Telphin SIP trunk setup

How to connect Telphin to your PBX: SIP server, port, login, codecs, number format and a ready pjsip.conf for Asterisk, a FreeSWITCH gateway and the fields for 3CX. The generator fills in your details.

SIP servervoice.telphin.com (a regular line); your Telphin.Office address for a cloud PBX extension
Port5068, not 5060
AuthenticationRegistration
LoginLine number like 000xxxxx; for Telphin.Office extensions SIP ID like xxxx*101
Provider guidewww.telphin.ru

The non-standard port 5068 is the most common reason a Telphin trunk does not register: check it in the AOR contact and the registration server URI.

The * in Telphin.Office logins is a normal character: keep it in the username.

Generator with Telphin settings

Provider fields are filled in: add your login, password and number.

If it does not work

Check whether the provider server answers: SIP check. Read a registration or call log: SIP log analyzer. No audio: NAT test.
