Looks like CDMA is not fully supported for the voicecall yet. What I see from ofono master branch there are only probe, remove, dial, hangup had been implemented. I am working on other's method step by step. I am wondering is it worth it to change the dbus service path from org.ofono.cdma.voicecallmanager to org.ofono.voicecallmanager? In this case, application doesn't need to care about it's GSM modem or CDMA modem, what they need to do is connecting to the same dbus path.

The service path is always the same, org.ofono. What you're referring to is the dbus interface name. > to org.ofono.voicecallmanager?

No, the API has been specifically designed to separate CDMA and GSM details. There are too many differences in the two systems and their respective capabilities to mash them together.

For example, ofono_voicecall_driver has methods like dial, answer, hangup all, hold_all_active...etc, I believe cdma will have almost same methods like GSM. When we are using them in application layer, we will call the same method name but different kind of modem driver.I am wondering why ofono created two different interface name and providethe same call method? > > Regards, > -Denis > > _______________________________________________ > ofono mailing list > ofono(a)ofono.org > https://lists.ofono.org/mailman/listinfo/ofono [-- Attachment #2: attachment.html --] [-- Type: text/html, Size: 2862 bytes --] ^ permalink raw reply [flat|nested] 6+ messages in thread

The basics are the same, sure. However, once you get into the details of three way calls, call waiting, multiparty calls, etc the logic and API becomes vastly different. Not to mention the various differences between carriers and their specific extensions. Bottom line is, compared to insanity of GSM/UMTS, CDMA is even more of a mess and the API needs to evolve on its own. In the future, if it makes sense to unify them, then we can do so. That time is not now. Regards, -Denis ^ permalink raw reply [flat|nested] 6+ messages in thread

I did not do anything with voicecall functionality, but you may want to look at my (not accepted) Sierra Wireless CDMA patches from earlier this year. I am also using the MC5728V. https://lists.ofono.org/pipermail/ofono/2012-December/013981.html Thanks, Forest -- Forest Bond http://www.alittletooquiet.net http://www.rapidrollout.com [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 198 bytes --] ^ permalink raw reply [flat|nested] 6+ messages in thread
