The aim of this project is to provide a working SIP daemon for Lantiq SoCs with MIPS CPU.
owsip utilizes available FXS hardware ports for making calls.
Once owsip is only and registered you can start to make and answer calls. SIP can dial landline and sip numbers. Currently a number dialed on a key pad is interpreted as a landline. If you want to call a sip account, you need to add a contact entry for this. To dial a contact, simply press the “*” key followed by the “code” sequence. Note that owsip can do keypad letter → number conversion (for example → 3926753).
The “#” key is also mapped to handle dial backends, however “contact” is the only backend we currently have. it is mapped to “#1code”.
