are of people with "ISDN numbers" (so not SIP, VoIP yet).The problem is present for at least 3 month. Can we get a statement from Tp-link? Thank you!

    Finally I received today a Beta-Firmware - after a log period of 5 weeks.
    It seems to work now and as the problem is solved temporary ... until a final Firmware will be released.

    As described it is a Beta Version ... so I am not sure if I may spread the link here.

    My recommendation for all users (e.g. RLink ) which have the same problem:
    --> Get directly in contact with TP-Link by support.de@tp-link.com

    Thx for the help here :-) and kind regards,
    Alex
