TL;DR
Call logging software saves each business call's number, time, duration and outcome to the right lead in your CRM. In Indian teams on Android phones, missing calls often start on the phone: battery optimisation, a SIM not selected, Truecaller as the default dialer, or a number saved in another format. Fix those, then reconcile one caller's phone log against the CRM each week.
Call logging software saves every business call (number, time, duration, outcome and often the recording) to the right lead in your CRM, either from an app on each caller's Android phone, such as Callyzer from ₹175 per number a month or TeleCRM from ₹799 per user a month billed yearly, or from a cloud phone system. When calls go missing, look at the phone before the CRM: Salestrail's help centre calls battery optimisation "the most common cause of calls not being logged on Android".
The table below covers the eight causes that call-logging vendors' own help centres name, and the weekly check after it catches the next one before your reports go wrong.
How calls get into a CRM
There are two routes, and they fail in different places.
- From the phone. An app on each caller's Android phone reads the phone's call log and uploads it. This is how Callyzer, TeleCRM, Runo (from ₹199 per user a month billed yearly for its Lite call-tracking plan) and Salestrail ($5 per user a month, billed in USD, plus $4 for CRM integration) work. It is cheap, but it only works while the phone lets the app run.
- From the phone system. A cloud business number logs each call at the provider's end and sends it to the CRM through a connector. Zoho Voice, for example, auto-logs calls into Zoho CRM, but only "if you associate the phone numbers that you'll use to make and receive calls". Nothing depends on the handset, but the connector can break.
Our explainer on CRM phone integration covers both routes and what each CRM supports.
Why calls go missing, and how to fix each cause
| Symptom | Likely cause | Fix |
|---|---|---|
| Calls missing for hours, then nothing | Battery optimisation paused the app | Set the app's battery use to Unrestricted; turn on autostart |
| App stopped logging after months unopened | Android reset its permissions | Turn off automatic permission removal; re-grant Phone and Call log |
| One phone logs no calls at all | No SIM, or the wrong SIM, selected | Select the business SIM in the app's settings |
| Calls logged, but not on the lead | Number missing or stored differently in CRM | Save every number as +91 and 10 digits |
| All calls stop for one user | CRM login expired after a password change | Reconnect the integration and check sync status |
| Some calls never detected | Truecaller as default dialer, or Wi-Fi calling | Make the phone's own app the default; turn off Wi-Fi calling |
| Calls appear late in a batch | Phone was offline | Nothing is lost; logs sync on reconnect |
| iPhone callers' incoming calls missing | Apple doesn't let apps read call logs | Dial from inside the app, or use a cloud number |
Where each fix comes from:
- Battery and autostart. Android's Doze mode "defers their jobs, syncs, and standard alarms" when the phone sits idle, and exemptions are set in Settings > Battery > Battery Optimization (Android developers). Brand skins add their own savers: Callyzer's help centre tells Samsung users to add the app to unmonitored apps, and Xiaomi, Redmi and POCO users to turn AutoStart on and set battery saver to No Restriction.
- Hibernation. If an app isn't opened for a few months, Android "places your app in a hibernation state" and resets its permissions (Android developers). A caller who only uses the phone's dialer never opens the logging app, so this happens quietly.
- SIM selection. Salestrail: "If no SIM is selected, no calls will be tracked regardless of any other settings." Runo tracks only the SIM set as the official number, and TeleCRM syncs only calls with leads on a SIM marked Personal.
- Number formats. Salestrail's "No match results found" error means the number "does not exist in your CRM". A lead saved as 098xxxxxxxx won't match a call from +9198xxxxxxxx unless the CRM normalises both.
- Expired connections. Salestrail notes integrations disconnect when "a user's CRM password changes or their authentication token expires".
- Truecaller and Wi-Fi calling. Salestrail says it is "not compatible with TrueCaller" as the default dialler, and TeleCRM tells users to "turn off Wi-Fi calling and disable (in case) Truecaller as the default dialer app".
- Offline or busy connections. Runo: "logs and recordings will sync only once you reconnect to the internet." Salestrail queues logs while a call uses the bandwidth and syncs them "typically within a minute or two of the call ending".
- iPhones. Callyzer's help centre says Apple doesn't permit any app "to access call logs", and Salestrail says iPhone inbound calls "cannot be tracked automatically".
One more to watch: some apps need the outcome before they save the rest. NeoDove's FAQ says a disposition "is mandatory after the call gets over in order to capture the call recording, talktime".
Pick an app Google Play allows to read call logs
Google Play lets an app read the call log only if it is the phone's default Phone, SMS or Assistant app, or if Google approves an exception, and business CRMs are one of the listed exceptions (Google Play policy). Call-recorder apps are not a permitted use. In practice, install call logging apps from the Play Store, not as APK files shared on WhatsApp, and expect the app to ask to be your default dialer or to explain its exception.
The 10-minute weekly call log check
We suggest running this every week, one caller at a time. It catches a broken phone before month-end reports do.
- Pick one caller and one working day from last week.
- On their phone, count calls on the business SIM in the phone's own call log for that day.
- In the CRM, count call activities for that user and day.
- If the CRM shows fewer, check the table above for that phone: battery setting first, SIM selection second.
- Open the CRM's unmatched or failed-sync list and fix any number stored in another format.
- Play three random recordings from that day to confirm they open on the lead.
- Note the phone model and the fix in a shared sheet. The same brand will fail the same way on the next caller.
New callers should get the battery, autostart and SIM settings on day one, before their first call. For tracking the team's calls once logging works, see how to track calls across a sales team, and for call tracking apps compared by price, Callyzer alternatives.
When to stop fixing phones
If you spend more time on phone settings than on calls, move calls off personal handsets. On a cloud business number, the call is logged by the phone system whichever phone answers, so battery savers, SIM slots and iPhone limits stop mattering. The cost is a monthly plan and KYC for the number; the gain is a log you don't have to audit phone by phone.
Our guide to CRMs with calling built in compares both kinds.
TalkEasy by GrowEasy: every call logged against one number
TalkEasy gives the team a cloud business number that runs in the TalkEasy app alongside each caller's own SIM, and every call is logged against that number whoever answers it. Its business dialer records each call's contact, time, duration and outcome, with a note added after the call, and call analytics show total calls, answer rate, missed calls and talk time per person, with daily and monthly reports you can download.
Pro costs ₹999 a month plus GST for unlimited users (pricing). It does not include CRM integrations: custom integration with your CRM is part of the Enterprise plan, priced on request. If your calls must land in Zoho CRM or LeadSquared today with no custom work, choose a provider with a ready connector.
