just had a questions did not know if any one could answer. i use Cisco Jabber app from market to connect to Cisco call manger i can get it to connect but if i try to make a call using sip client it will not dial using the sip client will dial to carrier and give error. but i am able to receive the call just cannot make them any suggestions.
I am looking for an application which can be installed on Android phone and work as GSM gateway. i.e. the client logs on to a SIP server, receive calls through SIP and bridge them through GSM network of the same phone. Wondering if any came across or using such app? Thanks in advance,
I've been searching long for this without luck. Curious such request was there such 2010, but no developer make it....
Hi , try www.a2voip.com
My Android 4.x phone supports SIP.
However, the options when to use the "Internet calling" are very limited: "For all calls", "Only for Internet calls", "Ask for each call".
I would like to use Internet (SIP) calls based on phones number (e.g. all international and long-distance calls should go via SIP, all phone number starting with +395656 xxx and local calls should go via my regular voice account).
I don't want to use any application like csipsimple, I want to use native support.
Android app that serves as a SIP-GSM gateway
I need an application that runs on Android phones (4.0 or above) and can send/receive calls through SIP (Can use any sip stack like sipdroid) or IAX2 and forward it to the GSM network. The application should then forward the audio and convert from SIP to GSM and vice versa.
Full description below.
Please review the attached flow diagram and confirm that you can do the job.
I wish to see a demo before accepting this work
Please review and message me with considerations. If any requirements are unable to be met, please let me know before we make a deal.

Interesting idea, 2014,jesus. Good luck!
Hello,
I've successfully added a SIP account in the native client of Android 5.1 (Cyanogenmod 12.1) and people can call me on it, works great.
I can't however make outbound calls to my contacts from it though, I don't see any option for that anywhere. Any tips?
In my old Nokia Asha long pressing the number of a contact would automatically call it via the SIP account. Is there something like this in Android?
