Dear Cisco community,
I hope someone can help me.
Our service provider Deutsche Telekom recently wrote us that we will not be able to make calls any more within short term.
The reason they give is that our hardware (Cisco / Linksys PAP2T) is using a DNS config via A-Record. This will be supported by Deutsche Telekom no more.
Instead, they say we need to use a DNS config via SRV.
I already found out that Deutsche Telekom requires to register at their server "tel.t-online.de" with Port 0.
So, the entry in PAP2T needs to be something like "tel.t-online.de:0" or similar. And it seems that "DNS via NAPTR" needs to be specified.
I have no idea if PAP2T supports these requirements.
Maybe someone can give me a hint.
Thanks in advance.
Kind regards
BTG
